WORK TOOL COUPLING ARRANGEMENT

摘要

A coupling arrangement (4) for coupling a work tool (3) to a machine (1) is disclosed. The coupling arrangement has a locking arrangement (13) for locking the work tool to the machine. The coupling arrangement further has at least two fluid couplers (21,22) arranged to be connected to each other for establishing a fluid passage between a main pressurized fluid circuit channel of a work tool and a main pressurized fluid circuit channel of a machine. The coupling arrangement further has a driving arrangement for driving at least one of the fluid couplers for connection to the other fluid coupler, the driving arrangement being separate from the main pressurized fluid circuit.
