Designed for extreme applications. The 600 kg 999E Heavy Duty hydraulic hammer is suitable for carriers in the 3.9 to 13 tonne range.
Robust housing of the Rammer 999E withstand wear and no-tie-rods enables fast and easy servicing. Twin handed design allows optimal mounting on both left and right-handed carriers, prolonging the service life of the hose connections.
The 999E Heavy Duty Small hammer comes with remote monitoring device RD3 installed.
Membrane-type accumulator eliminates Nitrogen leakages, ensuring constant maximum impact power and eliminating the need for recharging in field.
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.
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.
The Flange mounting design allows for the use of existing mounting plates, as well as carrier and application specific customization.
Heavy duty housings feature a robust structure, are made of wear-resistant steel, with minimum number of holes.
Resulting in a longer housing lifetime even in the harshest of applications, reducing the cost of ownership through less maintenance.
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.
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.
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.
Quick and safe tool change system transverse to the hammer. No need to reach under the hammer during tool change.
RD3 for SAM as standard. Online hour meter and location tracking in Google MapsTM.

Hammers for use on crushers to ensure unrestricted flow of process. Removal of boulders which are too large to fit into crusher or which block the grizzly.
Absolutely necessary to ensure safe working procedures.
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)
The RAMMER "Spade tool" was specially developed for cutting of asphalt or frozen ground in road construction or infrastructure.
