2023 Rammer® Heavy Duty Small Range Hydraulic Rammers 777E Heavy Duty

Heavy-duty Rammer 777E has been made for demanding conditions. The 415 kg hammer is suitable for carriers in the 2.6 to 9.5 tonne range. Robust housing withstand wear and no-tie-rods enables fast and easy servicing. Twin handed design allows optimal mounting on both left and right-handed carriers, prolonging the service life of the hose connections. The Rammer 777E Heavy Duty Small hydraulic hammer comes with remote monitoring device 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.
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.
Tubular accumulator
  • 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.
