Abstract: A fixture to be used in conjunction with a standard engine crane for the hoisting of fleet-bed truck bed is disclosed and claimed. The fixture comprises a pair of struts joined at their center by a cross member, thus forming an I-shaped structure. At the end of each strut is an adjustable extension arm assembly, configured so that the I-shaped structure may be lowered into the truck bed, adjusted for a snug fit, and the adjustments fixed and secured. One or more brackets are located on the I-structure, so that a chain or other device may be fastened between the I-structure and engine crane, allowing a single operator to perform all the manipulations required to easily and safely lift the truck bed off the truck chassis.
