Proven Working Principle
Pressurised nitrogen gas is the main power source, to operate with less demand on the carrier’s hydraulic system.

Dual Speed Control
Control blow frequency adjusting to hardness of rock

Underwater Application
Allowing hammer submerged in water

Rugged construction
Jigsaw shaped main bracket design achieves better resilience from external force. Sound and long-lasting body structure.

Increased life time of dampers and wear plates
New type of composite 2 layered damper and wear plate has longer lifetime than conventional material. Longer maintenance interval.

Swivel Joint
Produces vibration induced hose failure.
