Rammer 2155E embraces the very latest in hydraulic hammer design with its slim body, robust housing made of wear resistant steel, a replaceable bottom plate and others. A key feature of the 2155E is its new design that provides exceptional flexibility to match the hammer precisely to application and material requirements by choosing from a range of options as “retrofit”. The Rammer 2155E comes with the remote monitoring hardware RD3 installed.
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.
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.
Ramlube III (Optional)
A built in greasing device, that is ideal for working in colder climates as the grease is warmed allong with the product.
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.
- 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.
- Wheeled Excavator Hammer
Air connection as standard for connection to either Ramair or applications under water. Read the operator's manual and consult with your dealer.
Heavy duty set (Optional)
For the 1533E and the 2155E.
Additional wear resistant plating and stone claws, increase the wear life of the housing and aid with repositioning in boulder breaking applications.
Hydraulic excavators have largely replaced cranes with wrecking balls, enabling demolition to be carried out in a much more controlled and efficient manner.
Trenching is a form of primary breaking in which a narrow trench is excavated especially for laying pipes, cables or for installing drainage
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.
The metallurgical industries can be broadly divided into primary, secondary, and miscellaneous metal production operations.
