  • Patent number: 8647044
    Abstract: The light-weight live-floor module has a floor surface, parallel cables laid on the floor surface, a length of conveyor belt laid on the cables, a movable bulkhead and a winch system for moving the belt, the cables and the bulkhead back and forth in unison, such as a shuttle. The belt has just enough length to cover the return axis and the floor surface on which goods are transported, thereby reducing any unnecessary weight in the live floor structure. The cables and the belt are wrapped over different axes for eliminating relative movement between the cables and the belt. One axis is set higher than the floor surface for easily breaking static friction under the belt. In a method for breaking static friction between a conveyor belt and a floor surface, a first segment of the belt is jolted upwardly while tension is applied in the belt.
