2023 Rammer® Scaler Range Hydraulic Rammers 777E Scaler

2023 Rammer® Scaler Range Hydraulic Rammers 777E Scaler

Made to withstand harsh conditions of scaling. The 415 kg Rammer 777E Scaler is compatible with carriers in the 2.6 to 9.5 tonne range. The 777E Scaler features robust yet easily repaired housing with the floating seal between the tool and the housing patented by Rammer. This hammer have safe and quick tool change system. Connections for grease, air and water and optimized application-specific operating pressure.

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.
