Abstract
There is disclosed a vehicle having a load bed which has a back end that is supported by a wheel set which has a frame that is pivotally mounted below the back end and has extensible air bags connecting the frame to the back end of the load bed. The air bags are extensible to raise the back end to a raised position with respect to the frame and retractable to lower the back end to a lowered position. Included are non-compliant legs arranged to extend between the frame and the back end of the load bed when the back end of the load bed is in the raised position and a releasable locking operable to lock the legs in a locked position in which it serves to hold the back end of the load bed fast in the raised position. The lock is releasable to allow the load bed to be lowered to the lowered position. The air bags extend across the back end of the chassis to give high surface area contacts between the air bags and the frame of the load bed and wheel set frame.
This high surface area results in a much lower air pressure being required to raise the load bed than is required in hydraulic systems where the cross sectional area of the piston is much smaller.
This high surface area results in a much lower air pressure being required to raise the load bed than is required in hydraulic systems where the cross sectional area of the piston is much smaller.
