Abstract

Provided in the supporting arm (1) of the loading machine is a telescopic arm (2a) which is displaceably mounted in it and to the front end of which (at 3) a load-suspension means actuated by means of hydraulic cylinder is fastened. The hydraulic line (6) extending from the load-suspension means is inserted in the supporting arm (1) in a loop with a C-shaped bay (6b) and extends along the telescopic arm in a channel (20) open to the outside. The hydraulic lines are well protected by these measures during the retraction and extension movements of the telescopic arm in the supporting arm.
