High Performance
Automatic shutoff offers blank firing protection by stopping the piston when there is no material under the tool to help extend the life of the hammer.
Manually adjust the piston speed by choosing between high piston speed or maximum power to help increase efficiency and production on the job site.
The standard silencing feature allows you to use a GC S hammer on job sites in noise sensitive areas like neighborhoods or near hospitals where noise is regulated.
Reliability and Durability
The internal buffering system helps reduce machine vibration and increase noise suppression.
Simple hammer design for easy maintenance and faster rebuilds to help lower owning and operating costs.
Critical hydraulic components are shielded from damage inside the housing, helping decrease downtime on the job site.
Easy to Maintain
Standard onboard autolube provides continuous greasing as the hammer runs, eliminating the need for manual greasing.
