The Rammer R25P is your everyday solution for a wide range of breaking duties for carriers between 20-29 tons. The 1,650 kg hammer has been designed with proven Rammer features and standards.
The Rammer R25P Performance Line hammer incorporates the latest evolution in long proven breaking technology. The profitable R25P offers more than just excellent power-to-weight ratio, it offers the quality reassurance that only a true Rammer hammer can.
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.
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.
The Flange mounting design allows for the use of existing mounting plates, as well as carrier and application specific customization.
Stone claws are ideal wear parts for material handling, especially useful in boulder breaking and in concrete demolition.
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.
Quick and safe tool change system transverse to the hammer. No need to reach under the hammer during tool change.
The RAMLUBE II is a state-of-the-art, convenient and automatic lubrication system for RAMMER hydraulic hammers, which significantly extends the service life of wearing parts.
The RAMLUBE II is mounted on your hammer housing and is a self-venting impulse lubrication system.
The grease volume of the RAMLUBE II can be externally adjusted.
We recommend to use our original Rammer tool greases, which are developed for hammer applications.
There are available three different greases: original Rammer Tool Grease for standard applications, Rammer Meissel Paste for special applications and Artic Tool Grease for cold climate conditions.

All our experience reflects the unique quality and reliability of RAMMER original tools.
You are advised to choose the right RAMMER tool for every application. This will increase your production and reduce your costs.
The nitrogen piston accumulator is a safe and durable design, thanks to the use of the latest sealing technologies, .
Fail-safe operation, high impact energy and simple and fast service help to improve your operating results.
RAMMER sets the standard in the industry with these outstanding values in the power-to-weight ratio.
The impact force has been increased and at the same time the operating weight has been optimized.
Demolition of standing buildings and structures.
Demolition of larger pieces on the ground (size reduction, separation and preliminary sorting tasks)
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
Hammer fitted to an excavator working directly in a bench to breaks away rock which can then be removed by truck. This is most commonly used where blasting is not allowed.
When blasted rock is too big for the feeder or crusher, secondary breaking is needed to get the boulders down to size. The type of rock dictates the effectiveness of the process, with brittle rock giving the best performance.
