Enhancing Overland Conveyor Safety and Productivity

Downhill Overland Conveyors Generally, belt conveyors only require braking when it takes too long for the system to come to rest (i.e., during a power failure or to prevent "roll-back" of the load when the conveyor is inclined/ declined). In the case of an inclined conveyor, it's normal to use a backstop.
