发明名称 Limited movement roller system
摘要 A limited movement roller device and related method for moving a load includes a frame with a load bearing surface. A plurality of rollers are moveable through the frame and connected with respect to each other. A stop block is positioned within a void between two rollers of the plurality of rollers so as to obstruct movement of the plurality of rollers through the frame. Accordingly, a load may be maneuvered by reaching a braking point of the roller device and then rotating the load and the roller device 180° relative to each other prior to moving the load again to the braking point. This process may then be repeated to move the load without risk of losing control of the load, such as down an incline.
