Product Overview

Leading Edge Technocrat offers robust external holdbacks designed to prevent reverse rotation of inclined conveyors, bucket elevators and other material-handling drives. Mounted externally on an extended shaft, the holdback provides automatic backstop action whenever the drive attempts to rotate in the reverse direction.

The compact housing, torque arm support and precision freewheel mechanism allow smooth overrunning during normal operation and positive locking during rollback. Its accessible external mounting simplifies inspection and maintenance while helping protect gearboxes, motors, shafts and conveyed material during power failure or emergency shutdown.
