Designed to satisfy the specific demands of rental fleet operators, the 555E is designed for optimum carrier compatibility and installation flexibility. The 555E features a pivoting hose connecting block and a reversible manifold that allows for right or left hand hose connections, in addition to it's ability to accept a wide range of oil flows and pressures. The Rammer 555E 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.
Twin handed, smart
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.
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.
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.
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.
- Asphalt Cutting
With special compacting plate tool.
