Abstract: A kingpin stabilizer having a kingpin-retaining bracket having a base plate and upwardly extending walls along at least two sides of the base plate. The upwardly extending walls and the base plate forming a receiving cavity with the upwardly extending walls spaced apart to fit said kingpin therebetween. At least one upwardly extending wall has a pin retainer. The stabilizer includes three telescoping legs extending from the pin-retaining bracket forming a tripod.

Abstract: A coupling aid facilitates connecting at least one supply line between a first vehicle and a second vehicle which can be coupled to the first vehicle by means of a coupling. The coupling aid comprises a supply bracket mounted on the second vehicle and used to receive the at least one supply line. The supply bracket can be moved by means of a drive from a driving position (A) in the longitudinal centerline of the vehicle into an operating position (B) lateral to the driving position. The coupling is provided with at least a first sensor for detecting the locking state of the coupling and the movement of the supply bracket is triggered by a signal from the first sensor.

Abstract: A rotational jack assembly is provided to support a portion of a trailer. The jack assembly has a pivot mount with a pivot axis, a mounting plate rotatable about the pivot axis and a pin receptor with a first and second portion. The mounting plate carries a support assembly and a locking pin. The locking pin is engagable with the pin receptor, and adapted to move between the first and second portions of the pin receptor upon application of rotational force. A force activated locking assembly and a breakaway support assembly are also provided for supporting a portion of a trailer. A method of use for the rotational breakaway trailer jack assembly is also disclosed.

Abstract: The present invention provides a non-articulating low load platform trailer longitudinally divided into three load carrying segments; a rear load platform, a front coupling platform, and an inclined transitional platform between the coupling platform and the load platform. The trailer of the invention includes a self-contained power actuated lifting mechanism for the purpose of lowering the nose of the trailer to the ground without articulation of the trailer body to facilitate loading and unloading, and for the purpose of raising the nose of the trailer from the ground. The lifting mechanism includes lever arms configured to increase the vertical component of lifting force exerted by lift actuators, and further includes leverage links disposed between the lift actuators and lever arms for the purpose of further increasing the vertical component of lifting force when the nose of the trailer is near the ground.

Abstract: An apparatus is set forth to vary the wheel base configuration of a tractor-trailer apparatus, wherein the trailer is positionable upon a carriage mounted upon "C" shaped channel guide rails mounted on the framework of a tractor organization. The rails include a reciprocating carriage mounted thereon for engagingly latching and reciprocatingly positioning and securing the trailer relative to the tractor framework, whereupon retraction of the carriage simultaneously secures the trailer to the tractor and elevates the rear tractor wheels out of contact with an associated roadway. An electrical interlock is provided for indicating proper orientation of the trailer relative to the tractor.

Abstract: A trailer having a front undercarriage assembly including lower members or "feet" that are adapted to automatically retract when the trailer is coupled to a tractor. Direct mechanical linkages are provided throughout the retracting mechanism to insure positive operation of the apparatus. In addition, a novel latching mechanism is disclosed that is adapted to automatically lock the vehicles in the coupled position and permit convenient disengagement of the trailer from the tractor.
