Rammer 4099E Hydraulic Hammer
YZH
Product Description
The 4099E comes standard with an idle stroke prevention system. This essential feature protects the hammer from damaging idle strokes, significantly reducing wear and tear and extending its service life.
The hammer is protected by a robust, heavy-duty housing designed for maximum durability. The sound-suppressed design minimizes noise and vibration, enhancing operator comfort and safety while providing excellent visibility and accessibility in tight spaces. ,
The 4099E is equipped with Rammer’s most advanced systems:
RD3/SAM Remote Monitoring: Track operating hours, service intervals, and GPS location to optimize fleet management and maintenance.
Ramlube II Automatic Lubrication: Ensures the hammer is always properly greased, reducing wear and minimizing downtime.
Ramvalve Overflow Protection: Safeguards the hammer from excessive hydraulic pressure, preventing costly damage.
Easily switch between long and short stroke settings to match the hammer’s frequency and power to the application. Use the long stroke for powerful, primary breaking and the short stroke for faster, secondary breaking tasks, maximizing productivity.
