Towing the truck crane
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 vehi-
cle, including tow-rod.
– If the engine, steering and service brake still work, you can tow the truck
crane with a lorry.
– 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.
