Benefits

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.
  •     
  • The slip-fit lower bushing allows for easy replacement in the field, helping reduce service time.
  •     
  • Verify the gas charge of the hammer without removing it from your machine.
  •     
  • Quick and easy access to maintenance areas helps make hammer maintenance simple.

Boost Efficiency and Productivity with Integrated Technologies

        
  • Never waste time looking for your attachments again. Cat asset tracking is available on all hammers.
  •     
  • Track your entire fleet of attachments and machines from one source. Hammers with asset tracking can be viewed within VisionLink®.
  •     
  • Keep your assets secure. Hammers with an asset tracker send an alert if they leave an easy-to-set-up site boundary.
