IHC S-2500

This IHC S-2500 hydraulic underwater hammer is a universal pile-driving tool for use in air and under water. It is the world’s largest IHC piling hammer.

The hammer generates an energy level of up to 2500 kNm. One advantage of this type of hydraulic hammer is that the energy applied per blow can be continuously adjusted from 5 to 100% during the piling operation. The hammer is computer controlled, which enables the operator to adjust the hammer’s performance parameters very precisely. The computer registers every blow so that an accurate pile report can be created.

The hammer can be equipped with the world’s largest sleeves which are currently 6,5 meters in diameter.
