摘要

The holder (1) has guides i.e. carriage, longitudinally displaced with respect to arm parts. The longitudinally displaceable guides are provided at a dipping arm (10) of an extension arm and at the arm parts, and a drive is provided for the guides. The longitudinally displacement of the guides causes force to bring hose connections (12-15) of hydraulic lines (2-5) at hinge points between the arm parts and/or between the dipping arm and a coupling part or a work piece (21). The guides are provided for displaceable guiding of the hydraulic lines in a longitudinal direction of the arm parts.
