Abstract
Apparatus, and a related method, for controlling a moving floor having multiple sliding slats, to produce a practically continuous load-moving force on a load carried on the apparatus. The slats are reciprocated back and forth by hydraulic cylinders, each of which controls a group of slats that are moved together. At any given time, a majority of slats are moving together in the desired direction, and carry a load in this direction at a nearly uniform velocity. The remainder of the slats are moved in a reverse direction, but at a speed that is a multiple of the forward speed of the majority of the slats. Each group of slats is moved through a forward stroke at a relatively low speed; then through a backward stroke at a higher speed.
