Hydraulic Breakers

The HB 2000 and HB 4700 are the newest models in Atlas Copco’s heavy hydraulic breaker line. The HB 2000 has a service weight of 4,409 lb. The HB 4700 has a service weight of 10,362 lb and rounds out the range of the company’s breakers to cover all modern excavator sizes. Both have VibroSilenced System to reduce noise and protect the operator and carrier against vibrations; AutoControl adapts the blow frequency and impact energy to the material hardness; an integrated automatic lubrication system; StartSelect, which allows the operator to choose the startup and shutdown process of the breaker to match the application at hand;  and an optional  two-stage seal system that protects the hammer unit and bushings against damage from dust and rock particles in the lower part of the breaker.
