Seems like many municipalities and contract haulers prefer an ejector style trailer in lieu of a live floor trailer. As a result, Warren builds both styles of transfer trailers. Spec your ejector trailer with a closed or open top trailer design. Numerous tarp systems and other roof options are available for open top ejector trailers. We manufacture these trailers in aluminum, mild steel, or AR-450 high tensile strength steel. We highly recommend AR-450 high tensile steel trailers for severe environments. Warren ejector trailers come standard with a 16″ tall watertight seal. And, we also can offer full watertight trailers if this is a requirement for your application. Usually, our push-out trailer tailgates are custom designed to meet your landfill equipment or job needs. Ejector trailers do require a large quantity of oil in order to operate. Therefore, we can add the hydraulic tank on to the trailer design or we can supply and/or install a complete wet line kit on your tractor to operate the trailer.
