The Rammer R12P is your everyday worker for a wide range of breaking duties for carriers between 9-14 tons. The 830 kg hammer has been designed with proven Rammer features and standards.
The profitable R12P offers more than just excellent power-to-weight ratio, it brings the quality reassurance that only a true Rammer hammer can bring.
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.
Quick and safe tool change system transverse to the hammer. No need to reach under the hammer during tool change.
RD3 device for SAM service available for retrofit installation. Please consult your distributor for proper version.
Online hour meter and location tracking in Google MapsTM
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.
Trenching is a form of primary breaking in which a narrow trench is excavated especially for laying pipes, cables or for installing drainage
Demolition of larger pieces on the ground (size reduction, separation and preliminary sorting tasks)
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.
Gardening, graveyard and landscaping applications, hard ground and removal of smaller boulders, concrete fundaments or similar.
