High angle conveyors climb to the top
Since the face conveyor is such a critical link within a longwall mining system, operators can use the information to improve the efficiency of their longwall operation. A conveyor chain is of very high tensile strength (resulting in high breaking load) and its actual working load is often a substantial portion of its breaking load.
