Quick coupling for heavy equipment attachment

摘要: A quick coupling for attaching implements to heavy equipment includes a coupler that is rotatably attached the stick and implement linkage of boom at attachment axes are oriented preferred geometric relationship particular piece equipment. The releasable attachable bracket implement. Thus, interchangeably having different relationships between their axes. Bosses located on coaxially with axis rotation received in conforming receptacles formed bracket. wedge movable tracks defined upon activation piston cylinder engages cam surfaces element pull toward when pulled downwardly. Mating cause bosses be urged into coupler. firmly couples elements even they have started experience wear. Springs normally bias downwardly so device will not become uncoupled loss hydraulic pressure. drilled receive bolts fit threaded bores coupler, which allows coupled manually if desired.
