Abstract

A modular trailer system comprising a plurality of curved panels, where each panel is elongate and has a first side with an angled projection and an opposing second side with an angled slot such that the angled projection of one panel is capable of fitting into the angled slot of another panel, allowing the panels to join together to form a continuously curved surface. The modular trailer system may further comprise a first top rail with an angled slot capable of receiving the angled projection of one of the plurality of curved panels and a second top rail with an angled projection capable of fitting into the angled slot of another of the plurality of curved panels. The plurality of curved panels, first top rail, and second top rail may be assembled together to form an elongate trailer body with a partially circular cross section, such that the trailer body has a continually rounded bottom and sides and an open top.

Claims (14)

1. A modular trailer system comprising:

a plurality of curved panels, where each panel is elongate and has a first side with an angled projection and an opposing second side with an angled slot such that the angled projection of one panel is capable of fitting into the angled slot of another panel, allowing the panels to join together to form a continuously curved surface, where the plurality of curved panels form a trailer body with an open top, where the open top is narrower than a widest point of the trailer body due to the curvature of the continuously curved surface.

2. The modular trailer system of claim 1 where the plurality of curved panels are made of extruded aluminum.

3. A modular trailer system comprising:

a plurality of curved panels, where each panel is elongate and has a first side with an angled projection and an opposing second side with an angled slot such that the angled projection of one panel is capable of fitting into the angled slot of another panel, allowing the panels to join together to form a continuously curved surface;

a first top rail with an angled slot capable of receiving the angled projection of one of the plurality of curved panels; and

a second top rail with an angled projection capable of fitting into the angled slot of one of the plurality of curved panels.

4. The modular trailer system of claim 3 where the plurality of curved panels, first top rail, and second top rail are assembled together to form an elongate trailer body with a partially circular cross section, such that the trailer body has a continually rounded bottom and sides and an open top.

5. The modular trailer system of claim 4 where the plurality of curved panels, first top rail, and second top rail are joined via a weld on each joint, located on an exterior of the trailer body.

6. The modular trailer system of claim 5 where the joints are not welded on an interior of the trailer body.

7. The modular trailer system of claim 4 where the plurality of curved panels, first top rail, and second top rail are joined via adhesive in each joint.

8. The modular trailer system of claim 4 further comprising a liner.

9. The modular trailer system of claim 8 where the liner is made of steel.

10. The modular trailer system of claim 8 where each of the top rails comprises an inwardly projecting lip and where the liner is located within an interior of the trailer body and below the lips of the top rails.
