Atlas Copco Construction Tools Offers MB 1700 Hydraulic Breaker Attachment

Updated Sep 22, 2010

WESTFIELD, Mass. â€“ Featuring industry leading Krupp percussion technology, the MB 1700 hydraulic breaker from Atlas Copco Construction Tools LLC is ideal for rock mining, demolition, secondary breaking, tunnel construction, trenching and foundation work.  


The design of the MB 1700 combines extreme reliability with high single blow energy and an impressive impact frequency of up to 600 blows per minute. At a service weight of 3,750 pounds, the MB 1700 is suitable for excavators in the 18 to 34 metric ton weight class and has a maximum hydraulic input flow of 42 gallons per minute at a maximum operating pressure of 2,610 psi.  


The MB 1700 includes the AutoControl monitoring system, which allows the breaker to adapt its frequency and power output to match operating conditions. It begins by firing the first stroke at half power to create a pilot notch that will center the working tool and prevent unnecessary tool slippage. It then adjusts the power output to match the density of the specified material to be broken. This reduces excess shock on both the breaker and carrier and lengthens the service life of tension bolts and retainer bars.  


To further maximize efficiency, the MB 1700 features the StartSelect system, which allows start-up and shut-off to be adjusted to fit job-site conditions. In AutoStop mode, the breaker will not fire until the operator applies down pressure on the demolition tool via the carrier. AutoStop eliminates damaging blank firing by circulating the hydraulic oil internally under low pressure when down pressure is not applied to the tool. This feature is ideal for safely circulating and warming the hydraulic system before breaking in cold climates.  


In AutoStart mode, the StartSelect system works hand-in-hand with AutoControl. The breaker begins operating as soon as the working tool comes in contact with the material regardless of down pressure, but power is limited to 50 percent until the demolition tool can be fully seated in the breaker. This assures that the breaker is properly positioned to accept full single blow energy safely, without a damaging blank fire. AutoStart mode makes the breaker more versatile and is ideal for demolition applications.  


The VibroSilenced damping system and ContiLube II are two other exclusive features of Krupp percussion technology that come standard on the MB 1700. The VibroSilenced damping system helps to alleviate excess noise and vibration. ContiLube II is an automatic lubrication system mounted directly on the breaker. Featuring a compact, self-priming pump, ContiLube II eliminates the need to manually grease the breaker before each use. Lubricant levels are easily observed from the driver’s cab.  


An optional DustProtector can add convenience and ease to maintenance by preventing dust penetration. By utilizing a reusable sleeve that contacts the working tool at the base of the breaker, the DustProtector protects the inner mechanism from the damaging effects of dust.
