ABSTRACT:
The speed of a pallet as it descends down a pair of inclined rails in a flow rack is controlled by a series of speed-control wheels mounted on axles fastened to frame members located underneath the pallet. A tapered roller bearing is interposed between each axle and wheel to mount the wheel for combined rotary motion and axial motion. Brake pads are mounted on the frame member for engaging a braking surface on the wheel as it moves axially in response to the pallet load. The brake pads apply friction to the wheel for slowing the speed of the pallet. A bar is provided adjacent the lower end of each rail for engaging the speed control wheels on the pallets to increase the axial pressure thereon and to increase friction for arresting the pallets and separating the same.
