T RANSPORTATION
CAUTION
The TL50 is not designed to be forklifted, and does not have provision on the Chassis to allow this
method of lifting. Ui recommends the procedure below for handling the machine.
WARNING
!!
See specifications at rear of manual for the weight of the work platform and be certain that lifting
apparatus is of adequate capacity to lift the platform.
B Y C RANE
The TL50 may be lifted by an overhead hoist/crane in the following manner :
Four lifting straps capable of safely supporting the total weight of the TL50 (2000kg) and being 2.4m long
for the axle straps and 3.4m long for the tow hitch straps and required. The strap length is important to
ensure the correct lifting angle is achieved (see diagram below)
The four lifting straps should be positioned as shown, care should be taken to ensure that they do not inter-
fere with any other parts of the TL50 and that they are secure before lifting.
B Y R OAD
It is important that before commencing transport to ensure the vehicle used is capable of towing 2000kg.
The TL50 is a road approved vehicle and therefore may be transported behind a motor vehicle of suitable
towing capacity. It is recommended that the vehicle used should have a tow bar where the top of the ball is
at a height of between 1.42 ft (435 mm) and 1.64 ft (500 mm) above surface level. These dimensions are
important for the following reasons;
1. The bottom of the Platform may be in danger of hitting the surface while driving if the tow hitch is above
the upper limit.
2. The towing vehicle will support too much weight if the Towhitch is too low.

Transportation
TL50 Service & Parts Page 11
Care should always be taken while towing the TL50 on an uneven or sloped surface. It is recommended
that the set of procedures that follow should be incorporated into a normal working practice for towing the
TL50 Work Platform. The Procedures which should be followed when transporting the TL50 are
1.The Platform is to be fully lowered, retracted and slewed in the correct position.
2.The Platform is to be securely stowed by closing the boom lockdown.
3.The Jockey Wheel that is fitted to the Towhitch is to be extended until the Receiver is close to the height
of the vehicle’s tow bar.
4.The Hand Brake is pulled to engage the brakes (important if the machine is not on a level surface).
5.The Outriggers are to be fully retracted and secured in position.
6.The key is turned to the off position.
7.Move the vehicle as close as possible to the Receiver.
8.Lift the Towhitch on to the tow bar and make sure the Receiver is properly secured.
9.Release the Hand Brake and retract the Jockey Wheel.
It is important that the Jockey Wheel is retracted as fully as possible so that the wheel will not slew (turn)
while being transported. Failure to do so could result in damage to the Jockey Wheel.
10.The tailboard harness is connected to the vehicle’s braking system by means of a 7 Pin Plug.
11.Attach the Breakaway Safety Cable to the towing vehicle.
The TL50 may then be towed.
If the TL50 is to be transported by other means then it must be securely tied down to the transporting unit
at several points.
Recommended securing points are the four outrigger support members on the Chassis and the Tow Bar-
weldment. Further securing points should be used if the terrain on which the unit is travelling is rough or
uneven. Care should be taken when using tie downs that sensitive parts of the TL50 (i.e. hosing, cabling
etc.) are not affected.
ALWAYS ensure that the Hand Brake is fully applied, that all the booms are FULLY stowed and that the
Boom Lock Down Pin is in place.
