In logging and other handling operations, a cable is often looped about the elongated object and cinched tight through a choker hook assembly in order to transport the objects. A remotely controlled hook assembly has a body, including an eye for the passage of the cable and a releasable latch arm for grasping the end of the cable. Encased within the body is a slidable pin that serves to lock the latch arm and therefore the end of the cable. A positioning device is also within the housing and serves to rotate a catch member allowing the slidable pin to move downwardly, thereby releasing the latch arm and cable. A pair of appropriately sized and located springs serve to both move the sliding pin downwardly and to bias the pin upwardly. A radio controlled servo may be used as the positioning device. |
