SolidBody concept

Integrates percussion mechanism and guide system into a single block of special cast iron, decrasing 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 copmact shape to simplify handling. A replaceable piston liner supports low repair cost.


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