A single conveyor can run at close to reliability, but as the number of conveyor increases, the reliability of the conveyor belt system is mostly depend upon its control system. The control system has sensing device like zero speed sensing, receiving conveyor position sensing.
8. Automated hold back brakes: A sudden stoppage of a loaded inclined belt conveyor may cause slipping back of the loaded belt. This will happen if longitudinal component of load weight which is larger than the forces of frictional resistance to belt motion.
Inclined conveyors require an antirunback 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 startup where the loaded belt sags between idlers.

Conveyor Backstop Inventory. At West River Conveyors, we offer a variety of conveyor belt backstops to our customers. These backstops can protect your machinery from highspeed reversals which can significantly damage your belts and motors.
Working Principle. Belt Conveyor is a machine taking the friction as the driving force to transport materials in continuous way. The equipment consists of frame, conveyor belt, support, roller, tensioning device, driving device etc..
Operating Principle Of Industrial Conveyor Belt System. Before starting conveyor belt system it is necessary to start first receiving conveyor and then start feeding conveyor operating logic is from down stream to upstream. For stopping of conveyor system the operation will be opposite from upstream to down stream.
Conveyor Belt common problem trouble shooting guide E. Bolt heads from pulley lagging, or from slider bed material hold down on bare backs, are sticking up and catching the belt. cleaning devices. D. The conveyor frame is not square or the system is not properly supported.

Conveyor Belt Safety Procedure TPSMS/GSP/CONV/002 REV 01 Date of Issue: Start/Stop of belt 1. If a conveyor belt needs stopping, it should never be stopped in load condition, except emergency. 2. If the high speed coupling in the drive is a fluid coupling, the number of start/stop of the conveyor belt should not be more than
A typical pawl and ratchet holdback device, showing the position of the pawl moving over the ratchet teeth when the belt is running in the direction of the arrow. Fig. 12 shows the pawl engaged in the teeth of the ratchet wheel. This will be the position if the belt runs in reverse as indicated by the arrow.

Hold back will not be in operation for most of the time, hold back only comes in to the picture if any mechanical failure or electric failure occurs and conveyor belt tends to move in reverse direction. Hold back will restrict the reverse movement of conveyors. Hold
Superior Industries P/7 Deflects fugitive material from trapping between wings for extended belt and pulley life. n Continuous contact between pulley and belting reduces noise, vibration and extends bearing life. n Friendlier and less abusive than traditional wings on conveyor belt splicing and clips. n Time tested, the original vshaped pulley debuted way back in 2007.
