ABSTRACT:
A wheel lift head assembly is pivotally mounted adjacent the rear end of a truck frame and is hydraulically operated for raising and lowering one end of a vehicle to be towed behind the truck. The wheel lift head assembly includes a crossbar member having a pair of hollow tubes pivotally mounted at opposite ends thereof with a pair of J-shaped wheel engaging members slidably mounted therein. A retainer is secured to an end of each J-shaped arm to prevent the withdrawal of the arm from the pivoted guide tube and a J-shaped arm provides engagement on opposite sides of the wheels of the vehicle to be towed to prevent lateral slipping of the wheels. A tiltable truck bed is mounted on the truck for pivotal movement between a horizontal position and an inclined position. At least one support post is provided at the rear of the tiltable truck bed for supporting the end of the tiltable truck bed on the ground and notches are formed in a forwardly facing surface of the support post. A locking member is pivotally mounted on the wheel lift head assembly for pivotal movement into and out of engagement with a selected notch for locking the wheel lift head assembly in the raised position.
