2023 Rammer® Small Range Hydraulic Rammers 555E
The Rammer 555E is designed for optimum carrier compatibility and installation flexibility in the 1.9 to 8 tonne range. The 275 kg hammer 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 555E is designed to satisfy the specific demands of rental fleet operators. The 555E comes with the remote monitoring hardware RD3 installed.
Features may include:
High pressure membrane accumulator- Membrane-type accumulator eliminates Nitrogen leakages, ensuring constant maximum impact power and eliminating the need for recharging in field.
- 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.
- The leak-free tubular accumulator is filled with nitrogen and requires no maintenance or time-consuming recharging between maintenance intervals. With its large surface area and short hydraulic connections to the piston, it effectively reduces pressure fluctuations in the hydraulic system and ensures maximum piston acceleration and high impact frequency. This design provides 100% power at all times.
