Abstract

The trailer chassis includes a plurality of frame members forming a substantially rectangular box frame. The rectangular box frame includes a central, elongate main sub-frame integral with a pair of spaced outboard frame rail sections where wheel wells are formed. The central main sub-frame is devoid of cross members to provide unhindered storage space. Select sections of the rectangular box frame are covered with rigid plating to strengthen the torsional rigidity of the trailer chassis. The front section of the rectangular box frame includes a raised platform with a hitch frame integral thereto for installing a hitch. The trailer chassis is detachably mounted to the trailer in order to permit separate shipment of the trailer chassis in a shipping container.

Claims

1. A trailer chassis, comprising:

an elongate, substantially rectangular box frame formed by a plurality of rectangular tubing members, the rectangular box frame having;

an elongate, central main box sub-frame having an unhindered basement area along the length thereof and at least a top deck;

an elongate frame rail section on each lateral side of the main box sub-frame and integral therewith, each of the frame rail sections having a wheel well and a top contiguous with the top deck;

a front hitch section extending upwardly from the top deck, wherein the front hitch section comprises;

an upwardly extending, polygonal box sub-frame, the polygonal box sub-frame having spaced polygonal sides and a sloping front contiguous with the polygonal sides forming a raised platform; and

a hitch sub-frame extending from the raised platform; and

flooring covering the top deck and the top of the lateral frame rail sections; and

reinforcement members on select segments of the rectangular box frame to increase structural integrity thereof.

2. The trailer chassis according to claim 1, wherein said reinforcement members comprise plating covering the select segments of the rectangular box frame.

3. The trailer chassis according to claim 2, wherein each said wheel well of the frame rail sections comprises a rectangular box sub-frame covered on at least three sides with plates to form an opening for wheels.

4. The trailer chassis according to claim 2, wherein uncovered segments of the frame rail sections form discrete storage compartments.

5. The trailer chassis according to claim 1, wherein said reinforcement members comprise plating covering the select segments of the rectangular box frame, the polygonal sides and the front of said front hitch section being covered with plates.

6. The trailer chassis according to claim 1, wherein said reinforcement members are disposed at alternate segments of the rectangular box frame to increase torsional rigidity.
