Abstract

A trailer body includes a rigid aluminum frame, the frame comprising: a load floor and underbody comprising structural extrusions oriented longitudinally; an arm structure for connecting to a hitch; subassemblies comprising aluminum extrusions formed into frames defining the body walls; and, optionally, at least one subassembly comprising aluminum extrusions formed into a frame defining the body roof, and wherein the load floor, wall subassemblies, and optional roof subassembly are fastened together to form a rigid final assembly. Roll formed steel tubular members may be substituted for the aluminum extrusions. The invention may further be adapted to make modular trailers that can be customized by choosing among different wall and roof modules. Related assembly methods are also disclosed.

Dependent claims

A trailer chassis comprising a rigid aluminum structure, the structure frame comprising:

a load floor and underbody subassembly comprising aluminum structural extrusions oriented longitudinally and welded together along their length to form a rigid platform, wherein the load floor and underbody subassembly comprises two structural extrusions having a deeper profile than the other extrusions forming the load floor, thereby forming structural beams to provide longitudinal stiffness;
three subassemblies comprising aluminum extrusions formed into frames defining body front and side walls;
an arm structure extending longitudinally from one end of the underbody subassembly to engage a hitch for pulling the trailer behind a powered tow vehicle;
and,
wherein the load floor, wall subassemblies, and arm structure are attached to one another to form a rigid body assembly.
