Features & Applications

Features
- Low pressure accumulator
  This accumulator accelerates the piston at constant energy (CBE).
- 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)
  Optimum impact energy for every stroke, ensuring 100% constant power and productivity
- Light weight
  The light weight design allows the use of smaller carriers without compromising the stability of the carrier.
- Idle blow protector
  The Idle Blow Protection (IBP) ensures the hammer cannot be operated until pressure is placed on tool. This eliminates tie rod stress, reduces oil overheating and protects against premature failures.
- 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.
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)
- Recycling
  Re-using parts or material which has been extracted from existing buildings or structures. Recyclng of products: Re-use of material or parts as such Recycling of material: Re-use of material for other purposes
- 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.
- Underwater breaking
  Underwater breaking, be it primary breaking and/or demolition is a specialized application, in which material is broken and removed by equipment which is partly or fully submerged.
