ABSTRACT:
Earthmoving vehicles are often provided with quick coupling devices that allow them to change work implements in a relatively rapid fashion when compared to changing conventionally mounted implements. In most cases, the performance of the work implement is sacrificed to accommodate the ability to change implements quickly. In other cases the level performance is satisfactorily maintained, but the actuation of the coupling mechanism must be done manually or has no ability to accommodate loosening between the coupler and the work implement that can result from normal operation. The coupling device of the present invention allows an operator to change implements from his position within his operating station, yet maintain a structure that will not sacrifice the performance of his work implements through alteration of the linkage arrangement or through the additional weight. The locking means between the coupler and the implement are positioned for the optimum transferal of force between the components and includes a means which will continually take up any loosening that may occur through wear or operational loading.
