Abstract:
A pair of elongate attachment members, or “Z-rails” for attaching an end of a trailer crossmember to a flanged beam each include a first end section, an L-shaped portion comprising a horizontal leg and a vertical leg extending from the first end section, and a second end section extending from the vertical leg. The horizontal leg has a bottom surface with a width equal to the distance between the web of the flanged beam and the end of the flange. The vertical leg has an outer surface with a width equal to the width of the end of the flange. The Z-rails are attached to opposite ends of the crossmember to form a subassembly. The subassembly is fixed to and between the flanged beams by welding the first end sections to the web of the corresponding beam, with the horizontal leg on the flange, without directly heating the flange, thereby not diminishing the toughness of the flange.
