Backstop controls back running of inclined conveyors

The backstop is often specified on multi-drive systems such as large inclined conveyors where two or more backstops share the reverse load. The torque limiting function is performed through a multi-disc brake working in oil. This solution not only provides for a high torque density of the complete unit but also ensures that the set slip

Backstop funcion of gearbox reducersGeared Motor speed

The backstop functions by using centrifugal lift-off sprags. Once the lift-off speed is reached the sprags lift off from the contact surface of the outer ring completely. The backstop is lubricated with the gear unit oil. Direction of Rotation. FLK Drive installs backstops according

Proof Test Interval for Conveyor Holdbacks/backstops

Nov 12 2019 · Hi all I m based in Queensland Australia. Australian standards requires the designer to specify a proof test interval for conveyor backstops ( mandatory). Just wondering if any one can share the procedure and frequency of this test The standards also recommend monitoring wear and effective operation of holdbacks. However I have not come across any proven methods for achieving this.
