Specifications

  1. Energy Regeneration Nitrogen Gas Cushion Chamber (ERNGCC) Absorbs the piston's upward recoil and conduct energy recycling for the constant blow.
  2. Side Buffer Side vibration absorber and side suspension device to protect the powercell.
  3. Easy-Pass Valve Side mounted type of "Easy-Pass Valve (EPV)" as a spool to regulate smooth oil traffic and t control the oil direction for the stable operation and the vibration absorbing.
  4. N2 Gas Charged Accumulator Rechargeable N2 gas accumulator to assist power stroke and to reduce the surge pressure and the spikes from the hydraulic circuit of the excavator.
  5. Piston Most efficient design for maximum energy transfer and recoil reduction as well as ideal match of tool and piston diameters. It transfers highest shock wave into the breaking objects.
  6. Efficient Power Transfer (Piston to tool) Optimum transfer of blow energy into the material and the reduction of the recoil.
  7. Dual Tool Retainer Pins Correct tool alignment and dispersion of tool wear.
  8. Housing Bottom Plate Abrasion-resistant plate delivers breaker protection.
  9. Working Tool Heat treated and optimal length for efficient breaking.
  10. Replaceable Tool Bushing Convenience for replacement and protect the front head. (Not shown on the illustration)
  11. Wearing Plates Employment of wear resistant plates between cylinder, front head and housing increases the overall product durability.
  12. Auto Grease Refiller Compact auto grease refiller is equipped as an optional feature. Easy daily refill is serviced and continuous greasing is available as long as the breaker is operated. (Not shown on the illustration)
  13. Double Speed System As a standard feature to change from long stroke to short stroke according to the operator's requirement for the optimal performance. (Not shown on the illustration)
  14. Underwater Application (UA) Air line for underwater use. (Not shown on the illustration)
  15. Super Anti Blank Firing (SABF) System SABF increases the lifespan of all components subject to wear and fatigue and reducing stress for the arm of the main carrier and the breaker. (Not shown on the illustration)
  16. All-In-One Type of Upper Bushing and Thrust Ring Integration Convenient one set and easier maintenance and serviceability without disassembly of powercell.
  17. Cylinder Design Square typed cylinder design brings optimum match between back head and front as well as improves stable operation to increase the product durability and to reduce the unnecessary damages such as scratches.
  18. Base Buffer Vibration absorber and suspension device to protect the powercell.
  19. Side (Tie) Rods Fully closed side (tie) rods enlarges the durability and the optimal load carrying capacity is designed.
  20. Top Buffer Vibration absorber to prevent the impulses between the carrier and the breaker.

SUPER ANTI BLANK FIRING (SABF)

The operator can selectively adjust On & Off Modes of Anti Blank Firing function according to the given working condition.

Super Anti Blank Firing On

  • In SABF On mode, the hammer automatically starts when the tool presses down the workpiece and automatically stops when the tool tip is no longer in contact with the material.
  • The operator can efficiently control the hammer operation even in poor visibility such as underwater.
  • Internal stress, especially on the tool-retaining components such as the tool pin, front head, side rod, is reduced, providing increased hammer lifespan.

Super Anti Blank Firing Off

  • In SABF Off Mode, the operator can save time to position the breaker. This provides great productivity through increased efficiency of hammer operation.
