Excavator jack hammers are impact devices designed to break any kind of rock or concrete with any hardness or physical property. They have a wide range of applications such as demolition, deconstruction, primary rock excavation, secondary rock breaking, trenching, foundation work, asphalt cutting and many others.
Common Characteristics
• Hybrid technology - Integrated nitrogen piston accumulator for constantly high impact energy, safe start-up and smooth operation
• VibroSilenced Plus - Non-metallic suspension arrangements to isolate percussion mechanism from breaker box and sealing of all openings for lower noise and vibration levels
• Advanced control technology - The integrated control valve optimizes efficiency; the EnergyRecovery system increases operating efficiency and lowers vibrations
• Monoblock design - Combined cylinder & tool holder section eliminating the need for tie rods for higher reliability; replaceable piston liner for cost-effective repairs
• Field replaceable bushing - Full length floating tool bushing for quick exchange with standard hand tools
