The Rammer 155E is one of the fastest hitting hydraulic hammers. The 90 kg hammer is suitable for carriers in the 0.6 to 1.8 tonne range.
The Rammer 155E hammer features an integrated tubular membrane type accumulator which maximizes its surface area, to deliver the maximum breaking power.
The 155E comes with the remote monitoring hardware RD3 installed.
The twin handed design allows optimal mounting on both left and right handed carriers, prolonging the service life of the hose connections.
Easy installation for hydraulic quick hitch mounting brackets.
The leak-free tubular accumulator is filled with nitrogen and requires no maintenance or time-consuming recharging between maintenance intervals.
With its large surface area and short hydraulic connections to the piston, it effectively reduces pressure fluctuations in the hydraulic system and ensures maximum piston acceleration and high impact frequency.
This design provides 100% power at all times.
Less vibrations and at the same time significantly lower noise levels are achieved with this ultra-modern, low-wear design.
This protects the operator, the carrier and relieves the environment.
This extends your range of applications on narrow job sites and wherever noise protection is required.
Pin or bracket for quick hitch or direct mounting
The pressure release system (PRS) allows for the faster and safer removal of hose connections when dismounting.
A smart design without tie rods allows for ideal guidance of the piston and optimal alignment of the tool.
Fast, safe and easy to maintain without the need for special tools.
The one-piece quick-change tool bushing inludes a thrust ring, the upper and the lower tool bushing into one component.
This quick-change tool bushing can easily be replaced on site, making maintenance easier, faster and safer.
Quick and safe tool change system transverse to the hammer. No need to reach under the hammer during tool change.
RD3 for SAM as standard. Online hour meter and location tracking in Google MapsTM.
