COMMON COMPONENTS SLIPCHAIN SYSTEM


EQUIPMENT SPECIFICATION Section 1

General Description of System 1. Slipchain Track

The track is made from Aluminium alloy extrusions with a low friction slide for the chain. The sections consist of a main channel and a bridge section which encloses the air tube, and a steel channel which supports the slide. The space below the bridge forms a return tunnel for the chain which runs along the top of the track on the slide and returns around the idler sprockets at each end of the track, returning to the drive unit mounted below the track. The complete track system is made up of standard sections, air inlet sections and end sections, the combinations of which are manufactured to suit customers’ requirements. Each section is nominally 2m long and has nine steel guide pins evenly distributing the upwards thrust of the air tube, through the bridge section of the main channel. The chain is contained within a channel shaped UHMW profile, with side guide flanges. This eliminates the possibility of the chain wearing the steel support channel, especially where side movement of the chain occurs through pallet drift (or fork lift truck operations on flat bed trailers).

2. Drive Unit

This is a robust steel welded fabrication containing drive and idler sprockets running on shafts mounted in grease lubricated plummer block bearings. The unit is fitted with integral chain tensioners with a self-adjusting slack take up facility preventing the chain ‘jumping’ the drive sprocket as chain stretch takes place. Initial chain tension requirement is reduced and can be accurately applied by compressing the tensioner springs to a predetermined length.

3. Power Unit

The power unit is typically a 4KW a.c. motorised gear unit with twin output shafts centrally positioned to drive two Slipchain track drive units via chain couplings. Output speed is nominally 31 rpm giving a linear speed to the chain, depending on drive sprocket size, within the range 6 - 10m/min. Where required, separate hydraulic drive motors may be specified for each track. The motorised gear unit is pre-filled with a synthetic oil lubricant to provide improved starting characteristics in cold weather temperatures down to -25°C, yet providing good lubrication qualities at up to +80°C.

EQUIPMENT SPECIFICATION Section 1 4. Track End Idlers

A robust but compact idler sprocket assembly is fitted at both ends of the Slipchain track. These have 16 teeth for normal applications, but may have 14 teeth where the chain is required to be lower when retracted to minimise the chance of damage when pallets are loaded onto the vehicle from the side.

5. Lubrication The Slipchain track system requires lubrication at a total of 20 positions. Although accessible, these points can be connected to an automatic lubrication unit arranged to pump accurate amounts of grease to each point during operation of the Slipchain system, or a centralised system which reduces the number of greasing points to 6.

6. Control Raising and lowering of the Slipchain track is effected by pneumatic controls. These can be either manually operated or automatically/ remotely operated with an optional manual override. Air is supplied from the vehicle’s own system, which is protected against depressurisation by an automatic valve to an air reservoir. From here it is supplied via pressure regulators to the control valves. A variety of options for emergency charging, stand by supply and air shut-off is available. Power for the Slipchain drive is supplied from the dock or warehouse via a plug and socket. Control of the drive may be either manual via a pendant or control box, or automatic, including PLC control, and may be dock or vehicle mounted. All control systems are supplied to customer requirements.

ROUTINE MAINTENANCE Section 2

To be carried out by customer or maintenance contractor.

SLIPCHAIN General Notes • Ensure that systems are disconnected from electrical power supply before commencing any

repair or maintenance work. • Ensure air systems are isolated from supply and that system pressures are released before

disconnecting any air equipment. • Repace all covers and guards after inspection. 1st and 2nd weeks of Service

1. Check tension of chains daily and adjust as necessary - see Chain Tensioning Procedure. 2. Carry out weekly checks.

3rd and 4th weeks of Service, by customer or maintenance contractor

1. Check tension of chains and adjust as necessary - see Chain Tensioning Procedure. 2. Carry out weekly checks.

Weekly checks by customer

1. Ensure that vehicle/dock floor, associated roller tracks, Slipchain tracks and track end sprockets are free from dirt and debris. Blow out debris with air line as necessary. 2. Ensure that Slipchain drive units are free from debris. 3. Wipe clean electronic sensors if fitted, taking care not to damage sensor face. 4. Check that Slipchain system operates freely in both forward and reverse directions, and in both the raised and lowered mode. Investigate any extraneous noises from the system. 5. Drain water from air reservoir and from filter regulator filter bowls. 6. Check air regulator pressures are to original settings and adjust if necessary.


Monthly checks by customer or maintenance contractor

1. Check chains for damage/wear. Replace part section or completely as necessary. 2. Check UHMW slide blocks for wear and replace as necessary. 3. Check Slipchain drive unit sprockets and end of track sprockets for damage/wear. Replace as necessary. 4. Check for leaks at all air line connections and control equipment connections and repair as necessary. 5. Ensure pressure protection valve is operating correctly - see PPV Checking Procedure. 6. Check tension of Slipchains and adjust as necessary - see Chain Tensioning Procedure. 7. Lubricate Slipchains lightly with chain oil spray. Vegetable oil may be substituted for mineral oil where the latter is unacceptable. Clean away any surplus oil form chain. 8. Re-grease all Slipchain drive unit and track end bearings - see Lubrication Diagram. Alternatively, if an automatic lubrication system is fitted, top up reservoir with grease and check system is functioning correctly. Re-filling the grease reservoir is achieved through a standard grease nipple situated on the side of the pump, by means of a grease gun or filler pump. Clean away any surplus grease from components. 9. Check lubricant level in motorised gear unit and top up if necessary. Visually check for leaks at shaft seals. 10. Check hydraulic system for leaks, tightening connections where necessary or refitting. Carry out maintenance of hydraulic power pack and top up hydraulic reservoir - see Power Pack Installation and Maintenance Instructions. Check operation of power pack and operating pressures. 11. Ensure Slipchain system is disconnected from electrical power source and check that all electrical connections are free from corrosion and provide good contact. 12. Wipe clean electrical control panels and ensure switches/push buttons are operating correctly and indicator lamps are working. 13. Check status of batteries and recharge as necessary. 14. Carry out weekly checks.


Half-Yearly Checks by customer or maintenance contractor

1. Release chain tension and split chain.

Note: Care must be taken when adjusting nuts are removed as springs may still be in compression. Lift out Slipchain inner channels and clean system thoroughly.

2. Carry out maintenance to motorised gear unit - see Operations and Maintenance

Instructions. 3. Check the air bag for damage and leaks. 4. Re-assemble Slipchain and tension chain. 5. Remove drive coupling guards, check coupling components, lubricate and replace guards. 6. Check security of all system components. 7. Carry out monthly checks.


Chain Tensioning Procedure Introduction Chain tensioning is necessary to prevent slippage between the chain and the drive sprocket during operation. The tension in the chain is indicated by the length to which the springs beneath the Slipchain drive units are compressed. Retensioning is necessary because the chain stretches. This stretch is relatively large during a chain’s early life whilst the minute surface irregularities of the chain components wear and ‘bed in’. Initial Tensioning 1. Assemble the tensioners in the drive unit with the compression springs and setting tubes in

position, and the M24 adjusting nuts just on the ends of the tensioner rods by 2 or 3 threads. 2. Thread the chain through the drive unit and bring ends together but do not join at this stage. 3. Using a spring compressor or jacking equipment, compress the spring until it and its setting tube

is clamped tightly to the underside of the drive unit. 4. Pull together the ends of the chain and join with a connector link, making the chain as tight as

possible. Several links may have to be removed from the chain to accomplish a degree of chain tightness. This action will have the effect of pulling the tensioner units until the M24 adjusting nuts are against the underside of the compressed springs.

5. Release the compression springs, then tighten the M24 locknut compressing the springs until

there is a 1mm gap between the setting tube and the thrust bearing face. Check this using a 1mm feeler gauge.

6. The correct tension in the chain should now have been achieved, and the distance between the

underside of the tensioner cradle and the top surface of the drive unit bottom-mounting plate should measure approximately 100mm.

If the distance is less than 100mm, then it will be necessary to release the tension in the chain, split

the chain and remove more links. The chain can then be retensioned as before. 7. Refit all components and tighten the M24 locknuts against the adjusting nuts before starting the

Slipchain.


Retensioning Retensioning of the chain should be carried out when, with the Slipchain stationary, the springs have extended by 20mm. To retension the chain, loosen the M24 locknuts on the tensioner rods beneath the Slipchain drive units, and turn the M24 adjusting nuts compressing the springs, back to the original setting of a 1mm gap between the setting tube and the thrust bearing face. Retighten the locknuts against the adjusting nuts before restarting the Slipchain. Should retensioning be required more than twice in succession, then it will be necessary to remove one or two links from the chain. To achieve this, loosen and remove the locknuts, loosen the adjusting nuts to the ends of the tensioner rods, and repeat the procedure for initial tensioning. Note: Care must be taken when loosening the adjusting nuts as the springs may still be partially compressed. Refit all components and retighten the locknuts against the adjusting nuts before restarting the Slipchain.


Motorised Gear Unit Oil Level Checking Procedure Introduction The motorised gear unit used to drive the Slipchain system requires an oil quantity of 9.1 litres. When cold, the level of this oil quantity does not reach the level plug, and an oil level check using the level plug is not possible. During running, the oil in the gear unit warms and is aerated, and thus increases in volume to such an extent that the apparent oil level reaches the plug. Checking Procedure 1. Run the system to warm and aerate the oil. 2. Remove the oil level plug and check that the oil level is at or slightly below the plug aperture. 3. Top up as necessary with clean oil and refit the filler plug. 4. Re-run the system and re-check the level allowing excess oil to drain from the level point into a

suitable receptacle. 5. Refit the oil level plug. Note: See also “Geared Motors and Gearboxes” Operating and Maintenance Instructions.
