The 255E is your no fuss solution for carriers between 0.9 and 2.5 tons. Protected by their box type housing, these hammers produce less noise and vibration, whilst they are strong enough to take a beating. The Rammer 255E comes with the remote monitoring hardware RD3 installed.
The Flange mounting mounting design allows for the use of existing mounting plates, as well as carrier and application specific customization.
Single part tool bushing retained with shared tool pin
Single part tool bushing with long bearing surface and thrust ring maximizes tool and bushing life lowering operating costs. Whilst being field replaceable and easy to remove allows faster and easier field service lowering maintenance costs.
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.
Membrane type accumulator
Membrane-type accumulator eliminates Nitrogen leakages, ensuring constant maximum impact power and eliminating the need for recharging in field.
- Vibration and sound suppressed
Factory installed RD3 for MyFleet
RD3 for MyFleet as standard. Online hour meter and location tracking in Google MapsTM
- CBE+ (Constant blow energy plus)
No tie rods
Fast and easy to service with no special tooling required.
Hydraulic excavators have largely replaced cranes with wrecking balls, enabling demolition to be carried out in a much more controlled and efficient manner.
Gardening, graveyard and landscaping applications, hard ground and removal of smaller boulders, concrete fundaments or similar.
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
The challenge with recycling is to combine strict environmental controls with cost-efficient methods to make recycling an economically viable proposition.
- Asphalt Cutting
With special compacting plate tool.
