Abstract
A motorized chain roller includes a frame, a roller chain assembly movably disposed within the frame, a first sprocket that engages the roller chain assembly to apply a transmission force to the roller chain assembly, at least one motor coupled to the frame and configured to transmit a rotational force to the first sprocket, and a load-bearing member coupled to and located within the frame. The roller chain assembly includes a plurality of interconnected cylindrical rolls arranged in a continuous series. Each of the cylindrical rolls has an axis or rotation. The roller chain assembly engages the load-bearing member to cause movement between the roller chain assembly and the load-bearing member perpendicular to the axes of rotation.
