ABSTRACT:
A quick coupling apparatus for coupling a tool to a tool arm comprises a coupler member attached to the tool arm, and configured to engage a mounting bracket extending out from the tool. A wedge is mounted on the coupler member and is movable, when the coupler member and mounting bracket are engaged, from a closed position engaged in a groove on the mounting bracket to an open position where the wedge is removed from the groove. A wedge positioning mechanism selectively moves the wedge to the closed position and the open position. When the wedge moves into the groove and into the closed position, a remotely operated latch control moves a safety latch from an unlatched position to a latched position to prevent the wedge from moving toward the open position. The wedge positioning mechanism can be configured to utilize a single or double acting actuator.
