<p>A coupling assembly (10) for detachably attaching an implement having first and second link pins to a hydraulic arm of heavy machinery. The coupling assembly (10) has a first pair of parallel load transmitting plates (13, 14) interconnected by a transverse plate (15) and a second pair of parallel load transmitting plates (20, 21) interconnected by an end plate (36). Each first load transmitting plate (13, 14) has apertures enabling attachment by hinge pins (18, 19) to the hydraulic arm. The coupling assembly (10) has two recesses (22) engagable with the first link pin, a hook assembly (12) having hook members (24, 25) engagable with the second link pin. The assembly (10) also has indicator members (34, 35) which pivot with the hook members (24, 25) and extend through openings (37, 38) of the end plate (36) when the hook members (24, 25) have disengaged the second link pin. The indicator members (34, 35) in this extended position serve as a warning that the second link pin has been disengaged.</p> |
