Extension/retraction of the telescopic boom
The movement is actuated by a hydraulic cylinder.
Lifting/lowering of the jib
A hydraulic cylinder located between the frame and the jib arms facilitates this operation.

Cage levelling can be corrected manually, as it may become unbalanced during repeated boom lifting
and lowering manoeuvres.
