The risk of uncontrolled reversing of the conveyor is eliminated in the event of a motor or gearbox breakdown by installing an S-A Holdback. For maximum reliability, the Holdback is fitted directly on to the shaft of the drive pulley.

Designed for economic and dependable operation, the S-A Holdback gives effective protection against injuries to persons, flooded loading stations, and ruined equipment as a result of belt reversal or caused by belt reversal.

Standard Roller Type
  • Simple open design
  • Low-cost, dependable protection
  • Engages instantly without shock
  • Proven roller-wedge operation

Not to be used on equipment that moves people or in indexing applications.
