Wabash End-Dump Trailer (aggregate, construction)
Wabash National · Dump Trailer · 36 ft · 65,000 lb GVWR
What this trailer does
End-dump trailers are hydraulically-actuated tipping trailers for hauling bulk aggregate (sand, gravel, crushed rock), asphalt, and construction debris. Wabash builds end-dumps alongside the major dump trailer specialists (Travis, East Manufacturing, Trail-Eze, Reliance). Length varies: 23-40 feet depending on weight regulations in operating states. Hydraulic cylinders raise the trailer body at the front, allowing material to slide out the rear gate. Frame-style and frameless designs available — frameless is lighter (more payload) but more expensive.

Design and engineering
Aluminum or steel body (aluminum more common for payload). 23-40 foot length. Hydraulic dump cylinder powered by truck PTO (power take-off). Rear tailgate (manual or hydraulic) seals during transit, opens for unloading. Triple or quad axle on heavier specs to meet 65,000-95,000 lb GVWR (varies by state).
Generations and major changes
- Wabash End-Dump (2000–present)Long production run. Frameless variants added 2010+.
Reliability and longevity
Built for severe-duty. Hydraulic cylinder + lift gear are the main maintenance items. Aluminum bodies last 10-15 years before metal fatigue from repeated dumping cycles.
Common problems
Hydraulic cylinder leaks. Hinge wear from repeated dump cycles. Tailgate latch wear. Frame stress cracks (steel) or weld fatigue (aluminum).
Maintenance schedule
Annual DOT inspection. Hydraulic system service every 1,500-2,500 dump cycles. Brake service every 50K. Frame inspection at every PM.
