KEITH WALKING FLOOR System: How It Works - Video
The WALKING FLOOR® system is made of a series of floor slats, which are powered by a hydraulic drive, usually located underneath. As the floor moves through its four-phase cycle, every third slat moves together. During the final phase, all slats move in unison conveying the material. The friction of the load on the two sets of slats that remain in place keeps the load from moving while the single set of slats moves.
