East Manufacturing launched its new Horizon round bottom trailer, saying it was designed with the needs of aggregate, sand, and gravel haulers as well as haulers of agriculture loads in mind.
The announcement came during the annual meeting of the American Trucking Associations' Technology & Maintenance Council in Orlando, Florida, on March 6.
The Horizon maximizes payload by incorporating lighter-weight components while still delivering strength and durability, according to East. The new round-bottom design provides a lower center of gravity for greater dump stability and better cornering.
The round-bottom shape also allows the trailer to empty cleaner and faster than traditional square-bottom trailers. In addition, Horizon offers a greater payload capacity when compared to a traditional half-round trailer.
Horizon’s low profile “provides a sleek, good-looking” and a more stable dumping platform. Like all East frameless dump trailers, the Horizon round bottom uses only premium aluminum alloys for flooring and sidewall material for long life and durability. Premium-grade aluminum floors are built with up to 33% more yield strength than industry standards.
Its base weight is 9,860 pounds without options, a liner, or tarp system, which is lighter weight when compared to the East Hybrid dump trailer. It’s 102 inches wide and is available in lengths up to 40-feet long. For weight-conscience operations, its sidewall heights include 52-, 56- or 60-inch for 43.4-, 46.8- and 51-cubic-yard capacity, respectively.
East also stated that the aerodynamically styled bulkhead aids air flow to help improve fuel efficiency while its large radius bracing helps to distribute loads. The external doghouse connects to an under support system of U-shaped channels fastened and gusseted at critical torsion points, in addition, stress is transmitted to neutral areas of the sidewalls, virtually eliminating stress cracks, and the externally mounted hoist is easier to maintain.
Horizon’s lightweight/long-life upper coupler has a replaceable stainless steel saddle receiver assembly bolted into a lightweight aluminum sub-structure for reduced tare weight and maximum durability. Also, the aerodynamically designed fenders protect the trailer from road debris and provide “a nicely finished look.”
