New Heavy Hydraulic Breakers with Optimized Power-to-Weight Ratio
In doing so, Atlas Copco sticks to the principle of developing and building attachments offering an improved power-to-weight ratio. The same performance can be achieved with a smaller attachment and carrier unit. Investment and maintenance costs are reduced. More power also means a higher strain against which the attachments are protected by proven and new product features. All three hydraulic breakers are equipped with the PowerAdapt system which shuts down the breaker in case the oil pressure is too high. With an improper carrier oil pressure setting, conventional pressure relief valves as the ones frequently used in hydraulic breakers continuously drain oil into the tank and therefore waste precious energy. This affects the efficiency and profitability of the equipment. The improved guide system of the hydraulic breakers provides a better stability and resistance. All proven features of Atlas Copco’s heavy hydraulic breaker line are also found in the three new models: the VibroSilenced System to protect operators against noise and vibrations, AutoControl to adapt the blow frequency and impact energy to the rock hardness as well as the integrated automatic lubrication system ContiLube™ II. With StartSelect the operator can influence the starting and shutdown behavior of the hydraulic breaker. And with the optional DustProtector the hydraulic breaker is protected against dust and rock particles penetrating the lower breaker part.

At bauma 2010, Atlas Copco introduced three new heavy hydraulic breaker models with PowerAdapt and optimized power-to-weight ratio. The HB 2000 with its service weight of 2000 kg offers 10% more power than its predecessor, the HB 200. The new HB 3100 and HB 4700 with a service weight of 3100 and 4700 kg, respectively, deliver 5% and 13% more power than their predecessor models.
