12.1 Driving path
The path to be driven must be level. Uneven surfaces cannot be compen-
sated with the level adjustment system.
The entire driving distance must be level. The rigging modes and axle loads
specified in this chapter only for driving distances which are free of inclines
in longitudinal and lateral direction.
The ground must be stable enough to bear the axle loads.
If the surface pressure of the tyres exceeds the permissible load on the
ground, the surface area of the tyres must be increased by packing stable
material (e.g. wooden planks).
G
Risk of accidents due to partially obstructed view of the truck crane!
When driving the truck crane, always stay in visual or radio contact with a
banksman who can observe the parts you are unable to see, e.g. the raised
main boom in the
0° to the rear position.
G
Risk of overturning by slewing the superstructure!
When driving the rigged truck crane, the slewing gear must be switched
off – slewing gear brake engaged.
G
Risk of accidents when driving with a lifted load!
Driving the truck crane with a load lifted is prohibited. Always set down the
load prior to driving the truck crane and secure the hook block so it cannot
swing.
