ABSTRACT:
A coupler includes a first hook assembly comprising a first hook adapted to receive a first associated attachment pin and a second hook assembly comprising a second hook adapted to receive a second associated attachment pin. The second hook assembly selectively pivots under force of an actuator relative to the first hook assembly by an actuator. The actuator comprises a screw jack that includes a locking sleeve to prevent unintended rotation of the screw member. Alternatively, the coupler includes a locking cam that moves between a retracted position and an extended position and a supplemental lock that selectively prevents movement of the locking cam from the extended position to the retracted position, and the actuator is operatively coupled to the second hook assembly and the locking cam.
