Atlas Copco adds new MB 1650 hydraulic breakerPublished 16/5 at 12:55
Atlas Copco has replaced the MB 1700 hydraulic breaker with the new MB 1650, which weighing 1.65t is suitable for 19t to 32t class carriers and a broad spectrum of mining and quarrying, demolition and construction applications.
A redesigned service window offers greater accessibility and makes the attachment more maintenance friendly. With no high-pressure accumulator the MB 1650´s maintenance and repair costs are lower.
Breaker performance is optimized by AutoControl, an automatic piston stroke length switching system, which adjusts the output balance between impact energy and rate during operation.
Atlas Copco´s EnergyRecovery feature automatically utilizes the piston recoil energy to increase the performance, without additional hydraulic input, and lowers vibrations.
The integrated StartSelect valve enables the operator to adjust the hydraulic breaker start-up behaviour according to the operating condition in a few simple steps.
The MB 1650 is equipped with ContiLube II, a self-bleeding automatic lubrication device optimizing grease consumption and continuous lubrication.
Noise and vibration levels on the MB 1650 are minimized by the VibroSilenced Plus system. This uses non-metallic suspension arrangements to isolate the percussion mechanism from the breaker box and sealing all openings for lower noise and vibration levels.
An optional, patented dust sealing system called DustProtector II will extend the service life of the components and reduce grease consumption. The built-in check valve reduces dust intake into the tool guiding area and the percussion chamber.
