ABSTRACT:
An adjustable height wagon capable of being manipulated between an orientation allowing maximum lift and an orientation allowing maximum height. The provision of a lift mechanism below an undercarriage of the wagon increases the stability of the wagon during lifting, and allows a material supporting bed to be drawn into contact with the undercarriage, thereby increasing the stability of both the material supporting bed and the wagon.
