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.
