Stieber Clutch torque limiting/load sharing backstops with release functionality allow the tension of a jammed mine conveyor belt to be carefully released using a simple hydraulic pump.
These releasable backstops are capable of performing as many reverse rotations as required (within the limits of energy dissipation) to completely unload a conveyor prior to performing maintenance work. This feature can significantly reduce downtime and ensure that any loss of productivity is kept to a minimum on large inclined conveyors. Model RDBR-E low-speed releasable backstops are externally mounted, self-contained on a shaft extension with a torque arm. Units are ideal for use on conveyors that require load sharing or a release function. Model RDBK high-speed releasable backstops are designed for multi-drive conveyor systems, where two or more backstops share the reverse load.
