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.

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. If the tail is to be raised to dock height, the undercarriage is pulled forwardly until the forward termination of its lost motion segment of travel is reached, whereupon an air bag is actuated to elevate a lifting strut member into an enabled position in contacting engagement with the underside of the tail.

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 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.

A detachable gooseneck trailer (20) having a gooseneck (24) and a detachable trailer deck (22) utilizes a trailer attachment assembly (30) to draw the trailer deck (22) toward the gooseneck (24) during attachment. The attachment assembly (30) includes a pivoting carrier (66) having a retainer leg (84) with a rearward facing load carrier engagement surface (90). A slide member (68) is attached to the trailer deck (22) and provides a forward facing slide member engagement surface (94). As actuators (70) pivot the carrier (66) rearward, the load carrier engagement surface (90) slides over the slide member engagement surface (94). A latching mechanism (34) utilizes an elongated latch plate (122) pivotally mounted on the retainer leg (84) to automatically latch the carrier (66) to the trailerdeck (22). A latch biasing spring (124) biases the latch plate (122) toward its latched position, so that it automatically engages a catch (126) mounted on the trailer deck. A lift mechanism (36) utilizes lift actuator arms (148) extending from the tops of the load carrier ends (74, 76) to push down carrier arms (144) and support the gooseneck (24) above the ground.
