4.0 OPERATING PROCEDURE

IT IS IMPERATIVE THAT ALL PERSONS USING, OPERATING OR MAINTAINING THIS DRUM TRAILER BE FULLY TRAINED AND COMPETENT TO DO SO, AND HAVE READ THE ENTIRE OPERATING MANUAL.

CBS PRODUCTS LTD CANNOT BE HELD RESPONSIBLE FOR MIS-USE OF THIS EQUIPMENT.

4.1 Attaching to Vehicle – The CBS 751 Cable Drum Trailer is designed for towing behind a category M1, M2 or N1 vehicle, therefore ensure that the towing vehicle has the correct towing arrangement to match the trailer. It should also be at a height which enables the trailer to travel in a horizontal position, and not leaning up or down, (Ensure that there is a positive nose weight). If the latter is the case, the vehicle towing arrangement should be adjusted to suit.

The towing facility on the trailer is to E.U. specification and is of the inertia type (i.e. overrun). The towing bracket is fitted with a handbrake for holding the trailer in the stationary condition. It is essential to apply the handbrake when the trailer is separated from the towing vehicle.

The adjustable height jockey wheel allows the towing eye to be adjusted to ease the operation of attaching the trailer to the vehicle. Once attached the safety wire should be applied around the towing pin of the vehicle.

The 13 pin lighting plug is wired to current E.U. regulations . The plug should be connected to the vehicle socket before towing commences. If a light frame is fitted ensure the plug is correctly fitted to the trailer mounted socket. To avoid problems with the electrics it is advisable to ensure the plug is kept dry and free from dirt. When fitting and removing the plug do not pull on the connecting cables.

Ensure that the retaining clip on both rear prop stands is fitted and the handle is positioned inline with the main chassis side member when in the raised position.

Page 16: CBS 751 - CBS Products

16

4.2 Loading the Trailer – It is safer to load and unload the

trailer when it is attached to the vehicle, and to adhere to the following:

Ensure handbrake is applied.

Lower rear prop stands to ground and lock in position.

If the trailer is fitted with a removable light frame, this must be removed prior to lowering or installing a drum, (the lighting frame will be damaged by the drum if this is not done), This is accomplished by first removing the securing padlock and R clip, un-plugging the electric’s, and then lifting the anti-luce connectors. The complete lighting board can then be removed and stored safely, until required for re-assembly, always ensure that the securing padlock and R clip at fitted on re-assembly, always check the light functions after removing the lighting frame.

Remove the travel pins at the top of the frame.

If a braked drum spindle is fitted remove the brake retaining pin.

Open the ram valve to each ram, positioned next to the hand pump.

Release the small tommy bar control knob on the hand pump body.

Apply a light load on the drum spindle to assist with lowering.

Remove the vertical spindle retaining pins – one each side, temporally store in the tubes on the drum frame brace until required again.

Lift out the spindle from the lifting pockets.

It should be noted that the conductor or cable should be fed from the rear of the trailer and off the top of the drum. The trailer should also be attached to the vehicle.

Unscrew the location spindle collar and remove from the spindle.

Ensure that the drum shaft and collars are free from dirt and debris, apply a smear of grease to the revolving collar bores

Slide the spindle through the drum to be loaded, ensuring the collar is located inside the drum.

When fitting the brake drum assembly ensure the torque arms are located securely behind the nuts of the drum. SECURE to the drum using coach bolts.

Page 17: CBS 751 - CBS Products

17

Refit the spindle locating collar, ensuring the inner part of the collar fits securely into the drum and then lock. IMPORTANT – The drum must be located firmly on the collars and there should be no end play on the drum.

Roll the drum into the trailer chassis.

Present spindle to spindle pockets and insert the spindle retaining pins one each side and secure with the ‘R’ clip attached. If necessary raise spindle pockets to locate spindle by closing the valve with the tommy bar lever on the hand pump and operate. If the drum is on uneven ground then close the valve to the highest ram by adjusting the lever on the single ram valve and pump. Once level, engage the spindle in the pockets, ensuring they are in the same pocket each side, refit the vertical spindle retaining pins – one each side.

Continue pumping as required to lift to the elevated position. Do not over lift. The drum should be kept level at all times.

When the spindle assembly has been raised to its full height insert the travel pins and lock in position by inserting the retaining ‘R ‘ clips. Important - Check the condition and function of the retaining ‘R’ clips each time used, (replace if worn, distorted or faulty).

Important: - when travel pins are fitted and secure always release the valve on the pump by unscrewing it. This will ensure that the drum weight is being carried by the travel pins and not by the rams, this will considerably increase the life of the rams.

If a braked drum shaft is fitted fit the brake retaining pin and R clip.

Lift the rear prop stands and you are ready to tow your trailer, ensure that the retaining clip on both rear prop stands is fitted and the handle is positioned inline with the main chassis side member when in the raised position.

4.3 Positioning and Braking of Conductor Drum – Once on site, position the trailer at approximately 20-30 metres distance from the first pole to be strung. Align the trailer so

Page 18: CBS 751 - CBS Products

18

the centre of the drum is in line with the first pole. This ensures the conductor comes off the drum without fouling the drum flanges.

Ensure the drum is loaded with the conductor feeding off the top of the drum. Anchor the trailer down, by either leaving attached to towing vehicle or by the use of slings and ground anchors (CBS 804), and also apply the trailer brakes. Lower the rear prop stands of the trailer to stabilise during the pulling operation, on soft ground it may be necessary to place wooden battens under the rear prop stands to spread the load, the trailer must be stable and adequately restrained. Check that the drum retaining pins and brake pins are located correctly and have not moved during transportation. Do not use a drum which does not fit the drum collars. If drums with larger diameter spindle holes are to be used, it is recommended that you order special collars from CBS Products (KT), LTD. to suit in advance of operating the drum trailer. For a drum braking operation apply the drum brake lightly by turning the tommy bar on the screw handle. Rotate the drum slightly by hand to ensure that the brake band is just making contact with brake drum. Note: The tommy bar screw controls the braking at a coarse level, and should be left set once the required tension is achieved. The brake lever provides finer control of the tension and can be adjusted by the operator during the stringing operation if necessary.

4.4 Lowering the Conductor Drum If a detachable

light frame is fitted it must be removed before lowering

or installing a drum. Remove the brake pin close the valve on the hand pump by screwing in the tommy bar. Raise both rams sufficiently to support the weight of the drum. Remove the travel pins, followed by opening both ram control valve on the hydraulic circuit. Now unscrew the tommy bar on the hydraulic hand pump, this will release the pressure and lower the drum. Try to

Page 19: CBS 751 - CBS Products

19

keep the drum spindle parallel as the drum is lowered. Do not allow the drum to drop quickly. Once the drum is on the ground, remove the vertical retaining pins and roll the drum out of the trailer. Remove the collar, slide the spindle out and re-assemble on the trailer. For transit ensure that the retaining clip on both rear prop stands is fitted and the handle is positioned inline with the main chassis side member when in the raised position.

5.0 MAINTENANCE AND SERVICING

5.1 Hydraulic Circuit – The hydraulic circuit is a simple arrangement consisting of the following:

Hydraulic hand pump including open and close valve. C-751-650 kg C-751-1000 kg C-751-1300 kg

One – Ram control valve

Two – Hydraulic lifting rams

In the case of oil loss, the hydraulic tank should be topped up with hydraulic oil – Tellus 32 – or equivalent. Joints should be checked for leaks and tightened if necessary.

5.2 Brakes and Tyres – The brakes fitted are the auto reverse type to make towing easier. The maintenance of the drum brakes should be undertaken by trained personnel only, and adjusted when necessary to ensure the drums just run clear when the wheel is rotated in a forward direction only. It is important to keep these adjusted every 6 months, as too large a drum movement can affect the performance of the auto reverse facility and parking brake.

After adjusting the drum brakes, remove any slack in the operating system by loosening the lock nut and tightening the pull rod, but without pre loading brakes (check this again by rotating each wheel in a forward direction). The tyres should be checked weekly, refer to Section 3 for details. The linkage mechanism should be oiled weekly to ensure smooth operation and to protect from moisture. Check the condition of the brake cables weekly, replace if frayed or damaged. Apply a light oil as required to ensure cables move freely.

Page 21: CBS 751 - CBS Products

21

SERVICING a) Apply grease to ball and to cup of ball head after cleaning each item.

(Alternatively towing eye and jaw if fitted). This to be carried out each time the trailer is to be towed.

b) Oil all moving parts weekly having wiped away all corrosion and dirt

deposits. c) Every 3,000 miles or 3 months, or as necessary, apply grease gun to

grease nipples fitted to the coupling using general purpose grease. d) After first 500 miles, then every 3,000 miles (or more often if required),

adjust wheel brakes at back plate adjusting points, to take up any wear. Follow brake manufacturers appropriate instructions in this respect.

NOTE: do not adjust for brakewear anywhere other than at the wheel brakes themselves. An indication of break wear will be given by increased handbrake travel. e) After adjusting the drum brakes, remove any slack in the operating system

by loosening the lock nut and tightening the pull rod (see sketch), but without pre-loading brakes (check this again by rotating each wheel in a forward direction).

f) Check ball head for wear each time trailer is used, (if applicable). g) Check the condition of the brake cables every week, replace if frayed or

damaged. h) Check the condition of the brake away cable each time the drum trailer is

used, replace if kinked or damaged. i) Check the condition of the pin retaining wires each time the drum trailer is

used, replace if kinked or damaged. j) Check the condition and function of all retaining ‘R’ clips each time the

drum trailer is used, (replace if worn, distorted or faulty). k) Check the wear on the drum spindle brake, if the brake lining is worn to

within 2 mm of the rivets the brake band should be replaced.

l) Check the condition of the lighting cables and light operation, rectify if necessary.

6.0 TOWING INSTRUCTIONS

BEFORE TOWING a) Check the ball head cup is well greased (if fitted). b) Handbrake is fully applied. c) Raise the coupling head above height of ball bracket by use of jockey

wheel provided. d) Reverse towing vehicle until ball bracket is directly below ball head on

coupling. e) Grasp locking handle on top of coupling and press trigger backwards with

thumb. Then lift handle (you can now release trigger). With handle still raised wind up jockey wheel until ball on towing vehicle enters ball cup on coupling. Now release handle and continue winding up jockey wheel until locking handle automatically drops down and trigger snaps shut. If this does not occur lift handle again and check if ball seats this time and trigger snaps shut. If there is still no success, check if ball or head is worn.

f) If ball seats properly, then continue winding up jockey wheel until it is fully

retracted. g) If towing eye is fitted instead of ball head, remove pin from towing jaw and

reverse towing vehicle until eye enters jaw. Then replace pin and locking pigtail or other securing device.

h) Continue to wind up jockey wheel until fully retracted and wheel is no

longer free to rotate. Loosen jockey clamp and raise jockey wheel up into chassis with wheel facing rearwards and re-tighten clamp firmly ensuring wheel is well clear of brake linkage, ensure that the rear prop stands are raised and secured and that the retaining clip on both rear prop stands are fitted and the handles are positioned inline with the main chassis side member.

If an additional front mounted prop is fitted, ensure it is correctly stowed and secured for towing.

Please remember brake linkage and handbrake must be free to move fully during overrun braking when on the road so that breakaway cable can apply brakes if trailer should part company with towing vehicle.

Page 23: CBS 751 - CBS Products

23

i) Check condition of breakaway cable. If frayed or kinked at all replace immediately before use. Then connect breakaway cable to towing attachment on towing vehicle. The cable must be free of knots.

j) Connect electrical plug to socket on rear of towing vehicle, lighting frame

to trailer mounted socket. (if applicable) and check all lights are fully operational.

k) Check the load is distributed to give the correct nose weight for the

coupling, refer to Section 3 for information on the hydratow coupling, a positive nose weight is required to ensure stable towing. Also ensure nose weight is within limit of towing vehicle.

l) When fitting the number plate ensure that if is fitted centrally beneath the

number plate lamp if illuminated from above and centrally between the two lamps if illuminated from each side..

m) Ensure that the retaining clip on both rear prop stands is fitted and the

handle is positioned inline with the main chassis side member when in the raised position.

n) If towing with a car transporter vehicle, or any other vehicle, which has a

long rear overhang, extra forces can be applied to the coupling and towing device causing rapid wear and damage. Please consult our Sales Department.

WHEN ON THE ROAD REVERSING – AUTO REVERSING BRAKES a) Simply reverse with towing vehicle having checked all is clear around you.

Initial resistance will be felt as brakes are applied on trailer and then automatically ‘roll-off’, allowing reversing to continue. If reversing a heavy trailer up an incline, or on grass or other slippery surfaces, wheel spin on the towing vehicle may occur, as brakes initially come on.

b) If so, simply pull forward on to flat surface and recommence reversing

operation from there. c) If trailer regularly has to be reversed up a steep incline, then an optional

manual override for such conditions can be offered.

a) Apply handbrake fully (if energy stores is fitted to rear of coupling then apply further pressure to the handbrake to compress the spring which is fitted within the energy store component). This ensures that should brake roll-off occur when a trailer is parked with the rear facing down an incline that the brakes will automatically be re-applied. . Please remember brake linkage must be free to move fully during overrun braking when on the road, also handbrake so that breakaway cable can apply brakes if trailer should part company with towing vehicle. If the unit is fitted with a power assisted handbrake, then no further action is required as the handbrake will automatically take up any further movement should roll-off start to occur when parked on a slope.

b) Disconnect electrical plug from socket and store in safe position. c) Loosen jockey clamp and lower jockey wheel to ground. Firmly re-righten

clamp (by hand). Press back trigger with thumb and lift handle on coupling head. At the same time raise front of trailer by use of jockey wheel until head is fully clear of ball on towing vehicle, if additional front mounted prop is fitted, ensure it is correctly lowered and secured.

d) Disconnect breakaway cable from towing vehicle. e) Drive towing vehicle clear of trailer. (in the case of a coupling fitted with an

eye follow above instructions except in respect of the final disconnecting of the towing vehicle in which case the instructions supplied with the towing jaw or hook should be used accordingly).

f) As extra security it is strongly recommended that the wheels of the trailer

should be chocked as an additional safeguard.
