Abstract

A swivel hook assembly which comprises a hook unit that supports a hook which facilitates suspending a desire piece of equipment from the swivel hook assembly. The hook unit is engageable with a free end of a wire cable that controls vertical and horizontal movement of the hook unit. A hook coupling has an upper end which engages with a jib and a second end for engaging with the hook unit. When the hook unit is spaced away and disengaged from the hook coupling, the hook unit is rotatable relative to the hook coupling. However, when the hook unit is moved, by the wire cable, into engagement with the hook coupling, relative rotation between the hook unit and the hook coupling is prevented and more precise control over the suspended desire piece of equipment is achieved by the operator.
