3.3 Sheepsfoot Rollers Sheepsfoot rollers have largely been replaced by its more efficient variant, the segmented pad roller, and will only rarely be encountered. The sheepsfoot roller compacts from the bottom of the lift upwards to the top of the lift. Therefore, the loose lift thickness is limited to 15% longer than the length of the feet.
