ABSTRACT:
An improved hoist assembly 200 having a frame assembly 10 and a boom assembly 60 is described. The frame assembly is comprised of a box member 12 with channel member 12L having first and second holes 120 and 12P for mounting a first and second kingpin assembly 26 and 28. The second holes are spaced away from the first holes and allow for storage of the unused kingpin assembly. The box member has a lockable cover 12E which allows for storage of parts and other items directly within the hoist assembly. A boom 62 of the boom assembly is attached to the frame assembly and is protected on either side by cover plates 46 and 48. The boom is raised and lowered by a hydraulic pump assembly 74 electrically connected to an electrical system of a towing vehicle. A cross member support 66 supports a cross member 68 which is secured to an axle of a disabled vehicle by chains for towing the disabled vehicle. In an alternate embodiment, an underlift attachment 98 having an expandable cross member 112 with end bars 124 and 126, and legs 128 is positioned around the tires of the disabled vehicle to attach the disabled vehicle to the towing vehicle.
