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 self-loading tilt bed trailer has an elongated tiltable bed normally disposed in a substantially horizontal road traveling position that may be tilted about a transverse horizontal axis to a downwardly and rearwardly inclined position. The bed is pivotally coupled at its front end to a towing tractor for pivotal movement of the bed about a substantially vertical axis. When the bed is tilted steeply enough to raise the wheels completely off the ground so the weight of the bed is supported only by a ground-engaging pad at the rear of the bed and the tractor at the front, actuation of a hydraulic cylinder associated with the pad causes the rear of the bed to be shifted a short distance to the right or left relative to the stationary pad, pivoting about the upright hitch axis at the tractor.

Abstract: A structure for buckling the frames of a two-sectioned, centrally articulated truck chassis has a pair of links swingably mounted on the front frame and pivotally connected to a piston and cylinder power assembly carried by the rear frame. Additionally, a control member in overlying, vertical alignment with the piston and cylinder assembly swingably connects the links to the rear frame. As the piston is actuated, the force directly bears on the links, causing the latter to swing and simultaneously move the control member, causing the frames to move upwardly and spread while tilting about their articulation. The entire force presented by the rear mounted cylinder and piston assembly bears directly on the opposite, front frame such that a minimum amount of power is required to effect the tilting. Also, the vertical alignment of the piston and cylinder with the control member reduces bending and bowing stresses in the structure.
