Our features make the difference

Our unique design concept with a SolidBody stands for high reliability, extreme versatility, high efficiency, and performance, and is known as very maintenance friendly.

SolidBody Concept

Integrates percussion mechanism and guide system into a single block of special cast iron, decreasing the total number of parts. It also eliminates components like damping and guiding elements and tie rods or stud bolts completely and results in an extremely slim and compact shape to simplify handling. A replaceable piston liner supports low repair cost.

Energy Recovery

The piston recoil energy is automatically utilized to increase the performance without additional hydraulic input and to lower vibrations.

Air and water inlet

to connect the compressed air supply and an integrated water channel for dust suppression (for SB 152 -SB 1102, water nozzles as option)

Floating bushing

Tool bushing with floating fit for easy exchange on-site with standard hand tools

Pressure relief valve

Built-in valve to protect against overloads

Dust wiper

Integrated dust wiper to extend the service life of bushing and retainer bars


The hydraulic breaker starts without load applied to working tool thus simplifying handling

Patented tool locking system

Combining a lock buffer and solid pin for quick tool exchange
