OUR FEATURES – YOUR BENEFITS

 

INCREASE YOUR PRODUCTIVITY
  • 1) FBE (Fixed Blow Energy)
    A built-in pressure control valve maintains hydraulic pressure levels to ensure that every blow delivers the maximum power possible for optimum productivity.
  • 2) Membrane type accumulator
    Membrane type accumulator eliminates nitrogen leakages, ensuring maximum piston acceleration and removing the need for time consuming recharging.
  • 3) Stroke selector
    Fitted as standard on all Large range hammers (except 7013) Stroke selector is designed to optimize hammer operating. It allows operator to match hammer to material and application, delivering more frequent, softer blows in softer materials and fewer high impact blows in hard rock.
  • 4) IBP (Idle Blow Protection)
    Fitted as standard on all Large range hammers (except 7013), IBP ensures the hammer cannot be operated until pressure is placed on tool. This eliminates tie rod stress, reduces oil overheating and protects against premature failures.
  • 5) Wide tool selection
MINIMIZE YOUR MAINTENANCE COSTS
  • 8) Ramdata II
    The Ramdata II service indicator is designed to help hammer
    operators and service personnel get information about the service interval status, service history and accumulated working history of the hammer.
  • 9) Ramlube (Different options)
    Rammer offers two types of automatic greasing systems for its Large Hammer Range:
    Ramlube I – Machine-mounted
    Ramlube II – Hammer-mounted
    Both Ramlube devices maintain correct greasing levels, protect the tool and reduce owning and operating costs.
  • 2) Membrane type accumulator Membrane type accumulator eliminates nitrogen leakages,
    ensuring maximum piston acceleration and removing the need for time consuming recharging.
  • 12) TS (Tool Saver) bushing
    Rammer Large range hammers can be equipped as a retrofit
    with a field replaceable insert that increases service life of the tool and tool bushing.
PROTECT YOUR WORKING ENVIRONMENT
  • 6) Heavy duty housing
    Fitted as standard, heavy duty housings feature a robust structure, minimum number of holes and plastic wear plates for optimum hammer protection and noise reduction.
  • 7) Top buffer and side pads
    The unique Rammer vibration absorption system consists of three buffers – one upper buffer and two side pads – that prevent the transmission of vibration to protect both the breaker and the carrier’s boom, stick and swing gears and to isolate the operator
MAXIMIZE YOUR UTILIZATION
  • 6) Heavy duty housing
    Fitted as standard, heavy duty housings feature a robust
    structure, minimum number of holes and plastic wear plates for optimum hammer protection and noise reduction.
  • 10) VIDAT
    Vibration Dampened Tie Rods, spherical tie rod nuts and
    damper bushings ensure piston moves freely for longer, more productive working life.
  • 11) Ramvalve
    Ramvalve detects overflow, prevents damage from system overload and protects against premature failure. Ramvalve is standard on all Large range hammers (except 7013).
