Trailer Unloaders

We Don’t Build Trailers, We Unload Them

Improving efficiency is the goal for every operation. Investing in the right trailer unloading system can ensure both profitability and productivity. The horizontal unloading action of a WALKING FLOOR® system eliminates many of the hazards of using dump or tipper trailers, which can overturn.

Unload safely inside buildings and tunnels, under utility lines, during windy conditions and on uneven or unstable ground.

KEITH® Sweep Systems

KEITH® Sweep Systems clean the floor of the trailer as it unloads, reducing payload cross contamination. The automated system eliminates the need for brooms or manual tarps so the operator never needs to enter the trailer, providing a safer working environment. Sweep systems are based on the floor profile and the material unloaded. For more information, visit the KEITH Sweep Systems page or download the brochure.
