Backstops for Belt Conveyors and Bucket Elevators
High Speed Backstops
- 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.
- Maintenance free
- Cost effective
High Speed Backstops with Torque Limiting
- 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 multiple drives.
- They are equipped with spraglift-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.
- Maintenance free
- The integrated torque limiters protect the gearboxes and backstops from overload by dynamic peak torques.
- Smaller gearboxes can be used without negatively effecting the safety.
- Available with or without controllable release function
- Cost effective
Low Speed Backstops
- Low Speed Backstops are located on pulley or head shafts of gearboxes and prevent reverse motion of conveyor belts or bucket elevators.
- Taconite seals protect the backstop from contamination with dust or dirt.
- Low Speed Backstops allow the removal of the drive unit when the conveyor belt is loaded.
