Method of making a modular truck body
First Claim
1. A method for making a truck body disposed on a longitudinal axis thereof comprising the steps offabricating a unitary first module to have a generally L-shaped cross section defining a generally vertical first side section and a generally horizontal first bottom section,fabricating a unitary second module to have a generally L-shaped cross section defining a generally vertical second side section and a generally horizontal second bottom section having a lateral width substantially less than the lateral width of said first bottom section,disposing and aligning said first and second modules in side-by-side relationship to define a separation line between said first and second bottom sections extending the full length thereof and laterally disposed in substantial offset relationship relative to the longitudinal axis of the composite first and second modules forming said truck body,releasably attaching said first and second modules together at said separation line to form a pre-assembled and fully aligned truck body,securing a back-up plate to a free edge of said first bottom section, to overlie an edge of said second bottom section, after said attaching step,detaching and separating said first and second modules from each other at said separation line,shipping said separated first and second modules to a remote location,again disposing and aligning said first and second modules in side-by-side relationship at said separation line while simultaneously guiding such alignment by overlapping said separation line with said back-up plate,again releasably attaching said first and second modules together at said separation line, andfixedly securing said first and second modules together at said separation line to form a structurally integrated truck body, including the step of welding said back-up plate to said first and second modules adjacent to said separation line.

Abstract
A modular truck body comprises unitary first and second modules having bottom sections thereof secured together at a separation line which is substantially offset laterally from a longitudinal axis of the truck body. The width of the first module is thus substantially larger than the width of the second module. The modules are aligned and preassembled at a manufacturing plant by releasably securing them together at the separation line therebetween. The modules are then disassembled and shipped to a remote job site or the like for final reassembly and securance of the modules together.

1. A method for making a truck body disposed on a longitudinal axis thereof comprising the steps of
fabricating a unitary first module to have a generally L-shaped cross section defining a generally vertical first side section and a generally horizontal first bottom section, fabricating a unitary second module to have a generally L-shaped cross section defining a generally vertical second side section and a generally horizontal second bottom section having a lateral width substantially less than the lateral width of said first bottom section, disposing and aligning said first and second modules in side-by-side relationship to define a separation line between said first and second bottom sections extending the full length thereof and laterally disposed in substantial offset relationship relative to the longitudinal axis of the composite first and second modules forming said truck body, releasably attaching said first and second modules together at said separation line to form a pre-assembled and fully aligned truck body, securing a back-up plate to a free edge of said first bottom section, to overlie an edge of said second bottom section, after said attaching step, detaching and separating said first and second modules from each other at said separation line, shipping said separated first and second modules to a remote location, again disposing and aligning said first and second modules in side-by-side relationship at said separation line while simultaneously guiding such alignment by overlapping said separation line with said back-up plate, again releasably attaching said first and second modules together at said separation line, and fixedly securing said first and second modules together at said separation line to form a structurally integrated truck body, including the step of welding said back-up plate to said first and second modules adjacent to said separation line.
