Abstract
An adjustable height jib is disclosed for an arm of a hook-lift hoist for loading of equipment, containers or the like onto a truck for transport. The jib has an elongate body with a hook located on each of its opposing end portions. The jib is mounted on the arm for pivotal movement between a first position for loading containers of a first height and a second position for loading containers of a second height. A lock secures the jib in either position. A feature of the adjustable height jib is that, upon release of the lock, it will pivot between a longer position as the hook-lift hoist is operated toward the loading position and a shorter position as the hook lift hoist is operated toward the transport position.
