Description

This SB121 hydraulic rock breaker is a heavy-duty SB121 excavator breaker fitted with a 155mm chisel, a high-power 20-30t digger attachment ideal as a quarry breaking hammer and large mining rock breaker for rock quarrying & concrete demolition.

Built with an integrated body and built-in accumulator, it delivers powerful impact and stable frequency to crush granite, basalt and reinforced concrete. Optimized oil circuits reduce overheating during nonstop work and solve common issues like power loss and oil leakage. The thick shell, forged wear-resistant chisel and imported seals cut maintenance downtime, making it the preferred breaking attachment for mines and engineering firms worldwide.
