Less weight, same performance

By Steve Ducker12 April 2017

Germany-based manufacturer Atlas Copco says one of its ongoing goals is to help customers reduce operating costs and believes its new MB 1650 hydraulic breaker is a typical example.

Replacing the MB 1700, the MB 1650 is lighter and more compact yet gives the same performance as its predecessor.

The company also says the new design offers higher reliability, lower repair costs and easier accessibility for maintenance.

Weighing 1,650 kg (3,637 lb), the product breaker is suitable for carriers between 19 and 32 t.

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

In addition, Atlas Copco┬┤s EnergyRecovery feature automatically uses the piston recoil energy to increase the performance, without additional hydraulic input, and to lower 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.

Noise and vibration levels are said to be minimised by the VibroSilenced Plus system, using non-metallic suspension arrangements to isolate the percussion mechanism from the breaker box and sealing all openings for lower noise and vibration levels.
