The new MB 750 hydraulic breaker from Atlas Copco: reduced lifecycle cost and up to 54 % more percussive performance

Updated Sep 20, 2010

More percussive power does not mean that the breaker adds extra weight to the carrier. Thus, the MB 750 allows the use of a smaller breaker and carrier for the same kind of job. In fact, this helps to bring the investment cost to a lower level and furthermore to reduce the fuel consumption significantly. Together with increased productivity these are the main contributions to reduced lifecycle cost. 


The high operational efficiency of the MB 750 is devoted to a combination of oil and gas power and energy recovery by utilizing the recoil effect in the best possible way. This boosts the output power of the breaker without increasing the hydraulic input power of the carrier, which results in less fuel consumption during operation.


Atlas Copco breakers contain a highly effective noise and vibration damping. The new MB 750 is no exception with its guaranteed sound power level of 118 dB (A), measured according Directive 2000/14/EC. Atlas Copco’s VibroSilenced system isolates the percussion mechanism acoustically from the external guide system. Moreover, the VibroSilenced system helps to prevent damaging vibrations that could be detrimental to both the carrier and the operator.


A new feature on the MB 750 is the double retainer bar system, which maximizes the service of the tool and retainer system. Extra long retainer bars provide a maximum contact surface to the tool and the lower hammer, and they can be used on both sides for extended service life. Double retainer bars offer higher wear resistance than a retainer pin and are a reliable and proven locking system for the working tool.


The MB 750 is optionally available with the patented DustProtectorTM II, a two-stage sealing system with coarse and fine wipers that reduce the penetration of abrasive dust into the lower hammer part. DustProtectorTM II also keeps the lubricant around the wear bushing for a longer period of time, lowering grease consumption. The system reduces wear on the bushings and the hammer and protects against damage.


The MB 750 is ideal for secondary breaking, demolition, excavation and trenching, tunneling, and special applications such as underwater or any job that calls for a hydraulic breaker with a powerful, efficient and reliable design.
