PRESS RELEASE ACE’s New Ultra-High-Tensile-Strength Steel Bottom Dump

At 9,680 lbs., new super-steel belly dump is 30 percent lighter, handles better, discharges cleaner and pays for itself with extra load capacity

American Carrier Equipment (ACE) a 79-year-old California construction trailer manufacturer recently announced that it is now delivering a new, ultra-high-tensile-strength steel bottom dump trailer in the western United States.

The all-steel, tandem-axle, semi-bottom-dump trailer is the culmination of a two-year research, development and field-testing program aimed at producing a tough, lightweight breed of trailer for severe-duty applications. The new trailer is 30% lighter, has 300% greater structural integrity and accommodates 12.5% greater load capacity than similar units, according to the Fresno-based company.

Careful attention has also been paid to the new trailer’s off-road performance and handling characteristics. ACE employed advanced design techniques, including finite element analysis (FEA) testing, allowing its engineers to simulate a wide variety of dynamic stresses, from extreme heavy-haul loads to punishing off-road conditions and accelerated aging. The company says it was the first to taper its steel trailer’s front and rear structural members, because FEA showed that tapering alleviates stress points throughout the trailer, creating a stronger framework and a lighter vehicle in the process.

Towing properties have also been enhanced through the addition of a unique, fully oscillating kingpin. The ACE bottom dump kingpin functions as a solid, finished bearing, helping to absorb and disperse the lateral stresses exerted on the trailer through pull and brake torque. Working as a technically advanced hauling system, the design of the new bottom dump trailer makes it easier to load, tow and discharge on harsh and severely challenging terrains.

The new ACE bottom dump trailer has superior discharge characteristics, according to the company. The interior bed slope has been engineered to promote optimum load release flow when the gate is opened. The design promotes complete emptying and reduces the potential for load material, such as asphalt, to “bridge” or form into non-flowing masses that remain in the trailer bed.
