    Abstract: A dump trailer comprising a U-shaped trailer body having a bottom wall and opposing side walls. The trailer includes a curved front wall and a pivotable tailgate. The front wall is U-shaped when viewed from the top and angles upwardly and forwardly from the bottom wall. A support structure provided adjacent the front wall operatively engages hitch and lift assemblies. The support structure includes spaced-apart supports secured to the front wall; and spaced-apart horizontal beams secured to the supports. The beams extend through apertures in the front wall and into the compartment. This enables the trailer body to be lowered relative to the ground, thus lowering the center of gravity of the trailer. A wheel assembly mounts to the rear end of the trailer via a mounting plate curved complementary to the bottom wall. Cut-outs in the plate reduce the overall weight of the trailer.

    Abstract: A lockable center door assembly for a dump trailer is provided. A frame is mounted in a wall of the dump trailer and has a pair of opposite and spaced apart channels. A retractable door has a pair of edges slidably received in the frame. A pivot linkage assembly is operatively connected to the door for linearly moving the door between the closed and open positions. A locking assembly movable between an engaged position and a disengaged position is operatively connected to the pivot linkage assembly for securing the door in either the closed or open position.

    Abstract: A retractable step assembly for a vehicle includes a track assembly mounted on a vehicle frame beneath a workbed, a step assembly, and a pivot assembly that engages the track and step assemblies together. The step assembly moves between a storage position where it is disposed between tracks of the track assembly, and an operational position where it extends outwardly from the tracks, through an aperture in the vehicle's wall panel, and angles downwardly toward the ground. A foldable handrail on the step assembly is selectively movable between a collapsed position and an extended position. The handrail is in the extended position when the step assembly is operational and folds to the collapsed position when the step assembly is stored. First and second supports are provided for the step assembly to rest upon when in either of the storage position and the operational position.

    Abstract: An air fairing device is connected below the bottom a frameless trailer to improve aerodynamic efficiency and improve fuel economy. One embodiment of the air fairing device provides an air deflector positioned forward of a trolley which supports the frameless trailer at a rear end. A second embodiment of the air fairing device provides two deflectors mounted below the frameless trailer. The first deflector is attached and extends downward from an articulating arm, said arm connecting the trailer to a semi-tractor or truck. The second deflector connected to below the bottom of the frameless trailer and positioned rear of the first deflector and forward of the trolley. A third embodiment is similar to the second but further includes a third deflector positioned between two axles of the trolley.

    Abstract: A drop deck trailer frame includes a front section having a first upper surface, a rear section having a second upper surface lower than the first upper surface, and an improved connection between the front and rear sections which tends to reduce cracking which commonly occurs in drop deck trailer frames due to the stresses in the region of the connection. The connection preferably includes a semicircular weld. In addition, heat treated bent flanges are typically used to provide additional strength. Fasteners such as bolts are also typically used to connect various flanges.
