Three moving parts for less maintenance and more up-time
- Oil and gas operation
Improves efficiency by reducing demand on carriers hydraulic system
- Long-stroke design
Minimizes recoil and reduces stress on carrier
- Top-down lubrication
Extends the service life of the demolition and tool bushing
- Select-Start System™
Allows hammer to be operated in one of two start-up modes
- Auto Shut-Off (when down pressure diminishes, the hammer switches off automatically)
- Easy Start (starts hammer with minimal down pressure)
- AutoControl
Regulates blow energy and frequency by monitoring tool penetration
- Guardian DustProtection™
Sophisticated dust deterrent designed for severe applications (Available only on Guardian version Hy-Rams)
