Figure 1-2Keep hands and tools clear of moving parts.

Keep clear of

moving parts toprevent serious

bodily injury.

Operating SafetyRemember SAFETY every day. Someone's LIFE maydepend on it, MAYBE YOUR OWN.

Safe operations of a crane requires a well trained,

qualified operator. Crane operation is more involved

than it may appear, and operation by a careless or un

qualified person can result in a serious accident.

When a crane is maintained and used properly it canbe a safe, highly productive piece of equipment, but if

not used properly, it can be dangerous.

Think Safety - You, the operator, are in charge of an

important piece of equipment. It is very important that

you know what it can do. It is also important that you

know what it should not do. No set of instructions can

anticipate all of the situations you will encounter. Therules given here cover the general usage, and some of

the more common specific cases. If conditions arise

not covered by these rules, contact your Link‐Belt Dis

tributor. A phone call could save someone's life.

General Safety Rules

The following is a list of safety rules which should be followed during all crane operations.

Operator Awareness1. Read, understand, and follow all instructions given

in this Operator's Manual. This Operator's Manual

contains critical information for operation and

maintenance of this crane.

Wrong

Figure 1-3Confirm the load will clear any obstructions.

2. An operator must not eat, read, or otherwise divert

his attention while operating a crane. Remem

ber-operating is a full‐time job.3. Don't smoke when fueling or fuel up near an open

flame. Keep the nozzle in contact with the filler

neck to prevent static electric sparks. Shutdown

the engine when fueling.

4. Start and operate engine in a well ventilated area.

Diesel exhaust fumes can be harmful. If it is necessary to operate in an enclosed area, vent the ex

haust to the outside. Properly maintain the exhaust

system to its original design.

5. Keep your shoes clean. Before entering the opera

tor's cab, wipe clean any mud, gravel, snow, ice,

moisture, or grease from your feet. Slippery shoes

could cause momentary loss of control of crucialfoot operated controls.

6. Keep all walking surfaces (steps, ladders, plat

forms, etc.) on the crane clean. These are to assist

operators and service personnel with safe access/

egress to/from the crane and to/from adjustment

and inspection areas. Do not allow walking surfaces to become contaminated with mud, snow,

ice, oil, paint, wax, etc. Any contamination can

cause the walking surfaces to become slick, re

ducing their effectiveness for safety while walking

on the crane.

7. Keep fingers, feet, and clothing away fromsheaves, drums, and wire ropes unless the crane

is shutdown and everyone knows what you are do

ing. Do not place a hand on wire ropes when

climbing on the crane. A sudden movement could

pull them into the drums or sheaves. Do not wear

loose clothing which may be caught in machinery.

A 3 Degree Side Tilt Can ReduceCapacities By Over 50%.

Grade Ground Level Or BlockUnder Crane. The Load Should

Hang Parallel With The Boom.

8. The operator and person in charge of the loadmust observe the following rules:

a. Loads must be well secured before lifting.

Confirm that the rigging cannot slip off or pull

away from the load, or get out of position on

the load. Ensure the load is rigged so it will not

turn over.

b. Chains and slings must be of adequate size, ingood condition, and not twisted around each

other.

c. The load must not catch on an obstruction

when lifting or swinging. Ensure the load, hoist

wire rope, or any other parts of the crane do not

snag or strike any obstruction.d. Do not allow the load to rotate out of control.

Personal injury to ground personnel, load

damage, crane damage, or damage to anti‐

two block system may occur.

e. When hoisting with single part line, especially in

long falls applications, the design of wire rope

and hook ball is crucial to minimize the potentialfor uncontrolled wire rope and/or load rotation.

Rotation‐resistant wire rope is recommended for

single part of line applications. See the Wire

Rope Capacity Chart in the Crane Rating Manual

for the specific types of rotation resistant wire

rope recommended for the crane.

f. Avoid sudden starts and stops. Lift carefully,swing gently, brake smoothly, lower and set

loads carefully. Jerking the load, swinging and

engaging swing brake roughly, and lowering

the load rapidly and slamming on brakes, will

put shock loadings and possible side loadings

on the boom. Unnecessary abuse labels the

operator as a beginner. Be a professional.g. Do not wrap the winch wire rope around the

load. Do not use discarded, worn, or dam

aged wire ropes for slings. They may break

and drop the load.

h. The crane must be level on a firm supporting

surface before making a lift. Remember, athree degree side tilt can reduce capacities by

50% or more.

The hook block and/or hook ball and hoist

wire rope can be used as a “plumb bob” to

level a crane. Pick up a compact load

2,000-3,000 lb (907-1 360kg) a few

inches (centimeters) above the ground. Ifcrane is level, hoist wire rope will hang di

rectly between the boom foot. Now swing

over the side. The wire ropes should still

hang directly between the boom foot. Be

extra careful when using this method on a

windy day.

Operator's Manual

Figure 1-5Do not let the load hit the boom or jib.

Just A Little BumpLike This ........

Can Cause This!

Wrong

Figure 1-6Do not use the boom to pull sideways.

9. Don't let the load or bucket hit the boom or jib.Don't let the boom or attachment rest on, or hit, a

building or any other object. A dent or other dam

age could result, which will weaken the boom or at

tachment. If the damage is major, the attachment

could collapse. If a lattice or diagonal bracing

member on the boom or jib is broken, cracked, or

bent, contact your Link‐Belt Distributor for repairprocedures. If the boom or jib is struck or dam

aged by anything, STOP. The loading on a boom or

attachment increases as they are lowered, there

fore their suspension systems could collapse dur

ing lowering. Use another crane to lower a dam

aged boom or attachment.10. Don't pull sideways on the boom or jib, not even a

little. Lift straight up on every load. Moving trucks,

rail cars, barges, or anything else pulling sideways

on the winch wire rope could buckle the boom or

jib. It could also damage the swing mechanism.

Pulling sideways on a boom or jib can overturn the

crane.11. Do not “two block” (pulling the hook block, hook

ball, or load into the head machinery) as this can

cause winch wire rope breakage, sheave damage,

or could pull the boom backwards over the crane

resulting in an accident.

Operator's Manual


12. Ensure the boom hoist pawl is engaged exceptwhen lowering the boom. Don't rely on the boom

hoist brake alone to hold the boom. Wear, im

proper adjustment, water or oil on linings, and

many other factors may affect the ability of the

brake to hold the boom.

13. Watch the load or a signal person at all times. A

suspended load must have your undivided attention.

14. Operate the crane from the operator's seat only.

Operating the crane from any other position, such

as reaching in a window, constitutes a safety haz

ard.

15. After slack winch wire rope operation, confirm thatthe winch wire rope is properly seated in sheaves

and on drums before continuing to operate. Use a

stick or mallet to set the winch wire rope, not your

hands.

16. Do not lower the load beyond the point where less

than three full wraps of winch wire rope are left on

the drum. This condition could occur when lowering a load beyond ground level. If all the winch wire

rope runs off the drum, the load will jerk which

could break the winch wire rope.

17. Confirm that there is a safety latch on the hook, and

that it works properly. Without a latch, it is possible

for slings or chains to come off the hook, allowingthe load to fall.

18. Don't alter any part of the crane. Additions to, or

changes in, any part of the equipment can create

loadings for which the crane was not designed.

Such changes may have a major affect the usable

capacities and make the entire capacity chart invalid. Such changes can dangerously overload or

weaken critical parts and may cause disastrous

failure.

19. Do not exceed the rated capacities of the crane un

der any circumstances. While a crane has more

stability when lifting over a corner (as compared to

straight over the side) the crane capacity is not increased. Any time the load exceeds the rated ca

pacities listed on the capacity charts in the Crane

Rating Manual, the crane is overloaded. Overloads

can damage the crane and such damage could

cause failure and accidents.

20. Lifts where two or more cranes work together canbe hazardous and should be avoided. Such lifts

should be made only under the direction of a quali

fied engineer. If a multiple crane lift is unavoidable,

observe the following rules:

a. The cranes must be level and positioned on

firm surfaces.

b. The cranes should be the same size and capacity, use the same boom length, and be

reeved similarly.

Right

Figure 1-7Use matting on soft ground.

c. Cranes must be positioned so that each boom

point is directly over its load attaching point.

The winch wire ropes must be vertical duringall phases of the lift.

d. The rigging must be placed so each crane lifts

a share of the load well within the crane's ca

pacity.

e. Ensure that during handling more load is not

transferred to any crane than it can handle.f. Don't attempt to travel when making multiple

crane lifts.

g. Coordinate plans with the other operator be

fore beginning to lift.

h. Use only one signal person.

i. Use of an operable load and angle indicating

system is desirable.21. When operating a crawler crane, where the tracks

sink into the soil any noticeable amount, use mat

ting. Timbers used for matting should be at least

as long as the total width of the lower and should

be heavy enough to withstand loadings without

damage. Timbers should be close enough to forma solid platform when lifting over lower ends (or

raising and lowering attachment). Block under

track ends so full support is provided where tracks

leave the ground. This helps keep the tracks from

digging in and cuts down on crane rocking.

Operator's Manual


Wrong

Figure 1-8Watch that lower!

22. When operating over the front or rear, use care not

to hit the lower with the load or boom.

23. When lifting submerged loads, the suction causedby the load resting on the bottom acts to increase the

weight of the load; in some cases the actual load

weight. This same effect can occur on land, when a

load is embedded in mud. To break a load loose

from suction, don't pull sideways or the boom may

collapse. If possible, rig the load so it is lifted fromone end. Don't jerk on the load. A steady pull, main

tained for several minutes, will often free the load

without over loading the equipment.

When a submerged load reaches the surface,

don't attempt to lift it out of the water all at once. It

may be saturated with water and will weigh many

times what you expect. Allow it to drain as youraise the load slowly. Be patient, as draining may

take a long time. A load when removed from the

water, will have a greater effective weight than it will

when submerged because of buoyancy.

24. Don't extract piling, casings, or other such loads by

jerking on them. The practice of pulling on the loaduntil the crane has tipped, then releasing the hoist

wire rope, allowing the crane to drop back and

catching the hoist wire rope on a clutch or brake

may break the boom. If the piling or casing won't

pull out with a smooth, steady pull, use an extrac

tor, pulling frame, or similar rigging intended forthis purpose. Pulling on a load that is not free to be

lifted can develop loadings on the crane far in ex

cess of the normal weight of the load. Lifting such

loads on a crane can damage the crane and may

cause disastrous failure. When using a pile extrac

tor, use a shock or vibration insulator unit.

Wrong

Figure 1-9Submerged Loads

25. Operating with auxiliary equipment such as pile

driver leads, pile hammers, or caisson boring at

tachments imposes additional loading in thecrane. This causes a major reduction in lifting ca

pacities of the crane. Changes in auger and kelly

bar lengths with drilling attachments and in pile

hammer attachments further complicate the man

ner in which lifting capacities are reduced. The

weight of each piece of auxiliary equipment is to beconsidered a part of the live load acting at the ra

dius of the center of gravity of the piece.

26. Demolition work can be particularly hazardous.

Shock loadings and side loadings from demolition

ball and clamshell bucket work can be severe. The

repetitive nature of such work imposes heavy de

mands on all parts of the crane. Restrict demolitionball weights to 50% of crane capacity, with the

boom length you are using, at maximum load ra

dius. In no case however, should the ball weight

exceed 50% of the available line pull.

27. When using demolition ball, avoid sudden clutch

and brake applications. Work steadily andsmoothly. Don't try to knock the whole structure

down with one blow. Use good aim. If the ball

misses its target, out swing could cause crane tip

ping or overload. When swinging back, the ball

may hit the boom and damage it.

28. Do not use the jib for demolition, drop ball, dragline, clamshell, or any other type of duty cycle ap

plication.

Operator's Manual


Wrong

Figure 1-10Extracting Pilings

29. When using a clamshell bucket on demolition work

and taking a bite on a piece of unknown weight, be

ready to release the closing line as more weightthan can be lifted may break loose. Be prepared to

drop the load. Always remain within the boom

length and load limitations shown in the Crane Rat

ing Manual. Failure to do so may fatigue compon

ents which can lead to eventual failure.

30. When dismantling a structure where a portion isbeing cut loose while suspended by a crane, con

firm that the weight of the portion being cut loose is

known, and the crane pull on the load is equal to

the weight. The point of attachment must be di

rectly above the center of gravity of the load. The

hoist wire rope must be vertical. This is an ex

tremely hazardous operation. The services of aprofessional engineer should be used to plan and

supervise such lifts.

31. Cold weather operation requires some special at

tention by the operator to allow for changes in eve

ryday routines:

a. Clean all snow and ice from all steps, ladders,platforms, etc. to eliminate slippery walking

surfaces.

b. Clean the crane, especially the boom, of accu

mulated amounts of ice or snow. Operating

the crane with an ice or snow covered boom is

dangerous. The added weight of the ice orsnow can drastically reduce the capacity of the

crane. Also, falling ice may pose danger for

ground personnel.

Wrong

Figure 1-11Demolition Work

c. If cold weather starting aids are provided on

the crane, use them. The use of aerosol start

ing sprays can be dangerous if the manufacturer's directions are not closely followed.

d. Pay close attention to the gauges in the opera

tor's cab when starting the engine. Normal

“warm up” times will be longer. Ensure pres

sures and temperatures are within normal

ranges before beginning operations.e. Always handle flammable materials according

to the supplier's instructions. Propane, diesel,

or other fuel, for auxiliary heaters, can be dan

gerous if not properly handled. Do not store

such fuels on the crane.

f. Use caution when lifting any load during freez

ing weather, as it may be frozen to the groundor the supporting surface. The added tension,

to break the load free, could cause an unex

pected overload situation. Also, when the load

does finally break loose it could create an er

ratic motion causing damage or injury.

g. At the end of the work shift, park the cranewhere it will not freeze to the ground. Major

damage to the drive train could occur while try

ing to free the crane from a frozen surface.

Boom Safety Instructions

Disassembly of any pin connected boom can be haz

ardous. Removing the wrong connecting pins or re

moving the connecting pins without first properly posi

tioning pendants will cause the boom to fall. If you are

under the boom when it falls, you may be killed. If there

is any doubt in your mind about the boom disassembly

procedure, block tightly under both ends of each boomsection before removing any of the connecting pins.

The following points must be observed while

performing any boom assembly or disassembly:

1. Read and understand the step by step instructionsoutlined in this Operator's Manual before

attempting to assemble or disassemble the boom.

2. Do not stand inside, on top, or under the boom at

any time while assembling or disassembling the

boom.

3. Do not climb, stand, or walk on the boom. Use a

ladder or similar device to reach necessary areas.4. When removing or installing the boom section

connecting pins, drive the pins from outside the

boom toward the inside.

could result in an accident.

7. Do not remove any connecting pins which are

located behind the pendants which are supporting

the boom.8. Stay clear of pinch points when aligning boom

section connecting lugs. Never place your fingers

in connecting pin holes.

9. Know the maximum amount of boom that can be

cantilevered, projected beyond the point of sus

pension, during boom assembly and disassembly.Exceeding this amount can cause boom or boom

suspension failure. Refer to Section 4 of this Oper

ator's Manual for specific boom assembly proce

dures.

10. If the boom length is such that midpoint pendants

are required, ensure they are installed and properly adjusted. Long booms may buckle in the mid

dle from their own weight without the midpoint

pendants.

11. Use caution when disconnecting the dead end of

wire ropes. Reeved wire rope can become twisted

on the sheaves. When the dead end pin or socket

is removed, the wire rope may spin.

12. Use care handling the boom and jib sections whenloading, transporting, and unloading. Damage

that occurs during these operations can go un

detected and could result in failure of the attach

ment, once subjected to loading. Pay attention to

the pendants if they are stored on the top of the

boom sections to prevent damaging them. Also

use care to prevent damaging the live mast barpendants, if equipped. Do not attach slings to the

lattices as they will bend. It is recommended that

the connecting lugs or main chords be used as lift

ing points. Use only soft nylon straps minimum 3

inches (7.62cm) in width of sufficient strength,

around all four main chords, to handle sections.13. Block under and between the boom and jib sec

tions when loading them on a transport vehicle.

When securing sections to a transport vehicle, it is

best to use synthetic webs or slings. If using wire

rope slings, pad the section to protect it from dam

age. Do not overtighten the tie downs or the sec

tion may be damaged. Do not use chain tie downs,as they may dent and damage the section.

14. Thoroughly inspect all the elements of each boom

or jib section before installing it on the crane.

Check each main chord, picture frame, diagonal,

lattice, and connecting lug for bends, dents, and

cracked or corroded welds. Picture frames mustbe square. Do not use any boom or jib section that

is even slightly damaged. Contact your Link‐Belt

Distributor for the proper repair procedures.

Electrical Dangers1. All electrical power lines are dangerous. Contact

with them, whether insulated or not, can cause

death or injury. When operating near power lines,

the best rule is to have the power company turn off

the power and ground the lines. However, in some

cases, the operator may be unable to have the

power turned off. Follow these rules whether thepower is turned off or not.

a. Be alert. You are working around conditions

which can cause death.

b. Keep all parts of the crane, wire ropes, hook

block, hook ball, and load, at least the distance

from power lines as specified in the “High Voltage Power Line Clearance Chart” or other dis

tances specified by applicable codes. Slow

down crane operation.

c. Assume that every line is electrically energized

(“Hot” or “Live”).

d. Appoint a reliable person equipped with a loudsignal (whistle or horn) to warn the operator

when any part of the crane is working around

the power line. This person should have no

other duties while the crane is working around

the power line.

e. Erect a suitable barricade to physically restrain

the crane and all attachments (including theload) from entering an unsafe distance from

f. Warn all personnel of the potential danger.

Don't allow unnecessary persons in the area.

Don't allow anyone to lean against or touch thecrane. Don't allow ground workers to hold

necessary. In these cases use dry plastic

ropes as tether lines. Make certain everyone

stays at least the distance from the load, as

specified in the “High Voltage Power LineClearance Chart”, or such distance as re

quired by applicable codes.

g. The use of boom point guards, proximity de

vices, insulated hooks, or swing limit stops do

not assure safety. Even if codes or regulations

h. Grounding the crane can increase the danger.

Poor grounding such as a pipe driven into the

ground, will give little or no protection. In addition, a grounded crane may strike an arc so

heavy that a live line may be burned down.

This could cause the crane and the area

around it to be electrified.

i. When operating near radio or T.V. transmitting

stations, high voltage can be induced in metalparts of the crane, or in the load. This can oc

cur even if the crane is some distance from the

transmitter or antenna. Painful, dangerous

shocks could occur. Contact trained elec

tronic personnel before operating the crane to

determine how to avoid electrical hazards.

j. Overhead lines can move when the wind blowsagainst them. Allow for this when determining

safe operating distances.

ple: If you swing left to the wire, swing to the

right to break contact. Remember - once an

arc has been struck, it will stretch out much far

ther than you think before it breaks. Keep moving until the arc has been broken.

e. When the arc breaks, continue moving away

until you are at least 15 ft (4.57m) away (or a

distance specified in the “High Voltage Power

Line Clearance Chart” or as specified by local

codes). Stop the crane. Make a thorough inspection for crane damage before further use.

Radio Frequency Or Electro MagneticInterference (RFI Or EMI)

Certain areas may contain high Radio Frequency OrElectro Magnetic Interference (RFI or EMI). In these

areas the boom can act like an antenna and produce

an electrical current that may cause electrical shocks

and/or the crane to malfunction. If operating in an area

where these conditions may exist, test the crane or

have the area tested for the magnitude of this interfer

ence before operating the crane. Operation may notbe possible or boom length may be limited. Comply

with all local, state, and federal laws when operating in

high RFI/EMI areas.

Protective Equipment1. Always replace protective guards and panels be

fore operating the crane.2. Always wear hard hats, safety glasses, steel toe

shoes, hearing protection, and any other safety

equipment required by local job conditions,

OSHA, or regulations. Do not wear loose clothing

which could get caught in moving machinery.

3. Always wear safety glasses when drilling, grinding,or hammering. Flying chips could injure the eyes.

4. Always wear a mask to prevent breathing any dust,

smoke, fumes, etc. while cleaning, drilling, weld

ing, grinding, sanding, etc. on any part of the

crane. Breathing dust, smoke, fumes, etc. can be

very hazardous.

5. Keep a dry chemical or carbon dioxide fire extinguisher of 5BC rating or larger in the operator's cab

or in the immediate area of the crane at all times.

Instruct all operating and maintenance personnel

in proper use of the extinguisher. Check periodi

cally to confirm that it is fully charged and in work

ing order.

Wrong

Figure 1-24Use a signal person, back safely.

6. Do not tamper with safety devices. Keep them in

good repair and properly adjusted. They were put

on the crane for your protection.7. When operating a crane equipped with any form of

load indicating mechanism, overload warning sys

tem, anti‐two block system, or any automatic

safety device, remember that such devices cannot

replace the skill and judgment of a good operator.

For instance, such devices cannot tell when acrane is positioned on a supporting surface that

will give away, that too few parts of line are being

used to lift a load, cannot correct for the effects of

wind, warn that the device may be improperly ad

justed, correct for side pulls on the boom, or for

many conditions which could occur and create

hazards. It requires all the skill, experience, judgment, and safety consciousness that a good op

erator can develop to attain safe operation. Many

safety devices can assist the operator in perform

ing his duties, but he should not rely on them to

keep him out of trouble.

Signal Persons And Bystanders1. Don't allow crane boom or loads to pass over peo

ple or endanger their safety. Remove all loose ob

jects from load. All unnecessary personnel should

leave the immediate area when crane is operating.

2. Do not allow anyone to ride on the hook block,

hook ball, or any part of the load or attachment forconstruction work or recreational activities. (This

applies to recreational activities such as “bungee

jumping” or “bungee cord jumping”.) Cranes are

intended to lift objects, not people. They are not

elevators.

3. Do not carry passengers! There is only one seat

and it is for the operator. A fall from the crane cancause death or serious injury.

4. Always look before you back up, or better yet, post

a signal person to guide you. If crane is equipped

with a back up alarm, confirm that it is working

properly. Use the horn as a signal. Use a codesuch as one beep - stop, two beeps - forward,

and three beeps - backward. Ensure everyone on

the job site knows the code.

5. Do not make a lift which is not in plain sight. This

can lead to an accident or crane damage. Post a

signal person, if necessary, to fully observe the

situation and guide the operator.

Crane Inspections And Adjustments1. Inspect crane daily. Do not operate a damaged or

poorly maintained crane. Pay particular attention

to the clutches, brakes, attachments, and wire

ropes. If a component is worn or damaged, re

place it before operating. Clutch and brake linings

must be dry and oil free. Oil soaked linings must be

replaced.2. Labels, plates, decals, etc. should be periodically

inspected and cleaned as necessary to maintain

good legibility for safe viewing. If any instruction,

caution, warning, or danger labels, decals, or

plates become lost, damaged, or unreadable, they

must be replaced.3. When performing repetitive lift applications, espe

cially at or near maximum strength limited capaci

ties, an inspection of the major structural areas of

the crane, for cracks or other damage, should be

conducted on a regular basis. (A non‐destructive

test such as magnetic particle or dye penetrantmay even be considered.) Along with inspection

for cracks and damage, frequently check the criti

cally loaded fasteners, such as the turntable bear

ing mounting capscrews, to ensure they have not

been stretched. Not only does frequent inspection

promote safety, but it is also much easier and less

expensive to perform a repair when a crack issmall, before it has a chance to traverse through a

structural member. Any sign of cracks or damage

must be repaired before continuing operations.

Contact your Link‐Belt Distributor for repairs.

4. When performing maintenance on the crane, do

the following:a. Lower the boom to the ground.

b. Shutdown the engine and work all control lev

ers back and forth to relieve pressure and relax

the attachment.

c. If the above instructions cannot be followed,

block securely under the attachment so it can

not move.d. Bleed any precharge off the hydraulic reservoir

before disconnecting any line.

e. Hydraulic oil becomes hot during operation. In

some cases it becomes hot enough to cause

severe burns. Be careful not to let hydraulic oil

come in contact with skin.f. Disconnect battery cables and remove ignition

key so crane can't be started. Post warning

signs in operator's cab so no one will try to start

the engine. Never adjust, maintain, or repair a

crane while it is in operation.

Operator's Manual


5. When making repairs, which require welding, useproper welding procedures. Also the following

precautions must be taken:

a. All paint in the area should be removed to pre

vent burning the paint. The smoke and fumes

from the burning paint can be very hazardous.

b. Disconnect the batteries.

c. The welding ground cable should be attachedto the portion of the crane being welded. If

welding on the upper, ground on the upper. If

welding on the lower, ground on the lower.

Failure to take this precaution may result in

electrical arcs in the turntable bearing.

d. The welding ground cable should always beconnected as close as possible to the area be

ing welded. This minimizes the distance that

electricity must travel.

e. Disconnect computers and other electronic

equipment (such as load moment limiters) to

prevent damage. Contact your Link‐Belt Dis

tributor or factory for proper procedures.f. Remove all flammables from the proximity of

the welding area.

6. Keep the crane clean, in good repair, and in proper

adjustment. Oil or grease on the walkways may

cause falls. Improper adjustments can lead to crane

damage, load dropping, or other malfunctions.7. Keep all walking surfaces (steps, ladders, plat

forms, etc.) on the crane clean. These are to assist

operators and service personnel with safe access/

egress to/from the crane and to/from adjustment

and inspection areas. Do not allow walking sur

faces to become contaminated with mud, snow,ice, oil, paint, wax, etc. Any contamination can

cause the walking surfaces to become slick, re

ducing their effectiveness for safety while walking

on the crane.

8. Use extreme caution when removing radiator

caps, hydraulic pressure caps, etc. They can fly off

and hit you, or you could be burned by hot oil,water, or steam.

WARNINGBattery posts, terminals, and relatedaccessories contain lead and lead

compounds. Wash hands after handling.

9. When checking battery fluid level, use a flashlight,

not an open flame. If the battery explodes, you can

get acid in your eyes, which could cause blind

ness. Don't check battery charge by shorting

across posts. The resulting spark could cause thebattery to explode. Check with a tester or hy

drometer. Don't smoke near batteries.

Figure 1-27Do not use an open flame near the battery.

10. When using jumper cables to start an engine, al

ways connect negative post to negative post, and

positive post to positive post. Always connect thetwo positive posts first. Then make one negative

post connection. Make the final negative connec

tion a safe distance from the battery. It can be

made on almost any bare metal spot on the crane.

Any spark could cause the battery to explode.

11. Test the winch brake by raising the load a fewinches (centimeters) and holding. It should hold

without slipping. It takes more braking power to

hold a load in the air when the drum is full of wire

rope than when it is a few inches (centimeters)

above the ground with only a few wraps on the

drum.

12. Always reduce pressure in hydraulic system tozero before working on any part of the system.

13. Use extreme care when working on circuits with

accumulators. Check that hydraulic pressure is re

lieved before opening the circuit for repairs.

14. When setting pressures, never exceed the manu

facturer's ratings. Always follow instructions exactly. Over pressurization can cause hydraulic

component damage or failure of mechanical parts

on the crane. Either of the above can lead to an ac

cident.

Figure 1-28Do not operate the crane

with worn or damaged wire rope.

“I thought I could savemoney by running this

wire rope until Friday”.

Wrong

Wire Rope1. Inspect all wire rope thoroughly. OSHA (Occupa

tional Safety And Health Act) regulations state “all

wire ropes in active service should be visually in

spected once each working day. A thorough in

spection of such wire ropes should be made at

least once a month and dated records kept as towire rope conditions”. Replace any worn or dam

aged wire rope. Pay particular attention to winch

wire ropes. Check end connections (pins, sock

ets, wedges, etc.) for wear or damage.

2. Non‐rotating, rotation‐resistant, or spin‐resistant

wire ropes are recommended for single part of lineapplications. This is of utmost importance for long

fall hoist wire rope applications. Only if certain cri

teria are met may a swivel hook ball be used with

rotation resistant wire rope. Refer to “Single Part

Line Hoisting” and “Hook Ball Usage With Rotation

Resistant Wire Rope” in Section 5 of this Opera

tor's Manual.3. Use at least the number or parts of winch wire rope

specified on the Wire Rope Capacity chart in the

Crane Rating Manual to handle the load. Local

codes may require more parts of line than is

shown. Check code requirements and use them

where applicable.4. Do not handle wire rope with bare hands. Always

use gloves to prevent possible injury from frayed or

damaged areas in the wire rope.

5. Inspect head machinery and hook block often, as

damaged or deteriorating sheaves can cause ex

cessive wear of the wire rope.6. When reeving wire rope on the crane, do not climb,

stand, or walk on the boom or jib. Use a ladder or

similar device to reach necessary areas.

Crane And Area Clearance1. Know your job site conditions. Familiarize yourself

with work site obstructions and other potential haz

ards in the area which might lead to mishaps.

Make any necessary arrangements to eliminate

any potential hazards, if possible.

2. Erect barricades around the immediate work areato prevent unauthorized personnel from wander

ing onto the job site.

3. Confirm that your work area is clear. Ensure you

have proper clearance for the crane, boom, and

load. Don't swing, travel, lift or lower loads, or raise

or lower jacks, without first making sure no one is inthe way. If your vision is obscured, position a signal

person so you can see him, and he can see all areas

you can't. Follow his signals. Confirm that you and

the signal person understands each other's signals.

See Hand Signals Chart in Figure 1-84. Use the

horn to signal or warn. Ensure everyone on the job

site understands signals before starting operations.4. When working inside a building, check overhead

clearance to avoid a collision. Check load limits on

floors or ramps so you won't crash through.

5. Don't operate close to an overhang or deep ditch.

Avoid falling rocks, slides, etc. Don't park crane

where a bank can fall on it, or it can fall in an excavation. Don't park where rain can wash out footing.

6. Pinch points, which result from relative motion be

tween mechanical parts, can cause injury. Keep

clear of the rotating upper or moving parts.

7. Watch the tailswing of the upper revolving frame

and counterweight. Even though the originalsetup may have been clear, situations change.

8. Do not store material under or near electrical

power sources. Make material handlers aware of

the dangers involved with storing material under

power lines or in the vicinity of any other hazards.

Operator's Manual


Weights, Lengths, And Radii1. Know your load. Don't try to guess or estimate the

load. Use a scale or a load indicating system to de

termine exact weight. Remember the weight you

are lifting includes the weight of any lifting slings or

gear, the hook block, hook ball, and any other

weight on the hook. If lifting off the boom with the

jib installed, the weight of the jib and rigging mustalso be considered as part of the load. Refer to

“Capacity Deductions” in the Crane Rating Manual

for amounts to be deducted.

The total load weight must never exceed the rated

capacity of the crane, as listed on the capacity

charts in the Crane Rating Manual for the position,boom length, load radius, and condition of opera

tion being used. Remember - the rating listed on

the capacity charts in the Crane Rating Manual are

based on ideal conditions:

a. Standing on firm, level surface.

b. Calm wind.c. No side loads or out swing of load.

d. Good visibility.

e. Crane in top condition and equipped as when

leaving the factory.

When such conditions cannot be attained, loads

being handled must be reduced to compensate.

The amount loads are reduced depends upon howgood or how poor, the actual operating conditions

are. It is a matter of judgment and experience.

When in doubt, do not take a chance. Reduce rat

ings more than you think you need. Some factors

which may require reduction of capacities are:

a. Soft or unpredictable supporting surfaces.b. Wind.

c. Hazardous surroundings.

d. Inexperienced personnel.

e. Poor visibility.

f. Fragile loads.

g. Crane in poor condition.

When lifting loads with large surface areas, such asbuilding panels, in a wind, the movement of the

load may pose a danger to workmen or building

structures. Out swing of a load will increase the

load radius, and may overload the crane. This

could lead to boom failure or the crane tipping.

Wrong

Figure 1-30Know your load.

“It looked likeabout 5 tons”.

2. Avoid working a crane in high winds. If you must

work in a wind, reduce capacities as shown in

“Wind Restrictions Guide” in the Crane RatingManual. Wind blowing against the load and the

boom produces a side load on the boom and re

duces its capacity.

3. When operating off the main boom with the jib or

other attachment erected, deductions must be

made for its weight. The weight of the added attachment, pendants, etc., must be considered to

obtain a “NET”capacity. Failure to do so could re

sult in an overloading condition and cause boom

failure. Refer to “Capacity Deductions” in the

Crane Rating Manual for amounts to be deducted.

Operator's Manual


Wrong

Figure 1-31Do not lift two loads at the same time.

4. Do not lift two loads (on the boom and jib) at the

same time, even if the total load weight is within

crane capacity. Loads on the boom and jib at thesame time, stress the boom and drastically reduce

its ability to handle loads. Your full attention cannot

be given to both loads, creating a dangerous situ

ation.

5. Some capacities on cranes are based on strength

of materials. In these cases, overloads will causesomething on the crane to break, before it will tip.

Do not use signs of tipping as a warning of over

load.

6. Don't lash a crane down. Lashing a crane down

encourages overloading. Crane damage or injury

could result.

7. Do not shock load and/or overload the crane atanytime. Shock loading or overloading the crane

will reduce the fatigue life of crane components

and could result in component failure.

8. When performing repetitive lift applications, espe

cially at or near maximum strength limited capaci

ties, be aware that these applications may reducecomponent life. These applications include re

peated lifting (or lifting and swinging) of near 100%

strength limited capacities and repeated lifting

maximum moment loads. These applications may

fatigue the major structural portions of the crane.

Although the crane may not break during these applications, they can reduce the fatigue life and

shorten the service life of the crane. To improve the

service life, while performing repetitive lift applications, consider reducing the capacities to 70% of

maximum strength limited capacities to reduce fa

tigue cracking. Frequently perform a thorough in

spection of all the structural areas of the crane.

Any sign of cracks or damage must be repaired be

fore continuing operations. Contact your Link‐Belt

Distributor for repairs.9. Always refer to the appropriate capacity chart in

the Crane Rating Manual after changing the ar

rangement of the attachments for the correct lifting

capacities.

10. All booms must be assembled in the correct man

ner before making a lift. The capacity charts in theCrane Rating Manual for such booms are based on

proper boom make‐up. Correct placement of

boom extensions, based on length is crucial. Refer

to the “Suggested Boom Make‐Up Chart” in Sec

tion 4 of this Operator's Manual for correct boom

section arrangements.

11. Do not use the boom to push or pull. It is not designed for this purpose. Such action can damage

the boom and lead to an accident.

12. Know the load radius. Don't guess at it. Determine

the load radius by using the boom angle indicator,

the boom length, and the capacity charts in the

Crane Rating Manual, or measure it with a steeltape. Remember - Radius is the horizontal dis

tance from the centerline of rotation of the upper to

the center of gravity of the load, when the load is

hanging free.

13. Do not operate the crane at radii or lengths where

the capacity charts in the Crane Rating Manualshow no capacity. Don't use a boom or jib not

shipped with or for your crane. Either of the above

can tip the crane over or cause attachment failure.

In some cases, the crane can tip over forward or

backward with no load on the hook! Also, if the

boom is long at a low angle, the crane may tip until

the boom touches the ground. In any of thesecases, injury or crane damage could result.

14. When you lift a load with any crane, the load may

swing out or sideways. The load radius will increase.

The increase or out swing of the load can overload

the boom, and lead to boom failure or tipping. Also,

movement of the load can cause it to hit something.Confirm that the load being lifted will remain within

capacity as it is lifted and the boom deflects.

15. When lowering a boom with a load, the load radius

increases. As the load radius increases, capacity

decreases. If capacity is exceeded, the boom may

fail or the crane may tip. Sometimes at low angles,

the boom can be lowered with a load, but cannotbe raised. If an operator lowers the boom under

load, he may not be able to raise the boom and

may get into a dangerous situation.

Operator's Manual


Wrong

Figure 1-32Use caution when booming to minimum radius.

16. Use caution when booming up to minimum radius.

Be prepared to stop boom travel. If the boom limit

device malfunctions, the boom and backstopsmay be damaged, or someone may be hurt. Do

not intentionally boom into boom limit device dur

ing normal operation.

17. When operating near minimum radius, be ready to

boom down as you set the load down, to compen

sate for the tendency of the boom to move backagainst the backstops when the load is released.

This action occurs because of the elasticity in the

boom and boom hoist system. Major bending in

the boom can occur if it is allowed to bear against

the backstops too heavily.

18. When booming down, the load will move away

from the crane and lower as well. To keep the loadfrom lowering as it moves away from the crane, the

operator must hoist up on the winch wire rope si

multaneously. When booming up, the load will

move toward the crane as well as raise. When

booming up, the operator must hoist down as well

to keep from raising the load. Booming up withoutwinching down, can lead to “two blocking”. This is

when the hook block, hook ball, or the load con

tacts the head machinery. Two blocking can lead

to sheave or wire rope damage.

Right

A

B

Figure 1-33Boom Angle And Single Part Line Operation.

19. Know the boom length. Don't guess. Use of an in

correct boom length can cause an accident.

20. Use special care when handling loads on singlepart line with boom at or near minimum radius. In

single part line operation, ensure angle “A” is al

ways greater than angle “B”, or the boom could fall

backwards uncontrollably. Refer to Figure 1-33.

This situation is more likely when the winch wire

rope is off the rear drum.

WARNINGUse a minimum of 2 parts of line with the 30 ton(27.2mt) hook block when using the basic

boom. Live mast can overhaul boom at short

radii. Major crane damage and/or serious

personal injury could occur.

Just a little side tilt whenworking over the end.

Look what happens over the side. . . .

LOAD RADIUS INCREASESBY THE AMOUNT OF SIDE TILT!

SIDE TILT

Wrong

Wrong

Figure 1-34Watch that side tilt!

21. The winch wire rope must be vertical when starting

to lift. If not, the load will swing in, out, or sideways

when lifted from the ground. The crane will lean toward the load when lifting heavy loads. This is

caused by elasticity of the crane and the boom.

Wrong

12

Figure 1-35Watch that centrifugal force!

1. Load Radius At Rest

2. Load Radius Increases Due To Centrifugal Force

This lean will increase operating radius so the load

will swing outward when it clears the ground. This

out swing is dangerous to anything in the path ofthe load, and because of the increase in load ra

dius may overload the crane. To overcome this out

swing, boom up as the load is lifted so winch wire

ropes remain vertical. When setting the load on the

ground, lower boom after the load touches down to

avoid hook block and/or hook ball spinning when itis unhooked from load, or the boom contacting the

backstops.

22. Lifting heavy loads can cause the crane to tilt or

lean toward the load. When swinging a load from

over the end to over the side, the tilt of the crane will

increase. Since tilt acts to increase load radius, it

must be compensated for when swinging the load.Swing slowly. Change boom angle (raise the

boom) while swinging, to maintain a constant ra

dius, and prevent in swing or out swing of load. If

not, a dangerous condition could result.

23. Watch out for centrifugal force when swinging a

load. Swing gently. Centrifugal force tends to increase load radius. This increase in radius could

overload the crane and cause crane damage or tip

ping. When stopping the swing, over swing of the

load can side load the boom.

Operator's Manual


24. Keep the winch wire ropes as short as possible toprevent excessive swinging. Always use the short

est boom length which will do the job. Remember

- the shorter the boom, the better the capacity.

25. Do not move a crane away from the load while han

dling near capacity loads. Due to load inertia

(weight) the load will tend to stay in position when

the crane starts to move, and then will swing in towards the crane. The inertia effect will tend to in

crease load radius and decrease stability. This

could lead to boom failure or crane tipping.

26. Know how much counterweight is on the crane.

The capacity charts in the Crane Rating Manual

may list different capacities for differing amounts ofcounterweight. Ensure that you know how your

crane is equipped and use the correct column on

the chart to ensure proper load limitations.

Don't modify the counterweight(s). Don't store

anything on the crane that will act as additional

counterweight. Remember that anything which

has weight, if carried behind the crane's center ofgravity, acts as counterweight. Adding counter

weight affects backward stability of the crane, par

ticularly when working over the side. It also en

courages overloading of the crane.

27. Working areas for cranes are defined per the Work

ing Areas diagram in the Crane Rating Manual.Permissible loads, per the Crane Rating Manual,

may vary from lifting quadrant to lifting quadrant.

The operator must ensure capacity ratings are not

exceeded regardless of which quadrant he is oper

ating in, or when swinging from one quadrant to

another.

Traveling1. Avoid traveling over obstacles: rough terrain,

rocks, logs, curbs, ditches, etc. The size and type

of obstacle that can be safely crossed will depend

on many factors, including good judgment. When

obstructions must be crossed, do so with extreme

caution, at an angle if possible, and at slow speed.Ease up to the break over point, balance on the ob

struction, and then ease down to minimize jolt of

contact of the other side.

2. Cross a gully or ditch at an angle and very slowly.

Carry boom at a low angle for increased stability.

Wrong

Figure 1-36If possible, go around obstacles.

3. Avoid side‐hill travel whenever possible. Travel up

or down the slope. Shift crane to lowest speed

when starting up or down the slope. Keep theboom facing downhill and close to the ground.

Traveling up the hill with the boom at a high angle

should be avoided. Depending upon the slope of

the grade, the angle may be such as to allow the

boom to fall backwards over the lower. If the crane

starts slipping sideways on a grade, immediatelyturn the crane down the grade.

4. When moving the crane around on the job site with

the attachment in the air, observe the following pre

cautions:

a. Swing upper so it is centered over the front or

rear of the lower. Engage the swing lock.

b. Terrain must be smooth and solid. If not, gradethe area before moving the crane.

c. Tie down the hook block and/or hook ball to

prevent them from swinging when moving.

d. Boom must be at an intermediate radius,

approximately 60°, unless you are traveling up

or down a grade. In this case a lower or higherboom angle may be the more stable condition.

e. Position a signal person to guide you.

f. Avoid traveling on a grade, particularly a side

slope. If you must travel up a slope, back up

the grade for maximum crane stability and

minimum side loadings.

Figure 1-37Watch for narrow or low clearances.

5. Traveling with a suspended load should beavoided if possible. It is especially hazardous

when terrain is rough or irregular, on a side slope,

or in a hilly area. When traveling with a load, ob

serve the following rules:

a. Use a hand line to control the load and reduce

load swing.

b. Travel by the smoothest, most level route. If asmooth, level route is not available, don't travel

with a suspended load. Grade the route to pro

vide a smooth, level path. If it is not possible to

grade the route, move the load by stepping.

Level the crane, lift the load, and set it down

ahead of the crane. Travel the unloaded cranebeyond the load, level the crane, lift the load,

swing, and set it down farther along the route.

Continue this procedure until the load is at its

destination.

c. Carry loads as close to the ground as possible.

d. Do not allow side swing of the load.

e. Don't attempt to carry loads which exceed thecrane's rating as listed in the Crane Rating

Manual.

f. Use a signal person to warn of any danger or

obstruction along the route being traveled.

g. Don't travel with a load on soft ground. If thecrane sinks into the ground, stability can be af

fected to the point of tipping the crane.

h. Keep all personnel clear of crane and load. Be

prepared to set load down quickly at any time.

6. When transporting the crane, note the following:

a. Operate with lights on. Use proper warning

signs, flags, and other devices. Use an escortservice if required.

b. Engage the travel swing lock.

c. Remove or restrain the hook block and/or

hook ball.

d. Check for maximum allowable travel speed,

maximum amount of boom that can be transported, and any other travel limitations. Don't

exceed these maximums. Crane damage or

an accident could result.

e. Watch for narrow bridges and low clearances.

f. Check load limits, heights, width, and length

restrictions in the area you are traveling.

g. Confirm that your crane complies with all regulations.

Figure 1-38Do not leave the crane with a load suspended.

Leaving The Station1. Do not get on or off a crane in motion. Use the grab

handles and ladders when climbing on or off the

crane. Remain in three point contact with the crane

at all times (two hands and one foot, or two feet and

one hand).

2. Whenever an operator leaves the control station for

any reason, the following must be done:a. Lower the load to the ground.

b. Engage the swing lock, engage all drum

pawls, and move the control lockout switch to

the off position. Shutdown the engine and re

move the keys.

c. Do not depend on a brake to suspend a loadunless the operator is at the controls, alert, and

ready to handle the load. Brake pedal locks

are intended to allow the operator to rest his

legs when suspending a load, but the operator

must remain in his seat with his feet on the ped

als. Brake slippage, vandalism, or mechanicalmalfunctions could cause the load to drop.

3. Do not leave crane unattended with engine run

ning.

4. When changing work shifts always notify the next

operator of any changes or problems with the

crane.

Personnel Handling Guidelines

Introduction

The following information is intended to provide Link‐

Belt's recommended minimum requirements that must

be followed when handling personnel with a personnel

basket or work platform (hereafter referred to as a workplatform) suspended by wire rope from the boom of

Link‐Belt cranes. These requirements are based upon

several sources and are put forth in recognition of cur

rent industry practices. However, safety, when hand

ling personnel, remains the full responsibility of job site

management and is dependent upon the responsible

action of every person on the job involved in the relatedwork.

This information is intended to supplement and not to su

persede or replace any more restrictive federal, state, or

local regulations, safety codes, or insurance require

ments. It is intended to serve users of personnel work

platforms in achieving the following objectives.1. Reduce risk of personal injuries to users and the

public.

2. Inform users of their respective responsibilities.

3. Provide standards of equipment requirements.

4. Provide standards for tests and inspections.

5. Provide standards of operation to promote safety.

Link‐Belt cranes are designed and intended for handling material. They are not normally equipped with sec

ondary systems or other devices required by person

nel lift or elevator standards and are not intended for

handling personnel for construction or amusement

purposes. Use of cranes for these purposes is hazard

ous and is not recommended by Link‐Belt. However,Link‐Belt understands that circumstances may occur

(in construction work) when lifting or lowering person

nel on a materials handling crane load line is the only or

the least hazardous method available to position per

sonnel. In fact, Occupational Safety and Health Admin

istration (OSHA) Part 29, CFR 1926.1431 states “The

Operator's Manual


use of equipment to hoist employees is prohibited except where the employer demonstrates that the erec

tion, use, and dismantling of conventional means of

reaching the work area, such as personnel hoist, lad

der, stairway, aerial lift, elevating work platform, or scaf

fold, would be more hazardous, or is not possible be

cause of the project's structural design or worksite

conditions.”

Much corollary and supplementary information is con

tained within the following resource documents per

taining to both cranes and personnel work platforms.

Job site management must ensure all requirements lis

ted in these resource documents are followed for all

personnel handling operations.� American National Standards Institute Reference -

ANSI Standards A10.28, A92.2, A92.3, B30.5, and

B30.23.

� American Petroleum Institute (A.P.I.) Specification 2C.� OSHA Part 29, CFR 1926.1431 Cranes and Derricks.

Authorization

Authorized use of a work platform may be permitted

only after the following on‐site procedures have been

performed:

1. A competent person on the job site (job site manager) specifically responsible for the overall work

function to be performed has determined that

there is no practical alternative means to perform

the needed work and has authorized a personnel

lifting operation.

2. For each instance of such lifting, a competent person responsible for the task has attested to the

need for the operation by issuing a written state

ment describing the operation and its time frame

and itemizing that each of the on‐site authorization

requirements has been met. The written state

ment, after being approved by a qualified person,

shall be retained at the job site. (Refer to PersonnelHandling Pre‐Lift Check List For Link‐Belt Cranes in

this Section for a sample check list.)

3. Review of crane inspection records has been con

ducted to ensure the crane being used meets ap

plicable provisions in ANSI B30.5 and B30.23.

4. Review of the work platform inspection recordsand specifications has been conducted to ensure it

meets applicable design standards (refer to ANSI

A10-28).

5. Review of the personnel lifting operation practices

specified in these instructions have been conduc

ted with job site managers and crane operator(s),foreman, designated signal person, personnel to

be lifted, safety supervisor, and any other person(s) who has jurisdiction over the operation to

ensure that they are aware of the hazards of the op

eration and they are aware of provisions of these

instructions that must be adhered to before and

during the personnel lifting operation.

Equipment1. The crane system shall be equipped with the fol

lowing:

a. A fully functional working operational aid such

as a Rated Capacity Limiter (RCL) system - A

system consisting of devices that sense crane

loading, boom length (extendable booms

only), boom angle, and also automaticallyprovide an audible/visual signal when the

loading conditions approach, reach, and/or

exceed the rated capacity values. When the

Actual Load exceeds the Rated Capacity, the

system supplies a signal to a function cutout

system. The operational aid shall be equippedwith these additional devices:

1. Anti‐two block device to prevent damage

to the hoist wire rope, other crane com

ponents, or attachments, and subsequent

endangerment of personnel.

� It is required that the anti‐two block

device warn both audibly and visually aswell as have the capability to cutout the

controls/functions that may cause a two

block condition.

2. Boom angle indicator.

� Cranes with extendable booms must

utilize a boom angle indicator having“high and low” set points and audible/

visual alarm(s) capable of activating

function cutouts.

b. Boom hoist and load line shall have power

lowering and raising and shall have an auto

matic brake which is applied when the applic

able control is in neutral, or when the anti‐twoblock device is actuated.

c. If the crane is equipped with a “free‐fall” hoist,

steps shall be taken to ensure its use is not

possible during the use of the work platform.

(Note: A.P.I. applications do not permit the

crane to be equipped with free‐fall.)d. Each crane shall have a mechanical swing

park brake or swing lock capable of being set

at any swing position, and shall have a variable

swing brake or swing controls capable of stop

ping the upper swing motion smoothly. The

swing brake must be properly maintained at all

times to ensure its holding capability.

Operator's Manual


Note: All operational aids and equipmentmust be maintained in operable condition.Alternative measures are not permitted.

Crane Test ProceduresThe test procedures listed below shall be conducted at

the following intervals:

� Daily,

� At each job site before hoisting employees,

� After any repairs or modifications to the equipment,� When an operator is replaced, and

� When, in the judgement of responsible job site man

agement, or controlling entity, there has been a signi

ficant change in the conditions of the personnel lifting

operation.

Note: No personnel are allowed to ride the workplatform during any of the tests recommended in

this Section.

1. The work platform and rigging shall be proof tested

to 125 percent of the work platform's rated capa

city. (The proof test may be done concurrently with

the trial lift by completing the following test procedures.) Do not exceed the rated lifting capacity of

the applicable lift crane as listed on the crane capa

city charts. (Refer to ANSI A10.28 for suspended

work platform testing and inspection.)

a. This test load shall be tested for stability.

� The operator and signal person shall con

duct this test.� This test shall include movement of the work

platform through its entire intended range of

motion, simulating the specific operation to

be undertaken.

� A successful stability test must not produce

instability of the crane or cause permanentdeformation of any component.

b. This test load shall be raised and lowered atmaximum power controlled line speed (NOT

FREE‐FALL). The acceleration must be

smooth and the deceleration capability of the

control/braking system shall be confirmed by

bringing the work platform to a smooth stop.

The work platform shall be held in a suspen

ded position for a minimum of five minutes withthe test load evenly distributed on the work

platform. (This experience is intended to

sharpen the skill of the operator in handling the

work platform and to give the operator an op

portunity to evaluate the crane's perform

ance.) The work platform shall then be inspected for any evident sign of damage or defect.

2. All limiting and warning devices shall be tested by

activation of each appropriate control function.

3. With pinning and latching style extendable booms,

a visual inspection shall be conducted to verify that

the boom extend pins are properly set in the exten

ded boom sections.4. At the beginning of each lift, the work platform must

be hoisted a few inches (mm) with the personnel

and materials/tools on board and inspected by a

competent person to ensure;

� The work platform is secure and properly balanced,

� All wire ropes are free of deficiencies such askinking, crushing, corrosion, etc.,

� Any multiple part lines are not twisted,� The primary attachment is centered over the

work platform, and� If any load wire rope is slack, it must be inspected

to ensure that all wire ropes are properly seatedon the drum and in the sheaves.

5. Any condition found during any of these tests/in

spections that fails to meet requirements or may

create a safety hazard, must be corrected before

hoisting personnel.

Operation And Safety1. This Operator's Manual for the crane shall be read

and fully understood by operating personnel. This

Crane Operator's Manual shall be available to

them at all times.

2. Safety when handling personnel remains the full

responsibility of job site management and is de

pendent upon the responsible action of every person on the job involved in the related work.

3. Mobile lift cranes shall be erected to obtain maxim

um crane stability. The crane must be level and on

firm ground. It is recommended that the outriggers

be fully extended and the tires must be clear of the

ground before beginning any operation.4. The operator shall not leave the operator's station

when the work platform is occupied. The operator

shall remain alert in a position of readiness at the

work station with the engine running and the mas

ter clutch engaged, if crane is so equipped.

5. Unauthorized personnel shall not be in the cab(s)on the lift crane, or near the lift crane while a work

platform is suspended from the load line.

6. Any operation in which a work platform is to be sus

pended from the load line shall be carefully

planned by the operator, supervisory personnel,

designated signal person, and personnel to be lif

ted prior to commencement of such operation.They are to be advised:

a. That the crane does not have safety devices

normally used on personnel handling equip

ment.

b. That the safety of the operation depends on

the skill and judgment of the crane operatorand others present.

c. Of procedures to enter and leave the work plat

form and other safety procedures.

7. After positioning of the work platform:a. All brakes and locks on the lift crane shall be

set before personnel perform any work.

b. With pinning and latching style extendable

booms, a visual inspection shall be conducted

to verify that the boom extend pins are properly

set in the extended boom sections.

8. Telescope operation is not recommended with anyextendable boom with personnel in a suspended

work platform.

9. A work platform attached to load line of lift cranes

shall not be used for working on any energized elec

tric power line, or any energized device or facility

used for electric power generation or transmission.Minimum working clearance shall be at least twice

that recommended for material handling operations

in ANSI B30.5b section 503.4.5 and ANSI B30.23.

10. The combined weight of the work platform, any at

tachment device, personnel, tools, and other

equipment shall not exceed 50% of the lifting capa

city of the applicable lift crane as listed on the cranecapacity chart. (Note: A.P.I. applications require

25% of lifting capacity as the limit.)

11. Use caution when utilizing pendant supported lat

tice jibs on tubular or angle booms as the jib can

drift backwards into the jib backstops under cer

tain conditions. This is most likely with short jiblengths with minimum jib offset and maximum

boom angle. Pay special attention to detect the

possibility of jib drift during the work platform test

lift. An additional test lift is recommended with an

empty work platform when operation at or near

these conditions.12. The following actions and operations are strictly

prohibited when working with personnel suspen

ded in a work platform:

Operator's Manual


a. Cranes shall not travel while personnel are inthe work platform.

b. No lifts shall be made on another of the crane's

load lines with personnel suspended in a work

platform.

c. No external load is allowed to be lifted by at

taching it to the work platform.

d. Work platform lifts shall be a single crane operation. A work platform shall not be lifted using

g. Free‐fall (if equipped) shall not be used.

13. Movement of the work platform with personnel

shall be done in a slow, controlled, cautious man

ner with no sudden movements of the crane or

work platform. Do not use high speed functions, ifequipped.

14. Do not use multi‐function crane operation. If load

hoist, boom hoist, and swing functions must be

used to position the work platform, perform each

function individually.

15. Clear, unobstructed visibility between personnelon the work platform and the crane operator shall

be maintained at all times except where a desig

nated signal person has been assigned and posi

tioned such that he is visible to both. Such desig

nated signal person shall have no other duties to

perform when personnel are in the work platform.16. Voice communication between work platform per

sonnel, the crane operator, and designated signal

person, if assigned, shall be maintained.

17. If other cranes or equipment may interfere with the

lifting of personnel, signals or other means of com

munication between all crane or equipment oper

ators shall be maintained to avoid interference withindividual operations.

18. If the work platform is not landed, it shall be tied to a

structure before personnel mount or dismount the

work platform.

19. Personnel in the work platform shall wear personal

fall arrest systems. Anchors used for attachment ofpersonal fall arrest equipment shall be independ

ent of any anchors being used to support or sus

pend work platforms. Personnel shall keep all

parts of body, tools, and equipment inside work

platform during raising, lowering, and positioning.

20. Personnel shall always stand firmly on the floor of

the work platform and shall not sit or climb on theedge of the work platform or use planks, ladders,

or other devices for attaining a work position. (Thisdoes not apply to offshore personnel transfer bas

kets. Personnel must ride on the exterior of this

type of personnel handling device to assure great

er safety of the operation.)

21. When welding is done by personnel in the work

platform, the electrode holders shall be protected

from contact with metal components of the workplatform. If electrically connected electrode hold

ers contact work platform, work platform could be

dropped due to burning/melting of wire ropes sus

pending the work platform.

22. A pre‐lift meeting must be conducted with the

crane operator, signal person, employee(s) to behoisted, person responsible for the task to be per

formed, and anyone else that is directly involved

with the lift (as applicable) to review all the require

ments and procedures that must be followed to

complete the lift.

23. Follow all procedures for determining the rated ca

pacity and perform all testing as outlined in thisCrane Operator's Manual, the Crane Rating Manu

al, and all other Safety Manual(s).

Additional Requirements For Offshore Cranes1. Link‐Belt offshore cranes are designed to handle

materials. However, due to the special conditions

commonly existing offshore, the use of cranes totransfer personnel between vessels or from a ves

sel to a work platform is an established practice.

The safety of the personnel, if a materials handling

crane is used in transferring personnel, depends

upon the skill and judgment of the crane operator

and alertness of the personnel being transferred.Sea and weather conditions may create additional

hazards beyond the skill of persons involved.

This operation is approved by the American Petro

leum Institute (A.P.I.). By adopting procedures for

this operation, the institute has determined that the

transfer of personnel may be performed safely un

der certain offshore conditions. Therefore,whenever an offshore crane is used to transfer per

sonnel, all persons involved in the operation must

know and implement the A.P.I. procedures and

verify that sea and weather conditions are within

safe limits for the transfer.

In addition to all previous requirements in these Instructions, A.P.I. 2C requires the following:

� Boom and load hoists used shall be approved bythe hoist manufacturer for personnel handlingand shall be so indicated on their name plate.

� Refer to A.P.I. 2C Section 6 for further details andprocedures.

WARNINGRead and understand all “Operating Safety”instructions in this Operator's Manual before

attempting to operate the crane. This crane

should only be operated by a qualified

operator who has read and understood this

entire Operator's Manual.

Engine Throttle Controls

A throttle pedal may be located on the cab floor to provide the operator with flexibility of throttle operation.

Refer to Figure 1-39 Press down to increase engine

speed; release to decrease engine speed. Engine

speed is registered on a tachometer located in the LML

Display.

A grip throttle controller is incorporated into the swingcontrol lever located to the left of the operator's seat on

the control console. Refer to Figure 1-49. With the

throttle lock switch in the position, turn the grip

throttle counterclockwise to increase engine speed. To

reduce engine speed turn the grip throttle clockwise.

Operator's Manual


Throttle Lock Switch

While running the engine at the most optimum

constant speed, the crane operation speed is con

trolled by changing the hydraulic pump flow rate with

the grip throttle. This operation method is used when

increasing the work volume in duty cycle applications

with the engine speed running at a constant speed.

CAUTIONDo not start engine with the throttle lock switchin the position. If the engine is started withthe throttle lock switch in the position, theengine will start at the previously set enginespeed which may damage the engine and/or thepumps. Always move the throttle lock switch tothe position and turn the grip throttleclockwise (deceleration) to the limit of its travelbefore shutting down the engine.

1. To lock the throttle, press the throttle pedal or turnthe grip throttle until the desired engine speed is

reached. Engine speed is registered on a ta

chometer located in the LML Display.

2. Move the throttle lock switch to the position to

memorize the desired engine speed. The grip

throttle will still work like normal to operate the engine speed and the pump displacement.

3. To lock the throttle at the desired speed that was

memorized, move the throttle lock switch to the

position. Now the grip throttle controls only the

pump flow rate.

4. To increase operation speed, slowly turn gripthrottle counterclockwise. Crane operating speed

increases due to increase in the hydraulic pump

flow rate.

Note: With the low drum speed lock switch in

the position, the hydraulic pump control is

fixed at maximum to give fine inching control.

5. To decrease operation speed, slowly turn gripthrottle clockwise. Crane operating speed de

creases due to decrease in the hydraulic pump

flow rate.

6. Move the throttle lock switch to the position

and turn the grip throttle clockwise (deceleration)

to the limit of its travel before shutting down the engine.

To operate the crane similar to a conventional Link‐Belt

crane which does not contain a grip throttle, perform

the following operations.1. Set the engine speed at a slow rpm (just above an

engine idle speed) with either the grip throttle or

the foot throttle.

2. Memorize this engine speed by moving the throttle

lock switch to the position.

3. Lock the grip throttle at this engine speed by moving the throttle lock switch to the position. This

will set the engine speed at the memorized engine

rpm. The grip throttle will no longer control the en

gine speed however the grip throttle will still control

the pump flow rate.

4. Move the grip throttle counterclockwise to in

crease the pump flow rate to the desired operationspeed.

5. Control of the engine speed is still possible by us

ing the throttle pedal. Proceed to run the crane in

the conventional crane mode by using the throttle

pedal to control engine speed.

Boom Hoist Operation

Raising and lowering the boom is controlled by theboom hoist control lever. An automatic brake is incor

porated into the system which remains applied any

time the boom hoist control lever is in the neutral posi

tion. Refer to Figure 1-50. An automatic drum pawl

lock is also incorporated into the boom hoist system.

The boom pawl lock automatically engages when the

boom hoist control lever is moved to the neutral position and disengages when moved out of neutral.

Pulling the boom hoist control lever back toward the

operator raises the boom. Pushing the control lever

forward lowers the boom. The speed at which the

boom moves can also be regulated by the engine

throttle controls.

Note: When the boom approaches the upper or low

er limit, it will automatically slow down. At this time

an audible alarm will sound intermittently. When the

boom reaches the upper or lower limit, it will auto

matically stop. At this time an audible alarm will

sound continuously.

To Raise The Boom1. Refer to the correct capacity chart in the Crane Rat

ing Manual for proper crane set up based on loadradius, working area, etc.

2. Check that the boom hoist drum lever lock is in theunlocked position.

3. Pull the boom hoist control lever back toward theoperator to raise the boom. If desired, increase theengine throttle to speed up the boom.

4. After reaching the desired boom angle, move theboom hoist control lever to the neutral position tostop the boom.

5. If the boom is not going to be moved for an extended period, move the boom hoist drum leverlock to the locked position to prevent inadvertentoperation of the control lever.

To Lower The Boom

1. Refer to the correct capacity chart in the Crane Rating Manual for proper crane set up based on loadradius, working area, etc.

CAUTIONWire rope may need to be spooled off the frontand/or rear winch drum(s) as the boom is

lowered. Failure to do so may cause two

blocking.

2. Check that the boom hoist drum lever lock is in theunlocked position.

Note: It may be necessary to raise the boom

slightly in order to release the drum pawl.

CAUTIONDo not lower the boom when boom hoist pawlin engaged as damage to the boom hoist drum

may result.

3. Push the boom hoist control lever forward to lowerthe boom. If desired, increase the engine throttleto speed up the boom.

Note: Do not lower a long boom at or near full

throttle. Control the lowering speed with the

boom hoist control lever. Half throttle or slightly

less is a good speed for lowering long booms.

4. After reaching the desired boom angle, throttledown and slowly move the boom hoist control leverto the neutral position to stop the boom.

5. If the boom is not going to be moved for an extended period, move the boom hoist drum leverlock to the locked position to prevent inadvertentoperation of the control lever.

Operator's Manual


Boom Hoist Limit Override OperationThe crane is equipped with a boom hoist limit system that

is used to prevent over hoisting the boom. When theboom reaches the maximum angle, a limit switch at the

base end of the boom is tripped which disables the boom

hoist function and prevents the boom from being raised

any further. An audible alarm will sound signaling the op

erator that maximum boom angle has been reached,

approximately 80.8�. Refer to Figure 1-51. The boomhoist limit switch should be checked and adjusted as

needed and anytime the boom base section is removed

and installed back on the crane. Refer to Section 4 of this

Operator's Manual for complete instructions.

The boom must be lowered in order to silence the alarm.

However, to release the boom hoist drum lock and lower

the boom, it may be necessary to raise the boom slightlyto disengage the boom hoist drum pawl. The Boom

Hoist Limit Override switch is then used to reactivate the

boom hoist function to raise the boom enough to release

the drum lock and lower the boom. The audible alarm will

continue to sound even after this switch is pushed. To

reset the boom hoist limit system, lower the boom untilthe boom hoist audible alarm is silenced.

Use the following procedure when using the override

switch:

1. Return all drum control levers to neutral.2. With the engine at idle, turn the Master Control

Override Key switch to the “ON” position.3. Hold the Boom Hoist Limit Override switch in the

“OVERRIDE” position.4. Slightly raise the boom, then slowly lower the

boom until the boom angle is less than 80.8°.5. Release the Boom Hoist Limit Override switch to

the “NORMAL” position.6. Turn the Master Control Override Key switch to the

“OFF” position.

Boom Backstop Limit OverrideOperationThe boom backstop limit system is designed to prevent

the boom from over hauling and damaging the boom

or backstops. When boom angle reaches approxi

mately 82.3°, the backstop limit switch, located on the

backstops, is tripped which disables the boom hoist

and lowering functions. To restore boom hoist and low

ering functions, the Control Pilot Pressure Overrideswitch must be used. Use the following procedure

when using the override switch:

1. Set the engine at idle and operate slowly.2. Turn the Master Control Override Key switch to the

“ON” position.

Note: The Master Control Override Key switch

may have already been moved to the “ON” position when the boom hoist limit switch was tripped.

6. Turn the Master Control Override Key switch to the“OFF” position.

Boom Lower Limit

When lowering the boom below the working radius

listed in the Crane Rating Manual, the boom lower limitis activated disabling the boom lowering and winch

hoist functions. At this point, the Guidance for erection

storage confirmation pop‐up screen is displayed on

the LML display. However, if the load factor is more

than 30%, the guidance screen will not be displayed. In

this case, the guidance for “The front attachment is outside the maximum working range. Retract the working

radius or ground the load.” is displayed and the erec

tion storage screen will not be displayed. Lower the

hook block and/or hook ball to the ground and/or raise

the boom to a working radius to restore boom lowering

and winch hoist functions.

WARNINGOperation under conditions which exceedlisted capacities may result in overturning.

Swinging or lowering boom to radii where no

capacities are listed may result in overturning

even without a load.

Operator's Manual


Figure 1-52Boom Angle Indicator

0

0

Boom Angle IndicatorA mechanical type boom angle indicator is mounted onthe base section of the boom to the left of the operator's

cab. Refer to Figure 1-52. It must be adjusted prop

erly, free from binding, and the crane must be level for

the unit to accurately indicate boom angles. Even un

der these conditions its readings are only approximate.

When making near capacity lifts, measure the load ra

dius to determine crane capacity. Check the adjustment of the boom angle indicator daily to ensure its ac

curacy. Refer to Section 3 of this Operator's Manual for

adjustment procedures.

Front And Rear Or 4th (If Equipped)Drum OperationRaising and lowering a load is controlled by the front

and rear drum control levers, drum pawl switches, and

drum brake mode switch. Front and rear drum brake

pedals are also used to control the load and operate

either manually or automatically. Refer to Figure 1-53.

WARNINGThe weight of the load must be known beforemaking a lift. Compare the load weight to the

appropriate capacity chart in the Crane Rating

Manual to ensure compliance with capacity

ratings. Compare the load weight to the Wire

Rope Capacity chart in the Crane Rating

Manual to determine the number of parts of

line required to lift the load. Rig and set up thecrane to ensure compliance with both the

crane capacity chart and Wire Rope Capacity

chart in the Crane Rating Manual.

The front and rear drum control levers have two speedsof operation in both raising and lowering mode. Mov

ing the control lever forward or backward engages the

1st speed of operation. As the control lever is moved

further, a 2nd and faster speed is obtained. The engine

throttle setting will also effect the speed of operation.

The brake system for the front and rear drums has two

modes of operation. Drum brakes can be selected tooperate in an automatic or manual mode. When the

brake free mode key switch on the left control panel is

in the “DISABLE” position and the brake mode switch

on the drum control lever is in the “AUTO” position, the

drum brake applies automatically any time the control

lever is in the neutral position. When the brake freemode key switch on the left control panel is in the “EN

ABLE” position and the brake mode switch on the

drum control lever is in the “FREE” position, the drum

brake must be manually applied using the brake ped

al(s) on the cab floor.

Note: When the brake free mode key switch is in the

“DISABLE” position, free mode cannot be activatedeven if the selector switch on the drum control lever

is in the free mode position.

The following general procedures give instructions for

raising and lowering the load based on the the type of

brake system used. However, variations in load and

job site conditions may require adaptations to thesegeneral procedures. Crane operations are to be per

formed only by a qualified operator who has read and

fully understands the entire content of this Operator's

Manual.

Operating In “AUTO BRAKE” Mode

1. Refer to the Crane Rating Manual for proper craneset up based on load radius, working area, etc.

2. Position the head machinery directly above theload. Connect the hook block or hook ball to theload.

3. Fully apply and latch the drum brake foot pedal onthe cab floor.

4. With the engine at idle, move the brake free modekey switch on the left control console to the “DISABLE” position.

5. Check that the drum pawl switch is in the position. (The drum pawl will ratchet allowing the loadto be lifted.)

6. Move the drum brake mode switch on the controllever to the “AUTO” position. Check that the redfree mode indicator light on the brake mode indicator panel is off and the green auto brake mode indicator light is on.

Operator's Manual


To Swing The Upper1. Compare the boom configuration and length to the

appropriate capacity chart in the Crane RatingManual. Position the boom safely within the limitsspecified on the capacity chart in the Crane RatingManual.

DANGERAll personnel and equipment must be out ofthe path of the rotating upper. Failure to do so

will result in severe personal injury or major

equipment damage.

Swing slowly and cautiously. Watch out for

centrifugal force. Out swing of a load

increases the load radius and thus decreases

capacity. Load out swing may result in tippingor damaging the crane.

2. Disengage the travel swing lock using the controlpedal below the operator's seat.

Note: In order to disengage the travel swing

lock, it may be necessary to swing the upper

slightly in one direction or the other to ease the

eration. The travel control system employs a two

speed travel which can be utilized to provide the opera

tor with two speeds of crane travel. Place the travel

high speed switch located on the left overhead controlpanel in the position for high speed and in the

position for standard speed. Travel speed is pro

portional to lever movement and throttle position. The

travel brakes are a spring applied, hydraulically re

leased multiple disc type which are automatically ap

plied when the travel/steer levers are returned to theneutral position. When not traveling the crane, use the

travel lever lock to prevent inadvertent operation of the

travel levers. To travel and steer the crane along a firm,

level route, proceed as follows:

Note: The following instructions are based on trav

eling the crane with the travel motors to the rear.When the travel motors are in front, the right and left

travel/steer lever operations must be reversed.

1. Always take time to choose the safest, most levelroute. Designate a signalman to guide the operator along the route.

2. Position the upper directly over the end of the lowerand engage the travel swing lock.

Operator's Manual


Operating In Wind And

LightningAvoid working a crane in high winds and when there isa liklehood of lightning. Rated lifting capacities do notaccount for the effects of wind on a suspended load orboom. Lifting capacities should be considered acceptable for wind speeds up to 20 mph (32km/h) and appropriately reduced for wind speeds greater than 20mph (32km/h). If you must work in a wind, reduce capacities to those listed in the “Wind Speed” chart andall restrictions outlined in the “Wind Restrictions Guide”located in the Crane Rating Manual. Wind blowingagainst the load and the boom produces a side load onthe boom and reduces its capacity. When lifting loadswhich have large surface areas in a wind, such asbuilding panels, the movement of the load may pose a

danger to workmen or building structures. Out swingof a load will increase the load radius, and may overload the crane. This could lead to boom failure or thecrane tipping. Monitor the wind speed using a windspeed indicator. Stop lifting operations, ground theload, and lower the boom to the ground if wind speedexceeds the maximum allowed listed in “Wind Speed”chart in the Crane Rating Manual. Use the followingtable as a general guide.

DANGERIf there is a likelihood of lightning,immediately stop lifting operations, ground

the load, and fully retract and lower the boom

in the boom rest.

Operator's Manual


Load Moment LimiterThe following describes the function and operation of

the Load Moment Limiter (LML). The system is in

tended to aid the operator in the efficient operation of

the crane by continually monitoring the load and warn

ing of an approach to an overload or unsafe condition.

WARNINGAlthough the system will alert the operator ofan approaching overload or unsafe condition,

it remains the responsibility of the operator to

operate the crane safely at all times.

This system must never be substituted for the

good judgment of the crane operator using safe

operating procedures. The operator is solely

responsible for safe operation of the crane.

!!THIS SYSTEM IS AN OPERATOR'S AID -

NOT A SAFETY DEVICE!!

System Description

The system monitors crane functions by means of

high accuracy sensors and continuously compares

the load with a copy of the crane capacity chart

which is stored in the computer memory. If an over

load or unsafe condition is approached, the systemwarns by means of audible and visual alarms. Func

tion limiters will also activate under certain conditions

to limit crane movement.

The Load Moment Limiter provides the operator with

a continuous display of:� Rated Load or Radius of Load

� Actual Load

� Percentage of Rated Capacity

� Angle of the Main Boom

� Crane Configuration

� Length of the Main Boom� Jib Angle, Jib Offset, or Radius of Jib Load

An additional feature of the system is the provision of

operator settable alarms. These alarms, when prop

erly set, provide a method of obstacle avoidance.

This is achieved by means of minimum and maximum boom angle, minimum and maximum radius,

and maximum height. These alarms can be pro

grammed for each job site and set rapidly for the

prevailing site conditions thereby aiding the operator

in safe operation of the crane.

Precautions For Safe Operation

WARNINGThe limiting and monitoring devices areimportant to assist in safe crane operation.

Always check that these devices operate

correctly and use them during operation.

Improper operation, intentional deactivation,

and insufficient inspection and/or

maintenance of the these devices may cause

serious accidents and major damage to, ortipping of the crane. If a limiting and/or

monitoring device malfunctions, immediately

repair it. Operate the crane only after making

repairs or follow procedures in “System

Inoperative Or Malfunctioning” in this Section

of this Operator's Manual.

1. To correctly operate the limiting devices, check

them at regular intervals according to the instruc

tions described in this Operator's Manual.

2. Do not attempt to modify the limiting devices.

3. If a limiting device does not operate correctly, stop

the crane and make necessary repairs. If repairscannot be made, follow procedures in “System In

operative Or Malfunctioning” in this Section of this

Operator's Manual.

4. Do not operate the crane with the limiting devices

deactivated. If intentionally deactivated, the crane

may be overloaded, resulting in a serious accident.

5. Observe the following points to accurately operatethe load moment limiter.

a. Correctly install the boom hoist drum wire rope

and the winch wire ropes.

b. The maximum load ratings are designated de

pending on the length of the boom and the jib

to be used. Be sure to use the correct parts ofline and the hook size corresponding to the

maximum load rating.

c. Grease the boom foot pins, live mast foot pins,

and boom hoist bail at regular intervals. Suffi

ciently grease before storing or re‐using the

crane.

d. Before operating the crane, be sure to extendthe side frames unless the retracted side frame

capacities are being used.

System Operation

The following is a list of procedures which are used

to operate the multiple features of the LML. Use

these procedures in conjunction with the previous

display unit control descriptions.

System Inoperative Or Malfunctioning

When operational aids are inoperative or malfunction

ing, the following recommendations for continued use

of the crane should be followed or the crane should be

shutdown.

1. Steps shall be taken to schedule repairs and recal

ibration immediately. The operational aids shall beput back into service as soon as replacement

parts, if required, are available and the repairs and

recalibration can be carried out. Every reasonable

effort must be made to expedite the repairs and re

calibration.

2. When the LML is inoperative or malfunctioning, thedesignated person responsible for supervising the

lifting operations shall establish procedures for de

termining load weights and shall ascertain that the

weight of the load does not exceed the crane rat

ings at the radius where the load is to be handled.3. When a boom angle or radius indicator is inopera

tive or malfunctioning, the radius or boom angle

shall be determined by measurement.

4. When the anti‐two block warning device is inopera

tive or malfunctioning, the designated person responsible for supervising the lifting operations

shall establish procedures, such as assigning an

additional signal person, to furnish equivalent

protection. This does not apply when lifting per

sonnel in load line supported baskets. Personnel

shall not be lifted in load line supported basketswhen the anti‐two block devices are not function

ing properly.

5. When a level indicator is inoperative or malfunc

tioning, other means shall be used to level the

crane.6. In situations where inconsistency exists, verified

weights, measured radii, boom lengths, and au

thorized crane capacities must always take prece

dence over indicator readings.

Menu Pop‐Up Screen

After the system is started and the crane configurationis confirmed, the ML screen (normal working screen) is

displayed. If a setting change is required, use the

Menu Pop‐Up screen. Access this screen by pressing

the decide button from the ML screen. Six screens

can be accessed. Use the following instructions to op

erate menu screens.

Note: All screens shown are samples to explainhow to operate them. Therefore, some of them may

differ from those actually displayed.

CAUTIONIf the crane configuration is not inputcorrectly, the ML functions may not work

properly, possibly resulting in tipping over or

damage to the crane. Ensure that the input

crane configuration matches the actual crane

configuration.

If the crane configuration does not match with the dis

played ones, perform the following operation. During

this operation, all crane operations are automatically

stopped.

Anti‐Two Block Limiting Device

The anti‐two block system is an electromechanical

system designed to alert the operator before the

hook block, hook ball, or load contacts the head

machinery of the main boom or jib. When a two

block situation is imminent, an audio/visual alarm is

activated to alert the operator of the pending danger.

When the alarm activates, it is essential that theoperator discontinue operations immediately, and

correct the two block situation.

CAUTIONDo not allow the load to spin out of controlwhen hoisting. The anti‐two block weight may

become entangled with the wire rope and

could damage the anti‐two block system, wire

rope, or boom. It is recommended to use

rotation resistant wire rope during single part

of line hoisting applications, especially when

long fall lifts are involved.

Three basic components are used to make up the anti‐two block system. The anti‐two block weight and head

machinery switch, located at the head machinery (refer

to Figure 1-64), and the audio/visual alarm in the op

erator's cab.

An anti‐two block weight is suspended from each of the

head machinery switches and is used to hold the

switch in the off position. When the anti‐two block

weight is lifted by the hook block, hook ball, or load itallows the switch to activate the audio/visual alarm in

the operator's cab. In addition to the audio/visual

alarm, function limiters are activated.

The added feature of hydraulic function limiters prevent

the operator from continuing crane functions which will

cause a two block situation to occur. The crane func

tions of winch up and boom down are disabled when

Operator's Manual


Figure 1-66Backstop Limit Switch

Backstop Limit Switch

(right side)

the anti‐two block weight is lifted. These functions will

remain disabled until the two block situation is cor

rected or the override switch is utilized.

The main boom head must always have a head ma

chinery switch. If wire rope is reeved on the main boom

head, it must also have and anti‐two block weight.

Each of the added attachments used on the crane

must employ a head machinery switch, proper cable

connections, and weight in order for that particular attachment to be monitored by the system.

Check that all the harness connections are properlyjoined and test the system before beginning operations. Test the system by manually lifting the ATBweight and verifying that the function limiters activate toprevent winch up and boom down.

Backstop Limiting Device

CAUTIONThis device is very important to assist in safecrane operation. Always check that this

device operates correctly and use this device

during operation. If this device malfunctions,

immediately repair it. Operate the crane only

after repairing the malfunction. Do not

attempt to modify this device. If any problem

occurs, contact your Link‐Belt Distributor.

The backstop limiting device is designed to prevent the

backstops from becoming rigid. When the boom angle

exceeds 82.3 degrees, the backstop limit switch on the

boom backstop sends a signal to the controller. (Refer

to “Boom Backstop Limit Switch Adjustment in Section

4 of this Operator's Manual for adjustment proced

ures.) The controller then deactivates the boom hoist,front, rear, and third drum functions and sounds the

alarm. However, when the control pilot pressure over

ride switch is operated, only winch down of each drum

becomes operable.

Note: The backstop limit switch cannot be overrid

den in the boom hoist direction. The switch must beadjusted to activate before the backstop springs

become solid. If the backstop limit switch is acti

vated due to overhoist of the boom, use the control

pilot pressure override switch to lower the boom

and deactivate the function limiter.

WARNINGDo not adjust backstop limit switch with the jibinstalled. Live mast may overhaul the boom

causing major crane damage and/or serious

personal injury. Remove the jib before adjust

ing the backstop limit switch.

Check that all the harness connections are properlyjoined and test the system before beginning operations. Test the system by manually activating theswitch (access the switch through the slot in the switchcover) and verifying that the function limiters activate.

Entering And Exiting TheOperator's CabEntering or exiting the operator's cab could be hazard

ous if certain aspects are not taken into consideration.

The elevation of the lower frame alone could cause serious injury from a fall. For this reason steps are

mounted on each side of the lower to provide easy ac

cess to the operator's cab. Numerous hand grips are

also attached to the operator's cab to provide safe en

try to the cab. Remain in three point contact with the

crane at all times (two hands and one foot or two feet

and one hand). Use these features to make climbingon the crane as safe as possible.

Gate Lock Lever

The gate lock lever is located at the lower right front of

the operator's cab. Refer to Figure 1-68. When oper

ating, pull the gate lock lever to the “Operation” posi

tion. Push the gate lock lever up to the “Stop” position

when waiting in the operator's cab or entering or exit

ing the operator's cab. When the gate lock lever lever

is pushed to the “Stop” position, the pilot oil pressuredrops to zero and all functions are stopped. If a control

lever is activated, the crane will not function with the

gate lock lever in the “Stop” position. To start opera

tions, after making sure all control levers are in the

“neutral” or “lock” position, pull the gate lock lever

down to the “Operation” position.

WARNINGThe gate lock lever should not be placed in the“Stop” position when operating the crane.

Note: If gate lock lever is moved to the “Stop” posi

tion and back to the “Operation” position while op

erating in free mode, drum free mode indicator light

will begin to flash. If this occurs, drum brake will au

tomatically change to auto brake mode. To return to

free mode, latch drum brake pedals and move drumbrake mode control switch to “Auto” position and

back to “Free” position. Indicator light should stop

flashing and remain illuminated.

should carefully read and understand the engine start

ing instructions in the engine manufacturer's manual

and this Operator's Manual. Attempting to start or run

the engine before studying these instructions may re

sult in engine damage. With crane fully serviced andthe operator familiar with all gauges, switches, and

controls and having read and fully understood this en

tire Operator's Manual and the entire engine manufac

turer's manual, start the engine using the following pro

cedures:

WARNINGDiesel exhaust fumes can beharmful. Start and operate

engine in a well ventilated area.

If it is necessary to operate in an

enclosed area, vent the exhaust

to the outside. Properly

maintain the exhaust system toits original design.

To Start The Engine1. Walk around the crane to verify that there are no

persons under, or in close proximity of the crane.

2. Check that the crane gate lock lever is in the

“STOP” position and all control levers are in the

neutral position with the lever locks engaged to

prevent inadvertent operation of the crane.3. Check that the throttle lock switch in the posi

tion.

Operator's Manual


General OperationThe following procedure contains helpful information

for typical lift crane operation. This information is gen

eral in nature and is not intended to serve as a fail safe

procedure for any and all situations. The operator

must, at all times, be alert and fully aware of the load

requirements and specific job site conditions. The operator must be ready and able to perform any change

in procedure, in a moments notice, to safely operate

the crane as the immediate situation changes.

Lift Crane OperationCranes are used primarily for making heavy lifts. In or

der to do this properly, certain procedures must be followed. The following is a suggested procedure for

making typical lifts:

1. Determine the weight to be lifted. Be sure to add theweight of the hook block and/or hook ball, slings, rigging, jib, etc. Determine height to which the loadmust be lifted.

2. Refer to the Working Areas, Working Range, andthe appropriate capacity chart in the Crane RatingManual. Find the shortest boom length and loadradius that will accomplish the job and assemblethe crane accordingly.

3. Position the crane so a minimum swing is necessary.4. The crane must be supported by a firm, level sur

face before starting to lift. All capacities on the capacity charts in the Crane Rating Manual are basedon the crane being level in all directions. If thecrane is not level, out swing or side swing of theload will greatly reduce lifting capacities and couldcause crane damage or an accident. If the groundis soft, use mats to prevent crane from sinking intothe ground.

5. Check that the proper counterweight arrangementis properly installed. Do not make lifts which exceed capacity chart specifications.

6. Check that the correct configuration has been entered in the Load Moment Limiter.

7. Raise the boom and swing over the load.8. Lower the hook block and/or hook ball and fasten it

to the load. The following points must be observed:a. The boom peak must be directly above the

load. (Booms are made to lift, and shouldnever be used to drag a load sideways.)

b. Always use chains, wire ropes, and/or slings ofample size and make periodic checks of theircondition.

c. Always use sufficient parts of line. Refer to the

Wire Rope Capacity chart in the Crane Rating

Manual for the number of parts of line needed

for a given lift.

d. When lifting loads, care should be taken to prevent sudden loading or unloading of the winch

wire rope. Ease into the load. Lift the load a

few inches (centimeters) off the ground and

hold to check the winch brakes.

9. Lift the load to the desired height. Boom to the de

sired angle. Be careful when booming down or

swinging the load, as these increase the load radius and result in a decrease in capacity. Make

sure the load being lifted remains within the lifting

capacity of the crane for the boom length, radius,

and working area being used.

10. Control the load at all times. Use hand lines to

guide the load. Do not guide loads into place withyour hands. Swing slowly and smoothly. Avoid

jerks when starting or stopping swings.

Operator's Manual


Dragline Operation

With the bucket lowered in digging position pull the

front drum control lever to pull the bucket toward the

crane. Regulate the depth of cut by dragging the rear

drum brake or hoisting the rear drum. As the bucket

fills, release the front drum control lever and apply both

brakes to hold the bucket and keep it from unloading.

Begin hoisting the loaded bucket by engaging the rear

drum control lever and simultaneously releasing both

the front and rear drum brake pedals. However, a slight

drag on the front drum brake is required to balance the

bucket. Once the bucket is to the desired height, fully

apply both drum brakes.

Swing to the desired location and slowly engage theswing control lever in the opposite direction to that

which started the swing in order to slow and then stop

rotation of the upper. Dump the load by releasing the

front drum brake.

Swing the upper back to the digging spot by actuating

the swing control. Stop the swing at the desired location by slowly engaging the swing control lever in the

opposite direction to that which started the swing in or

der to slow and then stop rotation of the upper. Lower

the bucket to the ground by gradually releasing both

drum brakes.

Operating Tips For Dragline Operation

1. Refer to the the Working Areas, Working Range,

and the Duty Cycle capacity charts in the Crane

Rating Manual. Do not exceed the ratings listed in

the Crane Rating Manual.

2. Do not use the jib for dragline or any other type of

duty cycle application.

3. Check that the correct configuration has been input in the LML.

4. The side frames must be extended.

5. Select the right size bucket for the size of the crane

and the type of material being excavated. Effective

use of a dragline is dependent upon an efficient cy

cle of digging, hoisting, swinging, and dumping.The power of the crane to accomplish this, plus the

weight of a loaded bucket, the proper laggings,

and the length of boom must all be taken into ac

count when determining bucket size.

6. Keep the bucket teeth sharp and tightly mountedfor efficient digging.

7. Inspect the drag chains periodically, paying par

ticular attention to the end links. It may be possible

to extend chain life by reversing it end for end or top

to bottom.8. If bucket fails to dig properly, adjust chain hitch.

9. Keep the dump line adjusted. When the dump line

is too long, the bucket must be pulled up close to

the fairleader to keep it level. Too long a dump line

causes the bucket to dump before it gets out under

the boom peak minimizing reach.10. Work with the boom at the highest angle that will

allow the reach and accuracy needed for the job. A

low boom (35° to 40°) gives a longer reach and

better control of the bucket throw along with more

accurate grading and dumping. A high boom (45°to 50°) increases stability and decreases swing

loads and swing power requirements.

Note: Dragline operation with boom angles of

less than 35° is not recommended.

11. Keep the crane close enough to its work to eliminate digging beyond the boom point as much as

possible and reduce unnecessary casting and

hoisting.

12. Slice material off in layers. In ditch excavation, re

move the sides or slopes before the center to keep

the ditch from narrowing and to prevent using theswing system to hold the bucket against the

banks.

13. Use a short haul. Hoist the bucket when it is full.

After the bucket is full, no more material may be

loaded no matter how far it is pulled.14. Move back and dig off top edges that may wear or

cut the in‐haul wire rope. Avoid piling dirt under the

boom foot. Piling dirt under the boom foot wastes

time and power and makes a “wear trap” for the in‐

haul wire rope.

15. Keep the bucket as far from the boom as possiblewithout spilling the load. This will reduce wear on

wire ropes and clutches and will also minimize

bucket and boom damage.

16. Don't pull the in‐haul wire rope socket into the

fairleader. Keep the dirt and mud cleaned off the

fairleader to prevent wear on in‐haul wire rope andfairleader.

17. Don't drop the bucket to stop swing of the upper.

Don't bang the bucket against banks or truck bod

ies to knock out sticky mud. Don't drop the bucket

in a heap as the chains and wire ropes may become entangled.

18. Boom length for dragline work should not exceed

the values listed in the Crane Rating Manual.

Clamshell Operation

The following procedure is written as though the open/

close winch line is rigged to the rear drum. This line

does not have to be on the rear drum. The front and

rear drum winch lines may be rigged to satisfy the op

erator.

With the bucket in digging position, engage the reardrum control lever while simultaneously releasing the

rear drum brake, to fill and close the bucket. As the

bucket closes, engage the front drum control lever

while simultaneously releasing the front drum brake to

hoist the bucket. When the bucket reaches the desired

height, fully apply both brakes and release both control

levers.

Swing to desired location and gradually engage the

swing control lever in the opposite direction to that

which started the swing to slow and then stop rotation

of the upper. Dump the load by releasing the rear drum

brake.

Swing the upper back to the digging spot by actuatingthe swing control. Stop the swing at the desired loca

tion by gradually engaging the swing control lever in

the opposite direction to that which started the swing to

slow and then stop rotation of the upper. Lower the

bucket to the ground by gradually releasing both drum

brakes.

Operating Tips For Clamshell Operation1. Refer to the Working Areas, Working Range, and

the Duty Cycle capacity charts in the Crane Rating

Manual. Do not exceed the ratings listed in the

Crane Rating Manual.

2. Do not use the jib for clamshell or any other type of

duty cycle application.3. Check that the correct configuration has been in

put in the LML.

4. Move the tagline switch on the left overhead con

trol console to the correct position.

5. The side frames must be extended.6. Select the right size bucket for the size of crane and

the type of material being excavated. Effective use

of a clamshell is dependent upon an efficient cycle

of digging, hoisting, swinging, and dumping. The

power of the crane to accomplish this, plus theweight of a loaded bucket, the proper laggings,

and the length of boom must all be taken into con

sideration when determining bucket size.

7. Lift the bucket as soon as it fills. Start to swing as

the bucket is lifted to save time on digging cycle.

8. Keep a tight closing line while hoisting. Do not release the closing line while the bucket is being

raised or the bucket will open too soon.

Operator's Manual


9. When returning to the digging position with thebucket open, do not tighten the closing line or the

bucket will close in mid air.

10. Match the lengths of closing and holding wire

ropes. This is particularly necessary in deep dig

ging which requires spooling of more than one lay

er on the drums. With properly matched wire ropelengths, both the closing and holding lines will start

the second layer at the same time and provide

smooth operation.

11. Attach tagline to hold bucket in‐line or crosswise to

the boom, whichever will give best control of thebucket placing and dumping for job condition.

12. When lowering bucket into deep trenches where it

cannot be seen, use a signalman to advise of

bucket position. Lowering bucket closed andopening it on signal is sometimes advisable be

cause it affords greater clearance.

13. Each bucket manufacturer recommends the parts

of line to reeve the bucket for digging various mate

rials. In general, loose flowing materials require

fewer parts of line for faster closing. For harder materials or digging, increase the number of parts of

line. Add the recommended bucket counterweight

for better bucket penetration and digging.

14. Don't bang the bucket to release sticky material.

Close bucket and release closing line quickly toshake material loose.

15. Boom length and boom angle for clamshell work

must not exceed the values listed in the Crane Rat

ing Manual.

Front Mounted Third Drum

WinchA third drum may be mounted on the front of the upper

frame between the boom foot. Refer to Figure 1-82.

Although there are other applications, the front

mounted third drum can be added to optimize the operation of pile driving. It is used where the third drum

wire rope is reeved over the boom point and left at

tached to the piling as it is being driven by the hammer.

The front mounted third drum is controlled by the third

drum control lever (Figure 1-54). It has two modes of

operation, Automatic Brake Mode and Free Mode.

WARNINGThe front mounted third drum is not equippedwith a foot pedal and true free‐fall as are the

main winches. It cannot be used to free‐fall

loads. It cannot be used to lift a load unless it

is in the Automatic Brake Mode.

The Automatic Brake Mode allows normal operation ofthe winch, which matches the front and rear winch. It is

power up/power down with an automatic brake which

applies when the third drum control lever is in neutral.

The Free Mode allows the automatic brake to release.

In Free Mode the wire rope can be pulled off the drum

with a force of approximately 500 lb (227kg).

To operate the third drum for pile driving applications:1. With third drum in Automatic Brake Mode, attach

the wire rope to the pile.2. Using the third drum, hoist the pile into position un

der the hammer.3. Move the mode switch to the Free mode position.

Move the 3rd drum lever to the lowering position toactivate the free spooling function.

4. The pile will pull wire rope off the drum as it is driveninto the ground. This is advantageous to the operator because the drag on the wire rope is providedby the winch and the operator does not have toconstantly watch the third drum wire rope.

5. After driving the pile, return the lever to neutral andmove the brake mode switch to Auto mode beforehoisting another pile.

Operator's Manual


Traveling The CraneCertain conditions must be met for safe travel when

traveling with or without a load, or when traveling on a

slope. Use the following procedures when traveling

the crane.

Traveling Without A Load

The crane can be traveled with all boom lengths and allboom plus jib combinations as listed in the Crane Rat

ing Manual. Refer to the Crane Rating Manual for liftoff

capability and instructions. When moving the crane

around the job site with the attachment in the air, ob

serve the following precautions for safe job site travel.

1. Terrain must be smooth and solid. If not, grade thearea before moving the crane.

2. Tie down hook block and/or hook ball to prevent

them from swinging.

3. Position a signalman for guidance.

4. The boom must be positioned at a boom angle for

which a capacity is given in the Crane RatingManual. All other boom angles are considered out

of the allowable working range of the crane and no

travel is allowed

5. The boom should be positioned over the end of the

lower. Certain job site conditions will make this im

possible. Travel with the boom pointed over the

side will be allowed only when conditions preventtraveling with the boom straight over the end.

6. Engage the travel swing lock (upper positioned

over the end) and the swing park brake.

7. Travel slowly and cautiously in order to avoid any

shock loading on the boom or crane. Use the trav

el high speed switch to reduce travel speed if necessary.

Traveling With A Load (Pick & Carry)

All 360 degree capacities (except list and duty cyle ca

pacities) listed in the Crane Rating Manual are pick and

carry capacities. The following precautions must be

followed while traveling with a load.

1. Travel with the boom pointing straight over one end

of the lower. If the load was lifted over the side,swing the load over the end before starting travel.

2. Engage the travel swing lock and swing park

brake.

3. Travel only on a smooth, level surface. If a smooth,

level route is not available, don't travel with a sus

pended load. Grade the route to provide a smooth,

level path. If it is not possible to grade the route,move the load by stepping. Park the crane on a lev

el area, lift the load, swing around, and set it down

ahead of the crane. Travel the unloaded crane be

yond the load, level the crane, lift the load, swing,

and set it down farther along the route. Continue

this procedure until the load is at its destination.4. Use hand lines to control the load and reduce load

swing.

5. Carry loads as close to the ground as possible.

6. Do not allow side swing of load.

7. Don't attempt to carry loads which exceed the

crane's rating.

8. Use a signalman to warn of any danger or obstruction along the route being traveled.

9. Don't travel with a load on soft ground. If the crane

sinks into the ground, stability can be affected to

the point of tipping the crane.

10. Keep all personnel clear of the crane and load. Be

prepared to set the load down quickly at anytime.11. Position the boom at a boom angle that will give the

greatest margin of safety. If the load was lifted at a

long radius and the load is at or near capacity for

that radius, boom up to obtain a greater lifting ca

pacity (and thus a greater margin of safety) before

starting travel.12. Travel slowly and cautiously in order to avoid shock

loading on the boom or crane. Use the travel high

speed switch to reduce the travel speed if neces

sary. Do not let the load swing out or to the side.

The load must be kept directly under the boom

point at all times.

13. Use only the “360° Rotation” capacities listed in theCrane Rating Manual for traveling with a suspended load.

Operator's Manual


Traveling On A Slope (Without A

Load Only)

Travel on a slope is allowed up to a grade of 30%. The

following precautions must be followed.

1. When traveling on a slope, always face the upper

straight over one end of the lower.

2. Engage the travel swing lock and swing parkbrake.

3. Travel straight up or down the slope with the

“heavy” end of the crane facing uphill. The heavy

end of the crane will normally be the counterweight

end of the crane. With some long boom combina

tions, the boom end of the crane will be the “heavy”end. If possible, position the boom at a high

enough boom angle so that the counterweight end

of the crane is the “heavy” end of the crane and

travel with the boom facing downhill.

4. Always travel in a slow, cautious manner when trav

eling on a slope. Use the travel high speed switch

to reduce travel speed if necessary.5. Do not travel with a load on a slope. Severe boom

off lead and/or side load will result, which will great

ly increase the loading into the boom structure.

6. Watch the engine service monitor. Be alert to the

engine service monitor while traveling on a slope.

All lamps should be off under normal operation. Ifan engine service monitor lamp comes on while

traveling on a slope, the slope is too great for the

crane to traverse. Limited travel will be allowed

only to travel the crane off the slope. Continued op

eration with an engine service monitor light on will

result in engine damage.

7. Avoid steering on a slope. Steering on a slope isnot recommended. Always travel straight up or

down the slope. Avoid traveling with a side to side

slope. Grade the path to eliminate any side to side

slope.

8. Maintain gradual approach and departure angles.

Grade the top and bottom ends of a slope to form agentle break-over angle. This will prevent the

crane from lunging when the center of gravity

crosses over the top of the slope.

Transporting The CraneWhen transporting the crane, precautions should be

taken in securing the crane to the trailer, barge, or other

means of conveyance. The lower cross axles are the

recommended tie down points.

CAUTIONIf chains are wrapped around the cross axles,be certain the chains will not damage any lines

or components.

Always exercise safety and follow all local codes when

loading, unloading, or transporting the crane.

Prepare crane as follows before transporting it:

1. Properly disassemble the attachment. Refer toSection 4 of this Operator's Manual for the correctprocedures.

2. Remove the counterweights and retract the sideframes. Refer to “Counterweight Removal AndInstallation” and “Extending And Retracting TheSide Frames” in this Section of this Operator'sManual.

3. The upper must be positioned directly over theside of the lower with the travel swing lock engaged.

Note: The base section may be left on the craneduring transport, only if load limitations permit.

4. The live mast must be over the front of the upper.5. All control levers in operator's cab must be in neu

tral and the gate lock lever in the “STOP” position.6. Remove the keys from the crane and lock all win

dows and doors.7. Depending on the specific situations, further

preparations may be needed to protect the cranefrom the environment or vandalism. See “CraneStorage” for further suggestions.

Operator's Manual


Transporting The Tubular

BoomWhen transporting the tubular boom sections, precau

tions should be taken in securing the sections to the

trailer. The following is the suggested method of tubu

lar boom tiedown for transport. When transporting tubular boom sections, the following conditions must be

met:

CAUTIONIf tubular boom sections are improperlysecured to the trailer, damage could occur

which may weaken the structural integrity of

the boom.

1. Spread-axle trailers are recommended for trans

porting boom sections. Locate rear blocking be

tween, or forward of, the rear axles. Refer to

Figure 1-85, Detail 1.

2. On close-group axle trailers, rear blocking mustbe located forward of the rear axle group. Refer to

Figure 1-85, Detail 2.

3. Do not tie down in mid span.4. Do not strap over top of boom.

5. Secure boom to the trailer with 4” (10cm) nylon

straps over bottom boom chords as shown.

6. Wood blocking should be located directly under

nylon straps in two (2) places.

7. Nylon straps must be kept very tight. Check strap

tightness often. Straps must be twisted to preventvibration.

8. Boom Length = 10', 20', or 30' (3.05m, 6.1m, or

9.1m) boom extensions.

9. Boom extensions stacked together on a trailer

should be of equal length. If extensions cannot be

of equal length, refer to Figure 1-85, Detail 3 foradditional tie down instructions.

10. Counterweights are allowed under boom sections.

Transport boom sections on trailers with other

crane components whenever possible. Do not tie

boom directly to these other loads. Do not stack

loads on top of boom sections.11. Pendants should be secured to top of boom sec

tion during transport. Locate pendants along the

centerline of the boom and secure each pendant to

the top lattice in a minimum of four (4) locations.

Crane StorageAny time the crane is going to be left unattended, it

should be prepared so that it will not be damaged by

the elements, be an attraction to vandals, or a plaything

for children.

Short Term Storage1. Do not leave the crane where it will be a traffic haz

ard.

2. Lower all loads to the ground.

3. The attachment can be left in the air provided that

the “Wind Restrictions Guide” in the Crane Rating

Manual is adhered to. If the wind velocity exceeds

these guidelines at any time during crane storage,position the attachment on the ground. Do not

take chances. If possible, store the attachment on

the ground. Refer to the Crane Rating Manual for

wind speed and other applicable restrictions.

4. If the attachment is left in the air, tie off the hook

block and/or hook ball and keep the winch wirerope(s) snug.

5. Ensure both drum brake pedals are latched in the

fully applied position and the boom hoist drum

pawl is engaged.

6. The travel swing lock must be engaged.

7. All control levers must be in the neutral position

with the lever lock switch in the “LOCKED” position.

8. Shutdown the engine and block the tracks to pre

vent the crane from rolling.

9. In cold weather, locate the crane where it will not

freeze to the ground.

10. Remove the keys from the crane and lock all windows and doors.

Long Term Storage1. Store the crane inside a building if possible.2. Lower all loads to the ground.3. The attachment can be left in the air provided that

the “Wind Restrictions Guide” in the Crane Rating

Manual is adhered to. If the wind velocity exceeds

these guidelines at any time during crane storage,

position the attachment on the ground. Do nottake chances. If possible, store the attachment on

the ground or remove it from the crane. Refer to the

Crane Rating Manual for wind speed and other ap

plicable restrictions.

4. If the attachment is left in the air, tie off the hook

block and/or hook ball and keep the winch wirerope(s) snug.

5. Thoroughly clean the crane.6. Touch up any spots where paint has chipped. This

will prevent rusting.7. Lubricate the entire crane as per the lubrication

chart. Make sure all gear cases are filled to theirproper oil level.

8. If possible, block the crane up so the tracks clearthe ground. Make sure the blocking is placed sothe crane cannot fall off it. If this is not possible, setthe crane on planks so the track will not sink in theground. Block the track to prevent the crane fromrolling.

9. Fully retract all hydraulic cylinders. Cover all cylinder rods, machined, and unpainted surfaces with acoat of grease.

10. All control levers must be in the neutral positionwith the lever lock switch in the “LOCKED” position.

11. Shutdown the engine and allow it to cool. Cover allopen areas around the engine, cab, etc. to prevententry of water. Cover the entire engine area with atarp if possible.

12. Prepare the engine as per the engine manufacturer's manual. Make sure antifreeze protection issufficient to prevent the engine from freezing. If antifreeze protection is not adequate, completelydrain the engine block.

13. If in a location where vandalism may occur, lock thecab doors. Cover all cab glass with plywood orboards to prevent glass breakage. Provide ameans of locking the engine access doors, fueltank, and hydraulic reservoir.

14. Store the crane so it does not provide a playthingfor children. Such a unit can be an “attractive nuisance” for children to play on. If they fall off it or getentangled, serious injury may result.

15. While in storage, the crane should be “exercised”every 60 days to ensure the working condition ofthe crane. Start the engine and operate allswitches, control cables, and hydraulic functionsseveral times to circulate lubricants and to keep allmechanisms and linkages operative.
