2-1. Safety Notesa. Inspect the hoist for any evidence of shippingdamage or loose parts.b. The supporting structure and load attaching devicesshould have a load rating at least equal to that of thehoist.c. This hoist is not suitable for use in uncoveredoutdoor locations or areas containing explosive dust,vapors or gases.d. The installation area must provide safe operatingconditions for the operator, including sufficient roomfor the operator and other personnel to stand clear ofthe load at all times.e. In areas where slack chain hanging from the hoistmay create a hazard, use a chain container (see Figure2-2).2-2. Hanging the HoistHook mounted hoists can be used with a variety oftrolleys or stationary hangers. It is recommended that ahand-geared or motorized trolley be used when thepulling effort required to move the hoist exceeds 100pounds or when the application requires frequentmovement of the hoist.a. Make sure that the hook latch closes after hangingthe hoist.b. The standard top hook is restrained from rotation bya plate and two screws. The hook can be made toswivel freely by removing the plate, or can be rotated90° and fixed in that position.c. SeeFigure2-l for instructions on adjusting lug-mounted plain trolleys.d. Refer to Coffing Motorized Trolley Operating andMaintenance Instructions manual for motorized trolleyinstallation instructions.2-3. Power Supply Connectiona. Disconnect power before making connections.b. Voltage supplied to the hoist should be within plus orminus 10% of the voltage specified for the hoist.Hoists are tagged at the factory with a tag indicatingthe voltage for which the hoist is wired. Standardsingle phase hoists are convertible from 115 to 230volts. Standard single speed, three phase hoists areconvertible from 460 volts to 230 volts. See the Wiringsection (paragraph 7-1) for voltage conversioninstructions.c. National Electrical Code (ANSI C1) and localelectrical codes should be consulted and properdisconnects, branch circuit protectors, and wiringprovided.d. Power cables furnished with the hoist have a greencolored ground wire which must be securely connected

to the electrical system ground.

e. When installing athree-phase hoist, make only temporary connections at the power line. Push the"UP" button and observe the direction of the hook. If itraises, the phasing is correct and permanentconnections may be made at the power line. If the loadblock lowers when the "UP" button is pushed, releasethe button immediately since the limit switches will notoperate to protect the hoist from over-travel. Reversethe red and black wires at the power line connection tocorrect the hook direction.

CAUTIONDo not change connections in the hoist or thepushbutton assembly.2-4. Vent PlugA pressure relief plug (Item 24, Figure 8-2) is providedwhich will vent excess pressure from the transmissionhousing.2-5. Chain LubricationThe hoist chain should be liberally oiled before placingthe hoist into operation. For lubrication instructions,see paragraph 5-6.a.2-6. Testinga. Before placing the hoist into operation, check forproper limit switch operation. Push the "UP" buttonand verify that the hook block stops at least 2 inchesfrom the bottom of the hoist. Run the hoist down to itslower limit. At least 12 links of chain should remain onthe slack end. If either switch is not correct, adjustaccording to the procedure outlined in paragraph 5-2.

NOTEThe upper and lower limit switches are factory set toprovide the maximum allowable hook travel. Thistravel adjustment should not be increased. However,the switches may be adjusted to stop the hook sooner ateither end of its travel.b. Attach a light load to the hook and check the hoistfor proper operation. The load should stop withoutnoticeable drift when the pushbutton is released.Increase the load to near rated load. The hoist shouldstill lift the load without hesitation and stop with nomore than one inch drift.2-7. Trolley InstallationFor Lug Mount and Plain Trolley configurations referto included manual part number CTA698-1.

d. Bring the hook into engagement with the load and makesure it is well seated before proceeding to lift the load.On multiple reeved hoists, be sure that the load isequalized on all supporting chains.

e. Lift the load just clear of its supports and stop the hoistto check for proper brake operation.

f. Avoid letting the hook or load swing excessively whilemoving a trolley suspended hoist.

3-4. Overload Limiting ProtectionThis hoist is equipped with a factory-calibrated overloadlimiting clutch, which permits lifting loads within rated

capacity and prevents lifting excessive loads which coulddamage the hoist. If the load exceeds the lifting capabilityof the overload clutch, the hoist will not lift the load, but themotor will to run as long as the "UP" button is pressed.Repeated attempts to lift an excessive load will overheat theoverload clutch and cause permanent damage to the clutch.

CAUTIONThe overload limiting clutch is an emergency protectiondevice. It should not routinely be used to measure themaximum load to be lifted.

4-1. GeneralA scheduled inspection routine should be established forthis hoist based upon severity of use and environmentalconditions. Some inspections should be made frequently(daily to monthly) and others periodically (monthly toyearly). It is suggested that an Inspection and MaintenanceCheck List and an Inspector's Report similar to thoseshown in Figures 4-1 and 4-2 be used and filed for reference.All inspections should be made by a designated inspector.Special inspections should be made after any significantrepairs or any situation causing suspicion that the hoist mayhave been damaged. Any hoist which has been removedfrom service for an extended time should receive aninspection as described under Periodic Inspections. ANSIB30.16, Safety Standard for Overhead Hoists, providesguidelines for hoist operation and inspection.

CAUTIONAny unsafe condition disclosed by any inspection mustbe corrected before operation of the hoist is resumed.

4-2. Frequent Inspection

a. Check pushbutton station, brake and limit switches forproper operation.

b. Check hooks for deformation, chemical damage orcracks. Bent hooks or hooks damaged from chemicals,deformation, cracks or having excessive throat opening(see paragraph 4-6) should be replaced. Visibledeformation of any hook may be evidence of hoist abuseand overloading and indicates that a thorough inspection ofthe complete hoist should be made.

c. Check that bottom hook swivels freely.

d. Check for missing, bent or otherwise damaged hooklatches.

e. Check pushbutton and power cord for cuts or otherdamage.

4-3. Periodic InspectionThe exact period for the following inspections will dependon the anticipated severity of hoist use. Determination ofthis period should be based on the user's experience. It isrecommended that the user begin with a monthly inspectionand extend the periods to quarterly, semiannually, orannually, based on his monthly inspection experience.

a. Clean hoist of any dirt or foreign material. Inspectbottom block for accumulation of debris.

b. Perform all frequent inspections listed above, c.

Check for loose bolts, screws and nuts.

d. Check housings, load block, and other parts for wear,corrosion, cracks or distortion. Check for abnormalopenings between housing sections.

e. Check motor brake for worn discs, oil contamination orexcessive clearance (see paragraph 5-3).

f. Check mechanical load brake function (see Figure 4-3).

g. Inspect the entire length of chain for gouges, nicks, weldspatter, corrosion, distortion and wear. See CHAININSPECTION, paragraph 4-5.

h. Inspecthooks and suspension parts for cracks, distortionor extreme wear.

i. Inspect hooks for cracks using magnetic particle, dyepenetrant or other crack detecting methods.

j. Check limit switch set points and reset if necessary (seeparagraph 5-2).

k. Inspect all wiring for defective insulation, and check tobe sure all electrical connections are tight. Check motorreversing contactor or relay for burned contacts.

1. Inspect for oil leaks. Check oil level.

m. Inspect for missing or illegible capacity or warninglabels.

n. Inspect the supporting structure for continued ability tosupport the hoist rated load.
