Locking system for quick coupler

Abstract

A quick coupler for holding an implement is disclosed. The quick coupler includes a frame having a first plate and a second plate. The quick coupler includes a locking system adapted to lock the implement in the first plate and the second plate. The locking system includes a securing latch member and a hydraulic actuator is operatively connected to the securing latch member. The securing latch member is configured to move along a guide provided in each of the first plate and the second plate. The locking system further includes a set of grooves provided on at least one of the securing latch member and the guide. The set of grooves are adapted to lock the securing latch member in a latched position.
