Atlas Copco goes compact with new breaker

Replacing the MB 1700 hydraulic breaker, Atlas Copco says its new MB 1650 is lighter and more compact yet gives the same high performance as its predecessor. The new design offers higher reliability, lower repair costs and easier accessibility for maintenance. Weighing in at 1,650kg, the MB 1650 is suitable for carriers in the weight class 19-32tonnes.

Replacing the MB 1700 hydraulic breaker, Atlas Copco says its new MB 1650 is lighter and more compact yet gives the same high performance as its predecessor. The new design offers higher reliability, lower repair costs and easier accessibility for maintenance.


Weighing in at 1,650kg, the 283 MB 1650 is suitable for carriers in the weight class 19-32tonnes. The company says that a redesigned service window offers greater accessibility and makes the attachment more maintenance friendly. Because there is no high-pressure accumulator, the MB 1650´s maintenance and repair costs are lower.

Breaker performance is optimised by AutoControl. An automatic piston stroke length switching system adjusts the output balance between impact energy and rate during operation.

161 Atlas Copco´s EnergyRecovery feature automatically uses piston recoil energy to increase performance without additional hydraulic input and also 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 also equipped with ContiLube II, a self-bleeding automatic lubrication device for optimised grease consumption and continuous lubrication.

Noise and vibration levels on the MB 1650 are minimised by the VibroSilenced Plus system. It uses non-metallic suspension arrangements to isolate the percussion mechanism from the breaker box and sealing all openings for lower noise and vibration levels.

The company says that an optional patented dust sealing system called DustProtector II will extend the service life of components and reduce grease consumption. The built-in check valve reduces dust intake into the tool guiding area and the percussion chamber.
