ABSTRACT:
A utility trailer has a frame which may be lowered to ground level at both the front and rear portions of the trailer to permit easy access and to facilitate loading and unloading of heavy vehicles or other items. The trailer frame is attached to a U-shaped axle which in turn is connected to a wheel suspension support. The wheel suspension may be raised or lowered by rotation of the wheel suspension about the axle allowing the rear of the trailer frame to be raised or lowered. The front of the trailer frame is connected to a cable controlled by a winch which will permit the lowering or raising of the front part of the trailer frame. Locking pins are employed to lock the suspension and the front portion of the trailer frame in place during travel.
