Abstract:

A load hook assembly includes an upright support structure adapted for cable attachment to a lifting instrumentality such as a helicopter. A jaw assembly, carried by the support structure, has multiple, movable jaws which open and close relative a centrally disposed, fixed jaw. Each movable jaw is independently operated by an air cylinder coupled to a jaw associated toggle linkage. The movable jaws and the central, fixed jaw are spaced from one another when closed to permit lateral insertion of a ferrule on a load engaging choker cable. Each movable jaw is controlled in a remote manner by an operator to permit selective release of one or both loads. A method of load transport is also disclosed.
