  • Coupling device for connecting an implement to a working machine
    Patent number: 6196595
    Abstract: A coupling arrangement for coupling a working implement to a working machine and being of the kind in which the two coupling parts are mutually connected both mechanically and hydraulically with no manual handling of the coupling arrangement. The machine-mounted coupling part has a drive means for moving associated hydraulic coupling connection means into coupling engagement with hydraulic coupling means on the implement-mounted coupling part, when coupling the machine and implement. The hydraulic coupling connection on the implement-mounted coupling part is movable in the direction of maneuvering movement of the hydraulic coupling, and is moved by the drive means via the hydraulic coupling connection on the machine-mounted coupling part until coming into abutment with an abutment means on the machine-mounted coupling part. The arrangement includes springs that function to exert a pressure that is opposed to this movement.
