LOAD CARRIER WITH ELEVATABLE LOAD ENGAGING SURFACE

摘要

A towed vehicle including two wheeled units normally spaced apart by a reach pole and capable of being moved towards and away from each other when loading a load carrying body or unloading a load carrying body. Each wheeled unit includes a frame structure and an axle and wheel assembly pivotally supported therefrom. Air bag units interconnect the axle and wheel assembly and the frame for varying the elevational position of the load supporting surface on the wheeled units. A self-contained pressure tank is provided for enabling adjustment of the load carrying surface independent of any towing vehicle.
