The Rammer 2166E hydraulic hammer is suitable for carriers in the 16 to 26 tonne range. The 1400 kg hammer with an impact rate of 430 - 790 blows per minute features Rammer’s Fixed Blow Energy operating principle, which ensures optimum impact energy with every blow, regardless of hydraulic flow fluctuations. The Rammer 2166E comes with the remote monitoring hardware RD3 installed.
More efficient than relief/check valves, Ramvalve detects overflow, prevents damage from system overload and protects against premature failure.
Ramlube I (Optional)
Carrier mounted greasing device
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.
Ramlube II (Optional)
Mounted greasing device, with adjustable flow and cartridge feed.
Membrane type accumulator
Membrane-type accumulator eliminates Nitrogen leakages, ensuring constant maximum impact power and eliminating the need for recharging in field.
Air connection for e.g. dust protection.
FBE (Fixed blow energy)
The built-in pressure control valve maintains hydraulic pressure levels to ensure that every blow delivers the maximum power, yielding optimum productivity in all applications.
Sound Suppressed Heavy Duty Housing (round corners)
Heavy duty housings feature a robust structure, are made of wear-resistant steel, with minimum number of holes and heavy duty wear plates for optimum vibration- and noise dampening.
Resulting in a longer housing lifetime even in the harshest of applications, reducing the cost of ownership through less maintenance.
- Fast-change tool system
Factory installed RD3 for MyFleet
RD3 for MyFleet as standard. Online hour meter and location tracking in Google MapsTM
VIDAT tie rods
Vibration Dampened Tie Rods, spherical tie rod nuts and damper bushings ensures piston moves freely for longer, more productive working life.
Indexable power cell (left or right handed)
The ability to rotate the powercell 180 degress is part of the twin-handed design, allowing for optimal mounting on both left and right handed carriers, prolonging the service life of the hose connections.
Air connection as standard for connection to either Ramair or applications under water. Read the operator's manual and consult with your dealer.
Field replaceable lower tool bushing
Field replaceable lower tool bushing eliminates transport to service workshop.
Hydraulic excavators have largely replaced cranes with wrecking balls, enabling demolition to be carried out in a much more controlled and efficient manner.
Demolition of rubble on the ground, separation of rebar from concrete and preparation of material for further recycling, e.g. as landfill or others.
Trenching is a form of primary breaking in which a narrow trench is excavated especially for laying pipes, cables or for installing drainage
Boom mounted applications
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.
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.
