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.

A detachable gooseneck trailer ( ) having a gooseneck ( ) and a detachable trailer deck ( ) utilizes a trailer attachment assembly ( ) to draw the trailer deck ( ) toward the gooseneck ( ) during attachment. The attachment assembly ( ) includes a pivoting carrier ( ) having a retainer leg ( ) with a rearward facing load carrier engagement surface ( ). A slide member ( ) is attached to the trailer deck ( ) and provides a forward facing slide member engagement surface ( ). As actuators ( ) pivot the carrier ( ) rearward, the load carrier engagement surface ( ) slides over the slide member engagement surface ( ). A latching mechanism ( ) utilizes an elongated latch plate ( ) pivotally mounted on the retainer leg ( ) to automatically latch the carrier ( ) to the trailer deck ( ). A latch biasing spring ( ) biases the latch plate ( ) toward its latched position, so that it automatically engages a catch ( ) mounted on the trailer deck. A lift mechanism ( ) utilizes lift actuator arms ( ) extending from the tops of the load carrier ends ( ) to push down carrier arms ( ) and support the gooseneck ( ) above the ground. A ride height lock assembly ( ) includes a pair of pawls ( ) and a pair of ratchets ( ) to lock the trailer deck at a desired ride height.

Cam action detachable gooseneck trailer

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. The bed-supporting undercarriage of the trailer may be moved from a rearward, road traveling position to a forward tilt position for decreasing the slope angle necessary to bring the rear end of the bed into engagement with the ground.

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.
