SafeSet Application: Armored Face Conveyor Reduce the risk of a chain break and increase productivity. Protecting an AFC from conveyor chain breakage can prevent extensive downtime and potential damage. The AFC can come to a sudden stop when it encounters a geological rock fault, hard material, or gaps. The inertia of the driveline and motor continue to deliver torque, which can cause severe damage or overheating. Joy Mining Machinery has installed SafeSet torque limiting couplings to protect against the chain breaking during pro- duction. A chain break can create significant downtime as the conveyor needs to be cleared of built up rock or coal. Customer benefit • Protection against chain breaks and driveline failure • Minimized extensive machine downtime • Quick resetting for maximum uptime

SafeSet Application: Armored Face Conveyor
Reduce the risk of a chain break and increase productivity.Protecting an AFC from conveyor chain breakage can prevent extensive downtime and potential damage.
The AFC can come to a sudden stop when it encounters a geological rock fault, hard material, or gaps. The inertia of the driveline and motor continue to deliver torque, which can cause severe damage or overheating.
Joy Mining Machinery has installed SafeSet torque limiting couplings to protect against the chain breaking during pro-duction. A chain break can create significant downtime as the conveyor needs to be cleared of built up rock or coal.
Customer benefit• Protection against chain breaks and driveline failure• Minimized extensive machine downtime• Quick resetting for maximum uptime
Customer Joy Mining MachineryA global leader in the development, manufacture, distribution and service of underground mining machinery for the extraction of coal and other bedded materials. Joy manufactures long-wall shearers, roof supports, face conveyors, stageloaders, continuous miners, batch haulage vehicles, continuous haulage systems and bolting products for use in longwall and room and pillar mining operations.
SolutionSafeSet torque limiting couplings SR-PG 440, 550 and 660 protect the chain by slipping and limiting the torque peaks. The coupling is designed to either release at longer durations, or not release at all, to prevent the drive from disengaging completely.
