Since the roller only rotates within the range of the lower surface of the roller, it does not protrude to the front or rear of the cart unlike conventional roller devices, which narrows the work space. In addition, there is no need to correct the misalignment of the rollers that tends to occur as with conventional linear roller devices, and in the past, the moving distance of the trolley was limited by the number of rollers, but with the Endless Roller 4, the wheels can move easily. It has the advantage of not being subject to restrictions on movement distance, as in the case of
