A trailer is provided having a frame (2) upon which a bed (3) slides. The frame (2) has a wheel and axle assembly (1) and (5) disposed thereon which is connected thereto by a spring hanger assembly (6). The spring hanger assembly (6) is comprised of a spring and axle assembly (17). A tongue and coupling (7) is provided for connecting one end of the bed (3) to a vehicle. The bed (3) slides relative to the frame (2) when the wheels (5) are locked and the tongue assembly (7) pushed rearward. The bed (9) tilts when the rearmost portion moves the center of gravity away from the wheels (5). The end of the bed (3) will contact the ground, allowing loading on the surface thereof.

A self-loading trailer, comprising: a stationary frame having an upper surface; a loading bed having an upper surface that comprises the loading surface and a lower surface that is disposed in a sliding relationship with the upper surface of said stationary frame, said loading bed being longer in one direction than said stationary frame, said loading bed having two positions relative to said stationary frame, a resting position and a loading position, said loading bed in the resting position having the rearmost end moved toward said stationary frame and, in the loading position, having the rearmost end extended outward from said stationary frame; locking means for locking said loading bed to said stationary frame to prevent sliding relative thereto when said loading bed is in the resting position; a connecting device being disposed on the forwardmost end of said loading bed for pulling and pushing said loading bed with a vehicle; first and second wheels on either side of said stationary frame; suspension means associated with each of said first and second wheels on either side of said frame, each of said suspension means on each side of said frame being in an adjacent relationship with the other and disposed about the rotating axis of said associated first and second wheels on each side of said stationary frame, each of said suspension means supporting said stationary frame at two associated suspension points proximate to the lower surface of said stationary frame on either side of the rotating axis of said associated first and second wheels on either side of said frame and also supporting the rotating axis of said associated first and second wheels on either side of said frame, at least the adjacent ones of the associated suspension points disposed such that one is forward of the other and said adjacent suspension means not overlapping, with the first and second wheels on either side of said frame being compressible with respect to the lower surface of said frame such that when the rearmost end of said loading bed is in the loading position, the weight of said loading bed rearward of said first and second wheels on either side of said frame suspension means causes more compression of the rearmost one of said adjacent suspension points relative to the forwardmost one thereof to allow tilting of said loading bed and said stationary frame; and brakes associated with at least one of said first and second wheels on either side of said frame for preventing rotation thereof when said connecting device has a force associated therewith directed in the rearward direction and said locking means is disengaged to allow said loading bed to be reciprocated backward relative to said stationary frame from the resting position to the loading position and, alternatively, to be moved forward in a sliding relationship from the loading position to the resting position, a rearward directed force causing further compression of the rearmost one of said adjacent suspension points, said rearmost ones of said suspension means operable to further compress in response to rearward forces.
