Abstract:
1. A method for constructing a platform trailer, said method comprising: constructing a platform subassembly comprising plurality of extruded aluminum panels that each extend from a left lateral end to a right lateral end, each of said panels comprising an upper wall, a lower wall spaced-apart from said upper wall, and first and second spaced-apart end walls that are connected to and extend between the upper and lower walls, wherein said extruded aluminum panels are abutted in series with the first end wall of one panel abutted with the second end wall of an adjacent abutted panel to define a seam between each pair of adjacent abutted panels, such that the respective upper walls of adjacent abutted panels define a cargo supporting surface of said platform subassembly and said respective lower walls of said adjacent abutted panels define a lower surface of said platform subassembly, said step of constructing a platform subassembly comprising connecting each pair of adjacent abutted panels to each other by welding said pair of adjacent abutted panels to each other at said seam; applying force to said platform subassembly to deform said platform subassembly into an arched shape and contacting respective flanges of first and second parallel spaced apart arched beams to said lower surface of said platform subassembly such that said arched shape of said platform subassembly conforms to said arched first and second beams, wherein each of said panels of said platform subassembly is oriented transversely relative to said first and second beams such that each of said panels contacts the respective flanges of both said first and second beams; and, welding said respective flanges of said first and second parallel, spaced apart arched beams to said lower surface of said platform subassembly while said platform subassembly is held in its arched shape in contact with said respective beam flanges.
