Features and benefits

Promotes increased productivity

Since the feeder breaker is located closer to the working face, haulage distances and travel times are reduced, resulting in increased production and efficiency of the remaining section equipment.

Easier section moves

Equipped with a powerful crawler drive system for quick, efficient belt moves. Plus, the feeder breaker can be connected to the conveyor belt to move them both simultaneously, saving time.

Splined breaker shafts

Splined connection versus a compression connection can reduce assembly and disassembly time by more than 50%, reducing downtime for replacement and service. Splined connection is also 25% stronger than previous connections.* *based on internal testing
