ABSTRACT:
A coupling for a heavy-duty machine to be used between a boom and a stick having a working tool for quick coupling and decoupling of the stick to the boom for the exchange of tools and being operable from the cab or operator's station on the machine without requiring the need for one or more persons or machines at the coupling during the coupling and decoupling process. The coupling also includes a unique locking mechanism that can be remotely controlled to lock and unlock the coupling when they are in mating engagement. The coupling includes a male member attachable to the boom of the machine and a female member connected to the stick. The male member is pivotally mounted at one end on the boom and connected at the other end to a hydraulic cylinder on the boom for articulating the male member on the boom. The male member further includes a grabber at one end and a picker at the other end for interchangeable use to guide the joining of the coupler members. The male and female members are symmetrically constructed so that either end of one member may be aligned with either end of the other. The coupling also includes a unique locking mechanism that can be remotely controlled to lock and unlock the coupling when they are in mating engagement. Further, the coupling includes unique hydraulic couplings for connecting a source of hydraulic power from the machine to the stick that may be just mated together or provided with remotely operable locking structure.
