Abstract: The present invention provides an extendable telescoping boom having one or more telescoping sections which nest inside one another allowing the boom to extend and retract. Along the surfaces of the boom sections are one or more sunken pockets in the surface of the boom sections which contain one or more wear pads attached within one or more sunken pockets allowing the multiple boom sections to slide linearly one inside the other with a reduced gap between the boom sections. A method of manufacturing an extendable telescoping boom assembly is also provided.

Abstract: The current invention is a portable wheel lift device for lifting and towing vehicles comprising a boom which pivots up and down for connecting to and raising a portion of a vehicle which is to be towed. The invention comprises a mounting frame, a means for attaching the mounting frame to a towing vehicle and a two-stage cylinder assembly operatively connected to the mounting frame and the boom for tilting the pivoting boom relative to the mounting frame.

Abstract: A new adapter for attaching a wheel lift apparatus to a road tractor for quickly mounting wheel lift apparatus to the road tractor. The inventive device includes a mounting frame having a gooseneck configuration defining a wide end and a narrow end, with the wide end of the mounting frame mounted on the frame of the road tractor, and the narrow end attached to the fifth wheel plate of the road tractor by a kingpin and attached to the tractor frame by link rods.
