ALUMINUM FLATBED WITH UNIQUE FRONT CONNECTION

摘要

A drop deck trailer frame includes a front section having a first upper surface, a rear section having a second upper surface lower than the first upper surfac e, and an improved connection between the front and rear sections which tends to reduc e cracking which commonly occurs in drop deck trailer frames due to the stress es in the region of the connection. The connection preferably includes a semicircular weld. In addition, heat treated bent flanges are typically used to provide additional strength. Fasteners such as bolts are also typically used to connect various flanges.< /SDOAB>
