Abstract
Damage to a hook lift type of container handling system caused by torsional loading of a jib slidable within a tube or the like pivotably mounted on a frame carried by a vehicle is minimized by providing a secondary frame that is pivoted to the vehicle and which is made up of two spaced, parallel, tubular structures and a jib made up of two, parallel tube like structures telescopically, slidably received in the tube like structures of the second frame. The jib includes an upstanding hook and by reason of the spacing between the two tubes of both the jib and the secondary frame, a high resistance to torsional loading is provided, thereby eliminating damage as a result of torsional forces.
