Abstract
In logging and other handling operations a cable is looped about an elongated object and cinched tight through a choker hook assembly in order to transport the objects. A remotely controlled hook assembly has a body and a releasable latch arm through which the cable passes and which grasps the end of the cable. A recessed knob socket is located on the outside of the hook body for acceptance of the knob mounted at the cable end. Within the body a slidable pin functions to hold and then release the latch arm upon remote command. The slidable pin can be reset by using the pivotal latch arm in combination with the cable and knob as leverage.
