Features & Applications

Features
- High pressure membrane accumulator
  Membrane-type accumulator eliminates Nitrogen leakages, ensuring constant maximum impact power and eliminating the need for recharging in field.
- Twin handed, smart
  A connecting block allows easy adaptation to different excavator setups. This twin handed design allows optimal mounting on both left and right handed carriers, prolonging the service life of the hose connections. Easy installation with hydraulic quick hitch mounting brackets.
- Tubular accumulator
  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.
- Vibration and sound suppressed
  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.
- Flange mounting
  The Flange mounting design allows for the use of existing mounting plates, as well as carrier and application specific customization.
- CBE+ (Constant Blow Energy plus)
  The RAMMER CBE-System (CBE = Constant Blow Energy) with the active pressure control valve and the permanently filled tubular accumulator maintains the hydraulic pressure level to ensure that each impact delivers the maximum possible power. The RAMMER CBE system accepts a wide range of oil flows and high back pressures, allowing a wide range of carriers to be used. The "+" stands for safe and fast connection to the carrier.
- No tie rods
  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.
- Single part tool bushing retained with shared tool pin
  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.
- RD3 incl. SAM (as standard)
  RD3 for SAM as standard. Online hour meter and location tracking in Google MapsTM. For further information, please contact your Rammer distributor.
Applications
- Primary demolition
  Demolition of standing buildings and structures.
- Trenching
  Trenching is a form of primary breaking in which a narrow trench is excavated especially for laying pipes, cables or for installing drainage
- Secondary demolition
  Demolition of larger pieces on the ground (size reduction, separation and preliminary sorting tasks)
- Cutting of asphalt or frozen ground
  The RAMMER "Spade tool" was specially developed for cutting of asphalt or frozen ground in road construction or infrastructure.
- Landscaping
  Gardening, graveyard and landscaping applications, hard ground and removal of smaller boulders, concrete fundaments or similar.
- Ground Compacting
  With special compacting plate tool.
- Rental
  Rental includes most applications
