ABSTRACT:
An elevating trailer for moving between a low, cargo-loading position and an elevated, cargo-transporting position. The frame of the trailer has opposing sides, each side carrying a pair of tandem wheels. An inflatable air bag is mounted on a supporting and pivotal frame above the trailer side. When the bags are inflated the arms of the supporting frames are spread apart, lifting the frame. When the bags are deflated, the arms pivot toward each other, lowering the frame and facilitating loading of cargo into a container mounted on the trailer frame.
