Crane arm for use in e.g. truck trailer, has lift and bent arms connected by articulated joint that includes pivot bearings at distance along rotational axis, where conduits run from lift arm to bent arm between pivot bearings

摘要

The arm has a lift arm (2) and a bent arm (3), where the lift arm and the bent arm are connected by an articulated joint (9). Conduits (10) are guided from an inside of the lift arm to an outer side of the bent arm. The articulated joint includes pivot bearings (9A) at a distance along a rotational axis. The conduits run from the lift arm to the bent arm between the pivot bearings.
