For many operations, the key to successful fleet management is versatility. A trailer fleet that can handle many different materials, while still hauling a hefty payload, can be an invaluable asset. KEITH Walking Floor Unloading System technology installed in a trailer provides haulers with the ability to move many different materials, as well as unload in numerous environments. The foundation of the moving floor system is a series of hydraulically actuated floor slats and a drive unit. The drive unit powers the slats through a four-phase cycle to convey the material. Moving floor systems provide flexibility to unload at a variety of sites during backhauling. Unlike dump trucks, which are limited by vertical height restrictions, moving floor systems can be used to unload material near or inside buildings, as well as in residential areas where trees and overhead power lines pose hazards. Several innovative features set the Walking Floor system apart, including a patented double-rod arrangement of the Running Floor II hydraulic drive unit. This divides the unloading force between both ends of the drive frame, distributing the force and allowing for shorter unloading times. A Running Floor II drive unit, equipped with the proper wet kit, is capable of unloading a full-sized trailer in three to five minutes. Trailers outfitted with moving floor unloaders are ideal for the transport of mulch and other organic materials, hauling municipal waste, and delivering recyclables for processing. Automating the materials handling process at waste and recycling locations can increase productivity and improve throughput, maximizing available resources.
