RINGSPANN* • High Speed Backstops are located on the 2nd or 1st gearbox reduction shaft and prevent reverse motion of conveyor belts or bucket elevators. • They are equipped with sprag lift-off X which ensures a wear free freewheeling operation when the backstop is rotating at high speeds with the gearbox shaft. In this state of operation, the backstop works wear-free, i.e. with unlimited service life. • High Speed Backstops with Torque Limiting are used in belt conveyors with multiple drives and prevent reverse motion of conveyor belts. • They solve the problem of uneven load distribution in...
