Rammer 2155 embrases the very latest in hydraulic hammer design with it's slim body, robust housing made of wear resistant steel, a replaceable bottom plate etc. A key feature of the 2155 is its new design that provides its user exceptional flexibility to match the hammer precisely to their application and material requirements by choosing from a range of options as “retrofit”.
The Ramdata II monitors vital functions including working hours, operating method and shift duration, using this information to help predict failures before they occur and schedule service and maintenance.
Ramlube I (Optional)
Carrier mounted greasing device
The twin-handed design allows optimal mounting on both left and right handed carriers, prolonging the service life of the hose connections.
Ramlube II (Optional)
Mounted greasing device, with adjustable flow and cartridge feed.
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 maximum piston acceleration and removing the need for time-consuming recharging.
FBE (Fixed blow energy)
A built-in pressure control valve maintains hydraulic pressure levels to ensure that every blow delivers the maximum power possible optimum productivity.
VIDAT tie rods
Vibration Dampened Tie Rods, spherical tie rod nuts and damper bushings ensures piston moves freely for longer, more productive working life.
Idle blow protector (Optional)
Idle Blow Protection 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.
Soft blow sensor (Optional)
The Soft Blow Sensor SBS slows the product down and reduces power to minimize blank firing damage, making products with the SBS ideal for secondary breaking. This will not effect the power when there is normal contact between tool and material to be broken.
Heavy duty set (Optional)
Additional wear resistant plating and stone claws, increase the wear life of the housing and aid with repositioning in boulder breaking applications.
Trenching is a form of primary breaking in which a narrow trench is excavated especially for laying pipes, cables or for installing drainage
Hydraulic excavators have largely replaced cranes with wrecking balls, enabling demolition to be carried out in a much more controlled and efficient manner.
Low clearance hammer tunneling
Especially in the underground mining industry the tunneling operations do not always allow for enough clearance, this restricts the types of carriers that can work in these environments.
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.
