Powerful and Durable Performance

The KM SB151 hydraulic rock hammer is a strong and reliable breaker built for heavy-duty excavators weighing 40 to 50 tons. It performs exceptionally well in tough tasks like mining, quarrying, foundation demolition, and road construction. Thanks to its reinforced housing and tough 175mm chisel, the SB151 delivers powerful impact energy while also ensuring long-lasting durability.

Efficient Operation

This breaker operates at 90–120 kg/cm² pressure and requires 220–270 L/min oil flow, so it balances power with efficiency. Although it is heavy-duty, it weighs only 4617 kg, which means it provides strong performance without extra bulk. Moreover, it carries CE and ISO certifications, which guarantee it meets global safety and quality standards. As a result, users can rely on it for consistent, long-term use.

Top-Mount Design for Stability and Precision

The top-mount design offers excellent stability and helps reduce stress on the excavator arm. In addition, it gives the operator a clear view, which improves precision and boosts productivity on site. Because of this, users find it easier to work for longer periods with less fatigue. Furthermore, the design simplifies maintenance and increases overall equipment lifespan.

Customization and Warranty

The KM SB151 comes with customizable colors, a 12-month warranty, and OEM services to meet your specific needs. Additionally, it is securely packed in a standard wooden case, so it is ready for fast delivery and easy installation—making it ideal for global markets. Therefore, it is a trusted choice for contractors worldwide.
