Abstract: A vehicle transporter includes a frame with a load deck, a slidable undercarriage mounted on the frame and a subframe movably mounted on the frame between raised and lowered positions. Wheel wells are formed in the deck when the subframe is lowered relative to the frame. A pair of outrigger assemblies each includes a hydraulic piston-and-cylinder lift unit for raising and lowering the transporter whereby the undercarriage can be slid between fore and aft positions.

Abstract: The trailer has a deck assembly that includes a level main deck portion and a tail hinged to the main deck for vertical swinging movement between a level transport position, a downwardly and rearwardly inclined ground-loading position, and an upwardly and rearwardly inclined dock-loading position. Raising and lowering of the tail between such positions is carried out by fore-and-aft movement of the shiftable undercarriage of the trailer, such undercarriage being located under the tail and generally behind the hinge when the trailer is in its roading position with the tail in its transport position. When the undercarriage is shifted forwardly beyond a lost motion segment of travel, the tail is allowed to progressively descend by gravity to its ground-loading position. Returning the undercarriage to its roading position beneath the tail causes the tail to be raised back to its transport position.

Abstract: A self-loading trailer has a flat deck that can be raised and lowered between a horizontal transport position and a downwardly and rearwardly inclined loading position. A pair of winches adjacent the front end of the deck are normally maintained in a stowed position slightly inboard from opposite sides from the deck but can be shifted outwardly into extended positions outboard of the lateral confines of the deck. In such extended positions, the winches may be used to draw a first container up onto the deck as the inclined deck is moved rearwardly under the container, and then a second container behind the first container, without interfering with the first container. When both containers are fully loaded, the winches are retracted back into their stored positions.
