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.
    • Flange mounting
      The Flange mounting design allows for the use of existing mounting plates, as well as carrier and application specific customization.
    • Robust side plate design
      The bolted side plates are designed for extremely tough applications. This robust construction is very easy to maintain and can quickly be repaired.
    • 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.
    • Optimized operating pressure (Scaler)
      With the CBE operating system is RAMMER able to optimize the operating pressure of the hammer regardless of oil flow.  For this application, the operating pressure has been slightly reduced.
    • 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.
    • Fast-change tool system
      Quick and safe tool change system transverse to the hammer. No need to reach under the hammer during tool change.
    • Robust tool sealing
      The floating seal between the tool and the housing is patented by RAMMER and protects the power cell against debris. This extends the service life of the hammer significantly.
    • Connection for external lubrication
      An external lubrication system, such as RAMLUBE I or the AGW, can be connected to the integrated grease hose.
    • RAMLUBE I (optional)
      Carrier mounted greasing device
    • RAMMER Air-Jet
      The transfer line for compressed air, which is an integral part of the hammer. This line connects e.g. the RAMAIR or the AGW air supply to the hammer. The injection of compressed air prevents tool grease and impurities from entering the impact area when working overhead. Thus it prevents excessive wear on piston, seals and tool bushings. Pressurized air forces the tool grease out of the hammer, thus ensuring that the hammer is always lubricated by clean tool grease.
    • Ramair (optional)
      The RAMMER - RAMAIR air supply prevents dirt from entering the hammer housing and the impact chamber in order to achieve longest service life of the RAMMER hammer even in the most demanding applications. It also ensures that the tool grease is conveyed to the tool bushings at any time and in any position of the hammer and that no overfilling occurs. The RAMMER - RAMAIR is particularly recommended for highly abrasive and dusty materials or overhead applications, such as tunneling or robbery work.
    • AGW (optional)
      Air, grease and water
    • RAMMER Water-Jet (dust suppression)
      The integrated dust suppression system, with which a fine water mist is applied under high pressure directly to the area where the dust is generated. The water connection is on the housing of the hammer.

  • Applications

    • Scaling
      Scaling is removal of loose material from the tunnel roof and walls to prevent accidents by falling rocks.
