Do not pressure wash brake valves or electrical components
1. Park on level ground with enough clearance behind the trailer to drive or winch the load onto the trailer. Check the trucks air gauges to ensure the trailer is fully charged with air. Apply the park brakes, turn the PTO on and ensure the truck lights are turned on (The remote control is powered by the trucks lighting circuit and needs air to actuate the valves)
2. Go to the rear of the trailer to observe that the trailer is on level ground. Release the ramp chains while you are there
3. Remove the wood blocks from the rear of the ramp and place them under the back bumper, then lower the trailer onto the blocks using the ‘Suspension Valve’ at the rear of the top deck. When the trailer is on the blocks move the suspension valve to the HOLD position.
4. Can the load fit between the suspension pods.
Yes - it is wide enough to load Go to #7 NO - it needs to be widened Go to #5
5. Go to the rear of the trailer and use the remote controll to widen the trailer out fully. (When the trailer is widening try to keep the suspension pods parallal to each other)
6. When both sides are fully widened, lower the ‘in-fill decks’
7. Lower the ramp using the ramp control valve under the left rear of the top deck. When the ramp is fully lowered, PUSH the ramp valve handle over the detent to put the pamp into ‘float mode’ Check that the ramp tip is sitting flat on the ground. If it is not supported across its width the trailer needs to be moved to flatter ground.
8. Assess the load. - Will it drive on to the trailer safely using its own power?
YES I can drive the load onto the trailer
Go to #9
NO The load will need to be winched onto the trailer Go to #10 - Winch use
9. Drive the Load on to the trailer and tie down the load to the trailer.
10. WINCH operation
If the load is disabled or cannot be safely driven onto the trailer (insufficient or non-operational brakes…) the winch can be used to pull the load onto the trailer.
1. Activate the ‘Free-spool’ valve to release the winch brake. (This allows the winch rope to be manually pulled out.) Pull out the rope and fix the end to the load at a safe and strong recovery point.
2. Turn the free-spool off and operate the ‘winch IN’ function on the remote to pull the load onto the trailer. When the load is in the correct position, tie the load to the trailer.
3. Release the pull on the winch by winching out briefly
NOTE: you can leave the winch attached, but the load MUST be held to the trailer by its tiedown chains / Strops and not restrained by the winch
Has the trailer been widened.
YES But the load is now forward and I can close the trailer
YES But I need the trailer to remain widened
NO - - - -
Go to #11
Go to #13
Go to #13
11. Raise the ramp and secure it using the restraint chains then raise the in-fill decks and bring the suspension pods back in to their travel position.
12. Lift the ‘In-fill decks then bring the suspension pods back into their closed position.
13. Rise the trailer by putting the suspension valve back in TRAVEL mode. When the trailer has lifted off the wood blocks, return the blocks to their travel positions in the ramp.
14. Return to the truck and turn OFF the PTO
15. Release the brakes then move off slowly. The air suspension may still be raising to its final travel position.
On each occasion prior to using the transporter the following procedures must be carried out, to ensure the safe operation of the transporter and the safety of the personnel involved:
• Ensure that the maintenance schedule is up to date
• Walk around the trailer to check for obvious faults such as:
- Tyres are all correctly inflated including the spares
- Wheel nuts and studs are tight with none missing
- No air leaks from hoses, tanks, valves or couplings
- No hydraulic leaks from rams, hoses or valves
- No structural cracks to chassis
- Wheel alignment is correct
• Check that the trailer kingpin is the correct size and is fully engaged with the 5th wheel and that all of the hydraulic, electric and air couplings are fitted correctly.
• Test that brakes and lights are fully operational.
• Ensure that load security devices, which will be required, are carried. This means dunnage and matting. These are to be stowed securely to prevent movement while travelling.
• Check that you have the required permits to cover the load intended.
• Check that the suspension is set to the correct height
• Check that the route has adequate ground clearance to that which the trailer has available. This is particularly important over railway lines and off road situations.
• Allow for road traction, which is significantly reduced, in wet or unsealed conditions.
• Be aware of weather conditions as these can affect the load. Rain and Fog can reduce traction, increase stopping times and reduce visibility. High winds may affect the stability of the load. Hot conditions can increase tyre pressures and build up heat in the hub bearings
The air suspension is equipped with a ride height valves mounted on both sides of the rear axle ‘cassettes’ A docking valve is fitted on the Right side of the gooseneck to allow raising and lowering of the trailer.
Lowered position
Ride Height
The air is exhausted from all the air bags and the trailer will sit down on the axle stops. This is mainly for loading of plant onto the trailer.
The predetermined travel height position for the trailer. The trailer should always be set in this position when travelling. This position ensures that the axles will always be fully compensating for the load.
Raised Position Trailer air bags are inflated to raise the deck height
CAUTION:
When raising or lowering the suspension, the trailer will move backwards and forwards respectively. Never perform this operation while the trailer is resting on the landing legs as this may collapse the legs.
• Ensure that the trailer is on a flat even surface and there is at least 8 metres of clear space behind the trailer for loading when using the ramp. The surface behind the transporter should not be lower than the transporter wheels or you may damage the ramp.
• Place the trailer brakes in the parked position.
• Ensure the PTO is engaged, and the truck motor is running
• Place dunnage blocks under rear chassis beavertail both sides. The two blocks are located in Holders mounted to the rear of each widening cassette.
• Loosen and remove ramp chain binder.
• Lower the trailer suspension down onto the axle stops using the suspension control switch located on Right side of the gooseneck. (Leave in this position until load is secured.)
• Go to the ramp control valve (Left side of trailer at the rear of the top deck) and operate the lever to lower the ramp.
• Ramp float mode - Push lever, past the Down position, and over the detent, to put ramp in float mode.
• Load the equipment onto transporter and secure.
• Go to ramp control valve and operate the ramp lever to raise the ramp.
• Replace the ramp restraints and secure.
• Raise the suspension to travel position.
• Turn the PTO off
• NOTE: Always lower suspension before deploying ramps, otherwise damage to the ramp Hydraulic moto could occur.
When lowering the trailer, ensure there is no rocks or other hard objects under the chassis. CAUTION: Avoid point loading Chassis rails
Prior to loading you must understand the characteristics of the machine that is to be transported. If loading this yourself, you must have the relevant license or required expertise.
• Evaluate the following prior to loading:
- Machine weight
- Centre of gravity
- Width required to safely accommodate the track width with reference to the road conditions, terrain and stability.
- Final load position to comply with axle weights.
- Traction when loading over the ramps/beavertail. A winch may be required to load safely.
• Ensure that the transporter is on flat even ground and that you have sufficient space behind the transporter to load in a straight line. The loading operation must be protected from other traffic.
• Apply the truck and trailer brakes.
• Lower the trailer suspension.
• Remove the ramp securing chains and lower the ramps ensuring that no personnel or equipment are in the way. Leave ramp control in detented down position when loading or damage to ramp rams will occur. The ramps must be in full contact with the ground and bear evenly on each side of the transporter. When loading. The ramp valve must remain in the Detented FLOAT position.
• Load the machine according to manufacturer’s instructions. Care is to be taken at the apex of the beavertail, as the machine may become unstable. It may be necessary to use a winch to assist the loading at this stage. Position the machine to give the permitted axle loading.
• Secure the load as required by the Restraint of Load Regulations.
• Raise the ramp to the vertical position ensuring that they are clear of the load. The valve must remain in the mid-position once the operation is complete.
• Secure the ramp securing chain. Do not over-tighten.
• Raise the suspension back to ride height
• Check that the tyres are adequately inflated for the load on the transporter.
This trailer has a 16,000lb winch between the chassis rails at the front of the lower deck. The winch can be controlled either manually or by remote control
