The SB70 hydraulic breaker is based on South Korean engineering that prioritizes a streamlined hydraulic circuit. With fewer internal components than many competitors, it is significantly easier to maintain and repair in the field. It is a reliable choice for standard demolition where consistent, heavy blows are more important than extreme speed.
Best For: Projects requiring high uptime and low maintenance costs.

HB20G hydraulic hammers
The HB20G hydraulic breaker follows the Furukawa-series design tradition, offering a higher impact frequency (up to 800 bpm). This makes it exceptionally efficient at breaking up reinforced concrete and medium-hard rock. It often features a slightly heavier operating weight, providing better stability for larger 20–25 ton machines.
Best For: High-production demolition and quarrying where speed and efficiency are critical.
Key Advantage: Superior blow speed and advanced heat treatment on the piston for longer service life.
About the price: SB70 Hydraulic Breaker Price is a little lower than HB20G Hydraulic Breaker.
Choose the SB70 rock hammer if you want a reliable, low-cost hydraulic breaker that is easy to service. It is the better choice for general construction where downtime must be kept to a minimum.
Choose the HB20G rock hammer if you need maximum impact speed for breaking hard granite or reinforced concrete. Its higher blow rate makes it more efficient for high-volume rock excavation.
No matter which type of hydraulic breaker you choose, we provide a one-stop rock breaker hammer solution with a one-year warranty.
Our technical engineers help you win engineering and construction projects, reduce costs, and improve work efficiency. To date, we have completed numerous projects for clients in countries such as Saudi Arabia and Libya. Check our HB20G hydraulic breaker projects case.
