Atlas Copco Construction Tools LLC offers the MB 1000, a hydraulic breaker suitable for the popular 12 to 20 metric ton class of excavators. The unit features Krupp percussion technology and is primarily designed for demolition, tunnel construction, secondary breaking, trenching and foundation work.

The breaker’s design combines extreme reliability with high single-blow energy and efficient impact frequency. With a service weight of 2,200 pounds, it accepts a hydraulic flow of up to 34 gallons per minute at 2,610 psi of pressure, delivering a maximum of 720 blows per minute.

The MB 1000 includes features such as AutoControl and StartSelect, which are both part of Krupp percussion technology. AutoControl is a monitoring system that 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 on tension bolts and retainer bars.

To further maximize efficiency, the MB 1000 features the StartSelect system, allowing 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. AutoStop 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 features of Krupp percussion technology that come standard on the MB 1000. 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.

For added maintenance convenience, the MB 1000 can be equipped with an optional DustProtector, which prevents dust penetration by utilizing a reusable sleeve that contacts the working tool at the base of the breaker. This protects the inner mechanism from the damaging effects of dust.
