Abstract: 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.

Abstract: A locking mechanism for a quick-connect/disconnect coupling for a heavy-duty machine including a boom and a stick to facilitate the interexchangeability of work tools wherein the locking mechanism can be remotely controlled to lock and unlock the coupling members when they are in mating engagement. The coupling includes a male member attachable to the boom of the machine and a female member attachable to the stick. The locking mechanism includes a pair of planetary gear assemblies, a motor and a brake that drive and maintain a pair of wedge shaped bars within their respective sockets. The coupling also includes proximity sensors to facilitate the proper engagement of the coupling members.
