MB Crusher Freză hidraulică R500

MB Crusher MB-R500 hydraulic drum cutter, new The smallest drum cutter in the MB Crusher range: at 300 kg it turns a mini excavator or a skid steer loader into a real milling machine. For any job that calls for efficient, precise milling of compact material — concrete, rock, asphalt, stone walls — in places a large machine cannot reach. Drive Twin Motor System MB states its cutters are the only ones on the market built directly with the Drive Twin Motor System: a twin direct-drive motor arrangement that splits force between the two drums according to what each one needs at that moment. When one drum meets harder material, Power Boost sends more power there instead of slowing the whole cutter down. Advantages Low vibration. Control devices reduce the vibration passed into the carrier machine’s arm: less wear on the excavator, and work becomes possible in city centres where vibration and noise have to be kept down. Reliability under heavy use. A device is available to reduce the excavator’s hydraulic oil temperature during long shifts. Longer service life. Anti-wear plates protect the cutter’s central body. Underwater work. The cutter is suitable for submerged operation. Drum change on site. The drums can be replaced at the work site in under an hour, safely, with no trip to a specialist workshop.
