12.8.11 Operating the axle raising system
The axle raising system has two functions.
– Lifting/lowering wheels
When the truck crane is supported on outriggers, you can raise the wheels
(e.g. levelling horizontally) or lower the wheels (e.g. for driving with a
rigged mobile crane).
– Aligning the truck crane
When driving with a rigged truck crane, you can level the free-standing
truck crane – with a locked suspension, without first supporting the truck
crane on outriggers.
