Below is a list of Ball Transfer Conveyors manufacturers from Hartland, Wisconsin. Ball transfer conveyors are a type of material handling system that facilitates omnidirectional manual transportation. They use a large number of fixed rolling balls to transport products instead of a conveyor belt or chain. These conveyors efficiently move boxes, packages, products, materials and parts that have flat bottoms and are heavy to lift. The ball sizes are usually comparable to pool balls and are made of either steel or nylon depending on the fragility of the products being moved.
