East Manufacturing

Randolph, Ohio-based East Manufacturing’s new Genesis aluminum dump and transfer trailers will cost less to operate, last longer, look better, and bring more at resale according to President David J. Tate, who introduced them at the Mid-America Trucking Show.

The smooth sidewalls of Genesis trailers can be left polished as they come from the East factory or used as the base for company names, logos, and attention-getting graphics.

The sidewalls are built of unique double-wall aluminum extrusions robotically welded together in a patented process. Each two-inch thick extrusion runs the full height of the sidewall, and has two internal ribs connecting the inner and outer skins. Computer analysis, laboratory testing and extensive field testing show this sidewall to have superior strength, with better resistance against bowing than the traditional sheet-and-post construction.

The double-wall configuration also prevents any dings on the interior from showing on the exterior, an attractive plus for maintaining trailer appearance over the years, enhancing resale value.

The Genesis sidewalls provide superior wear resistance on the interior. With vertical ribs every three inches, the Genesis sidewall has eight times the support provided by external posts positioned every 25 inches, the company says. This means minimal deformation between the ribs. When wear is a major concern, Genesis trailers can be specified with thicker inner skins in the rear four feet where most wear occurs.

The trailers also employ an interlocking system that makes the wall-floor connection far stronger. Cross-members and floor plates interlock with the rub rail, which in turn forms a pocket to accept the sidewalls. Voids in the sidewalls can be filled with insulation for trailers that haul hot asphalt.
