A hitch and adapter assembly for connecting an implement to the front end of vehicles such as all terrain vehicle providing a rigid connection with limited motion for reduced vibration operation. The hitch has two spaced apart sockets on a rigid frame that pivotally connects to the vehicle providing a rigid extension thereof. The sockets receive and cooperatively engage respective pins on the implement providing a quick connection. An electrically powered hydraulic cylinder is connected at one end to the frame and the other end connects to the vehicle by a coupler that slip fits into a socket therefore on the vehicle. The frame pivotally connects to the vehicle at two spaced apart positions. There is a coarse and fine adjustment for varying the height and tilt positions of the implement.

A trailer reversal self-correcting assembly (10) adapted to be disposed between the tow bar (12) of a vehicle (14) and the tow member (16) of a trailer (18), the assembly (10) comprising a tow arm (20) pivotally connected to the tow bar (12) at its first end and to the tow member (16) at its second end, a first extension mount (26) extending laterally from the tow bar (12), and a second extension mount (30) extending laterally from the tow member (16), a first correcting linkage device having at least a first linkage member (38) connected between the first extension mount (26) and the second extension mount (30).

A bumper system for a vehicle comprises a beam having a face and having mounts adapted for mounting to a vehicle frame, and an energy absorber engaging the face and having end sections located outboard of ends of the beam, the energy absorber being made of a structural engineering polymeric material and the end sections having flat top surfaces for forming steps outboard of the ends of the beam.

A liquid storage tank includes a vessel comprising sidewalls, end walls, a floor and a roof that define a closed interior cavity within the vessel, with at least a first of the sidewalls of the vessel having a multi-walled construction comprising an interior wall and an interior wall. The tank further comprises a manway assembly in the first sidewall. The manway assembly comprises exterior and interior openings and exterior and interior doors for closing the exterior and interior openings, respectively. The exterior and interior openings and the exterior and interior doors are arranged relative to each other and the interior door is sufficiently small so that while the exterior door is open the interior door can be opened by pivoting the interior door into the exterior opening.

A front tow extended saddle is disclosed. The saddle allows a first towing truck to mount a second truck, facing forward, behind the first truck, in order to tow the second truck to a distant location. The saddle allows the towed truck to face forward during transport, thus allowing for the normal loads and stresses of movement on the towed truck. This configuration is preferable to movement with the towed truck facing-rearward, in which the typical aerodynamic surfaces of a large truck act as a drag during transport, imposing high wind loads and unusual stresses. The front tow extended saddle is also designed to minimize the required vertical rise on the towed truck, which also avoids additional stresses during loading and unloading onto the towing truck.

A front tow saddle including a tie-down assembly for connecting with one or both of the spring and spring shackle of a towed truck.

A roll-off tub style container which is leak-proof to prevent liquids in the container from draining onto the ground or roadways. In one embodiment of the invention, the floor of the container has an upwardly and rearwardly extending inclined portion at the rearward end thereof to prevent liquid in the container from coming into contact with the tail gate of the container. In another embodiment of the invention, the rearward end of the container is elevated during transport to prevent liquid in the container from coming into contact with the tail gate. In yet another embodiment of the container, the floor of the container is inclined upwardly and rearwardly from the forward end thereof to the rearward end thereof. A liquid collection tank may be positioned beneath the floor of the container which has an inlet in fluid communication with the interior of the container and a discharge outlet provided thereon to permit liquid in the tank to be selectively drained therefrom.

A wall surface suction travel device includes a first travel unit, a second travel unit, a joint mechanism, and an elastic mechanism. The travel units are aligned along a travel direction and are each configured to travel on a wall surface while being suctioned on the wall surface. The joint mechanism couples the travel units together such that the travel units can pivot relative to each other on a pivot axis extending in a direction that is perpendicular to both a wall surface facing direction and the travel direction. The elastic mechanism includes a first end fixed to the first travel unit, a second end fixed to the second travel unit, and an elastic member configured to be elastically deformed when one of the travel units pivots relative to the other travel unit and a distance between the first end and the second end is shortened.

The invention relates to a trailer towing-control apparatus comprising a towing means connectable between a trailer and a towing vehicle; the towing means having a first connection means at its operative forward end pivotably connectable to a towing vehicle and a second connection means pivotably connectable to the trailer on the other side of the axis of the trailer relative to the first connection means; and a restraint means to selectively allow for articulation of the first connection means relative to the towing vehicle or to prevent articulation of the towing means relative to the towing vehicle in a horizontal plane.
