QUICK COUPLER WITH HYDRAULIC COUPLING MANIFOLD

Abstract:

A coupling assembly for releasably mounting, and hydraulically coupling, a tool to a work machine. The coupling assembly includes a mount attachable to the work machine and configured to receive the tool in a mounted position of the tool, a rigid retaining body movable in translation relative to the mount along a translation axis between a retaining position for retaining the tool to the mount and a release position for releasing the tool from the mount, a first and a second actuator operable to move the retaining body between the retaining and release positions, and a hydraulic coupling manifold movable in translation relative to the mount along the translation axis for hydraulically coupling the tool to the machine, wherein the hydraulic coupling manifold uses the first and second actuators as guides for moving along the translation axis.
