ABSTRACT:
An overhead support system. An array of spoked rimless wheels are located over a space and supports at least one overhead cart from which a load is supported with a tension element. The load can be moved horizontally in the space by applying a horizontal force to the load causing the cart to move over the array of spoked rimless wheels carrying the load in the horizontal direction. The spoked rimless wheels rotate permitting the tension element to pass horizontally through the array of spoked rimless wheels. In preferred embodiments the spoked rimless wheel has the general shape of a star or a daisy and is referred to as a star wheel or a daisy wheel and the cart has a circular bottom surface. In preferred embodiments casters are mounted on top of the star wheels or daisy wheels to permit easy horizontal movement of the cart over the wheels. In other preferred embodiments the daisy wheels are flat on top and casters are mounted on the circular bottom of the cart.
