7.5.3 Towing away the truck crane
Important
information
Observe the following if the truck crane has to be towed away:
– The truck crane may only be towed away with a tow-rod. Attach the
tow-rod to the tow-rod coupling on the front bumper.
– Be sure to observe the statutory regulations of the country in which you
are working concerning the overall length of the towing and towed
vehicle, including tow-rod.
– If the engine, steering and service brake still work, you can tow the truck
crane with a lorry.
– The wheels of the 4th and 5th axle lines must be in the forward position.
If the wheels can no longer be steered into the forward position, notify
Manitowoc Crane Care prior to towing.
– If the engine, steering or service brake no longer function properly, the
truck crane must be towed with a special breakdown truck.
The front towing coupling is designed for a maximum tractive force of 10 t
(22,000 lbs). Tensile force may be applied only forwards or at an angle of 45°
to both sides of the longitudinal axis of the truck crane.
In the case of
engine/transmis-
sion damage
The following information only applies to towing the truck crane out of
the immediate hazard area in the event of damage to the engine or
transmission.
Compressed-air supply
If the engine fails, the truck crane must be supplied with compressed air by
the tractor-vehicle so that the brake system is still operable.
