The Keith Walking Floor system is an unloading system. The hydraulically driven drive unit is installed in a trailer and attached to a series of floor slats that “walk” material out the rear of the trailer. Trailers unload horizontally without needing to raise the trailer and eliminating the need for a tipping platform.
Walking Floor systems unload nearly any bulk material, including waste, agricultural commodities, mulch, gravel, etc.
Since 1973, Keith Manufacturing Co. has produced the Walking Floor brand of moving floor unloading systems at its location in Madras, Ore. Systems are used in a wide variety of industries throughout the world to handle bulk materials. Keith Manufacturing Co. encompasses five international locations and has a global network of trailer manufacturers and dealers to service its customers.
Vertical integration allows the company to maintain superior quality control measures and enables the company to manufacture a diverse product line. At the company’s Madras facility, employees design, machine, fabricate and assemble nearly 100% of the components used in Keith Walking Floor systems.
How the Walking Floor unloader is made is fascinating and provides insight into the quality and workmanship that goes into this system. Work Truck toured their facility to share just how these unique products are made.
