The HB 3000 hydraulic breaker from Atlas Copco Construction Tools LLC features Krupp percussion technology and a service weight of more than 3 tons, making it ideal for demolition, tunneling, trenching, foundation work and secondary quarry breaking.

Accepting a maximum hydraulic flow of 71 gallons per minute at 2,610 psi of pressure, the HB 3000 delivers an impact rate of up to 540 bpm. This allows maximum productivity under some of the most extreme breaking conditions.

The HB 3000 comes standard with AutoControl, 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 HB 3000 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. AutoStop is also 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 into 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 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 ideal for demolition applications.

An energy recovery system that prevents damage from piston recoil on extremely hard materials is standard on the HB 3000. The system consists of a shuttle valve that detects piston rebound and a high-pressure accumulator that stores energy from piston recoil. The stored energy is used on the succeeding strokes, making them faster and harder. Recycling recoil energy increases efficiency and reduces pressure spikes transmitted back to the carrier.

To reduce excess vibration and noise, the HB 3000 comes equipped with the VibroSilenced damping system. Elastic elements between the percussion mechanism and the guide system provide full acoustic insulation, reducing noise by up to 18-dB(A) compared to similar systems.

For prolonged service life, the HB 3000 features DustProtector II and ContiLube II. The optional DustProtector II feature prevents dust penetration by utilizing a reusable sleeve that contacts the working tool at the base of the breaker to protect the inner mechanism from the damaging effects of dust. 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
