Power coupling mounting for a quick-disconnect coupling on a heavy-duty machine

摘要

A power coupling mounting for a quick-disconnect coupling between the boom and stick on a heavy-duty machine having coupling elements to connect a power supply from the machine to the stick that eliminates the need for one or more persons to manually connect or disconnect the coupling elements when the quick-disconnect coupling is coupled or uncoupled. The quick-disconnect coupling includes a coupling member mounted on the boom of the machine and a coupling member mounted on the stick. The power coupling includes a male coupling element mounted on the stick coupling member and a female coupling element mounted on the boom coupling member. The female coupling element is slidably mounted on a plate extending from the boom coupling member for orbital movement and the male coupling element is gimbally mounted on a plate extending from the stick coupling member to facilitate alignment of the coupling elements along the X, Y and Z axes during coupling and decoupling of the coupling members.
