BR580JG-1 mobile jaw crusher features Komatsu's patented HydrauMind fully hydraulic drive system that delivers the optimal amount of oil through load-sensing and pressure-compensated valves. According to Komatsu, this system senses overloads and automatically slows down the feeder. With an operating weight of 108,000 to 112,440 pounds, the machine is powered by a 345-horsepower Komatsu SAA6D125E-5 diesel. Newly designed vibrating grizzly feeder separates and evenly feeds material into the new KCJ4430 jaw, which has a load-presetting semiautomatic feeder system. Automatic discharge system can be reset with one-touch operation. Estimated list price: $776,000.
