ABSTRACT:
A suspension system for wheeled vehicles which allows the body or frame of a vehicle, such as a trailer, to be lowered or tilted. The suspension system includes an off-set axle which, when rotated, adjusts the clearance beneath the wheeled vehicle so that the body or frame thereof can be lowered or tilted. The off-set axle includes a central portion which can be rotated by applying tension to a tensioning member attached thereto. In one embodiment the tensioning member is coupled to a shuttle which in turn is detachably coupled to another tensioning member that can be detached from the shuttle and used to pull a load onto the vehicle. The shuttle can be used to transfer tension between the tensioning members and lock the axle into a desired position.
