Komatsu Australia has released a low-emission version of its BR380JG-1 crusher, the new BR380JG-1EO, featuring its ecot3 low-emission system, beefed up safety systems and improved hydraulics.
Based around a 42x22 inch jaw crusher, the BR380JG-1EO has an operating weight of 34 tonnes, a throughput range of 50–240t per hour and is powered by a Tier 3-compliant Komatsu SAA6D107E-1 diesel rated at 140kW. A newly designed vibrating grizzly feeder moves material to be crushed in an elliptical pattern, so that the material is separated more effectively, and feeds into the jaw more evenly.
Komatsu said it also featured a unique hydraulic crusher protection system. In the event of the jaw being jammed, the KCJ4222 jaw system is protected by allowing itself to fully open the discharge port, making it easy to remove clogged material from the crusher.
Business manager of construction products Angus Fotheringham said a key contributor to increased productivity and operator safety was the addition of a fully remote system that allowed the new crusher to be fully controlled from an excavator or other external position.
"Komatsu has added significantly more functions to the remote, giving the excavator operator the ability to completely control the sequential start-stop process with the touch of a single button," he said.
