Figure 1 – Safe Torque Off function [1] At the beginning of the stopping process (orange arrow and dotted line), the drive gate pulses are immediately shut off, removing torque from the motor (i.e., zero torque). The speed of the driven equipment will drop at a rate determined by the system friction and inertia until standstill is achieved.
Above 45-degrees an inclined screw conveyor is considered a vertical screw conveyor and must be designed in accordance with the KWS Engineering Guide for Vertical Screw Conveyors. As the degree of incline increases, conveying efficiency is reduced and horsepower requirements increase due to the effects of gravity and bulk material fall back.
Conveyor Belt Safety Procedure TPSMS/GSP/CONV/002 REV 01 Date of Issue: 30-06-2016 6. STEPS OF PROCEDURE: 6.1.

Inclined conveyors require an anti-runback device to prevent reverse movement of the belts. Such a device is referred to as a backstop, or holdback. Though backstops are most likely to be found on inclined conveyors, they are also employed on flat, overland conveyors to avoid the unusually severe shock loading on start-up where the loaded belt ...
