Abstract: A semi-trailer includes first and second main beams and left and right side rails. A cargo platform extends between the left and right side rails. Each of the side rails includes an aluminum extrusion including an upper portion including a platform engaging portion, and a lower portion including a winch track. The lower portion further includes a projecting hook engagement wall. The hook engagement wall includes an upper surface oriented toward the cargo supporting platform and an opposite lower surface. The hook engagement wall includes a tapered nose including first and second nose walls that define a nose angle X such that said tapered nose is adapted to be received in an open recess of an associated cargo strap hook that defines a hook recess angle X?.

Abstract: A working vehicle where a front axle case is supported by two front axle brackets includes a body flame formed by disposing beams at a prescribed interval, by welding reinforced plates to plate faces of the beams which face to each other, and by welding both end parts of one of the front axle brackets to the reinforced plates; and a front hitch formed by welding both end parts of the other front axle bracket to both end parts of a plate member which are bent. The front hitch is attached to the body flame such that the two front axle brackets are opposed to each other.

Abstract: The present invention provides an integrated composite floor unit and front wall assembly that can be used in a variety of structures. The integrated composite floor unit and front wall assembly is formed of a floor unit having a front portion and a front wall integrally formed with and rising up from the front portion of the floor unit. The assembly can include other structural features and may be easily combined with a number of further structural components to form a structure. In specific embodiments, the assembly forms part of a modular trailer. In particular, the trailer can be formed of the composite assembly, a composite roof, composite side walls, and a composite rear frame. Such composite trailers advantageously provide a storage volume approximately equal to or greater than conventional trailers but are lighter in weight, thus allowing for storage and/or hauling of a greater weight of cargo than in conventional trailers.

Abstract: A universal wheel seat includes a chassis and a rotor that is composed of an inner seat, an outer seat and several balls. A fixing bolt is inserted through the chassis and the inner seat to firmly combine the chassis and the rotor together. By so designing, different-sized chassis and rotor can be optionally paired and assembled together by the fixing bolt in accordance with a customer's need.

Abstract: A tractor having a front end and a rear end adaptable for a variety of different environments. Methods related to the conversion of the tractor are also disclosed. In one embodiment, the invention includes a front wheel assembly that is removably attached to the front end of the tractor to facilitate adaptation of the tractor a various environments. Also, a steering actuator is removably attached to the front wheel assembly and fixedly attached to the chassis of the tractor.

Abstract: A system for automatically and simultaneously controlling one or more vehicle functions by detecting the direction of movement of and the distance traveled by the vehicle. The control system includes an electronic sensor mounted on a selected one of the vehicle axles adjacent to and facing an anti-lock braking system tone ring of a selected one of the wheel hubs mounted on the axle. The sensor is electrically connected to an electronic control unit, which in turn is electrically connected to a vehicle function actuation device such as a lift axle solenoid or back-up alarm actuation device. The sensor transmits direction and distance information to the electronic control unit based on the movements of a plurality of teeth formed on the tone ring. The control system is a stand-alone system that is free of interfacing with other vehicle systems, such as the anti-lock braking system.

Abstract: A running gear includes an axle assembly of a first type and an axle bracket hanger pair mounted to the first type of axle assembly and being capable of having multiple axle assembly types mounted thereto. A trailer includes an axle assembly of a first type, an axle bracket hanger pair mounted to the first type of axle assembly and being capable of having multiple axle assembly types mounted thereto, and a bed attached to the axle bracket hanger pair. A method includes providing an axle bracket hanger pair capable of having multiple axle assembly types mounted thereto, selecting an axle assembly from the multiple axle assembly types, and mounting the selected axle assembly to the axle bracket hanger pair.

Abstract: The present invention provides an axle mounting arrangement for mounting an axle assembly to the frame of a vehicle. A plurality of attachment structures are provided on the frame, and at least one support structure is provides for coupling the axle assembly with the attachment structures at different locations along the frame.
