Features

High Performance

        
  • Automatic shut off offers blank firing protection by stopping the piston when there is no material under the tool to help extend the life of the hammer.
  •     
  • The internal buffering system helps reduce machine vibration and increase noise suppression.
  •     
  • The standard silencing feature allows you to use a Performance hammer on job sites in noise-sensitive areas like neighborhoods or near hospitals where noise is regulated.

Increase Productivity

        
  • 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 oil-fired operating cycle helps provide full power during every blow and less waste heat.
  •     
  • Critical hydraulic components are shielded from damage inside the housing, helping decrease downtime on the job site.

Easy to Maintain

        
  • Standard on-board autolube provides continuous greasing as the hammer runs, eliminating the need for manual greasing.
  •     
  • The slip-fit and 90-degree rotatable lower bushing allows for easy replacement in the field, helping reduce service time and extend service life.
  •     
  • The oil-fired design eliminates the need to check gas charge.
  •     
  • 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.
