Abstract

Hydraulically operable coupling device for connecting and disconnecting the boom of an equipment item such as an excavator, loader or the like, in particular an articulated arm of a hydraulic excavator, to and respectively from an implement such as a bucket or the like, comprising a coupler element, which is linked to the free end section of the boom at a pivot pin, can be pivoted by means of an actuating device relative to the boom and at one of its ends is to be brought into positive-locking engagement with first coupling elements arranged on the outside of the implement, and a wedge-shaped or tapered locking element which is arranged at the other end of the coupler element, is guided parallel to the pivot pin and can be actuated by a hydraulic piston/cylinder arrangement and by means of which the coupler element is to be connected to the implement with positive locking free of play via a second implement coupling element reaching in the coupling position into the path of movement of the locking element, the locking element (12) being the wedge-shaped or tapered cylinder of the piston/cylinder arrangement (13) actuating the locking element (12), the cylinder (12) of the piston/cylinder arrangement (13) being axially displaceable, while its piston rod (14) is mounted in an axially fixed manner on the coupler element (6). <IMAGE>
