F-SERIES

Silent /Box type

Silent hammer series offers low noise level, high impact power for the ideal demolition equipment for the city or residential area.

 - Model : KH-110(S) ~ KH950S

   + Through Bolt - Reduces internal torsion, stress to increases fastener life.

   + Full Box Enclosure - No rigid side-boilts, Low maintence cost, Extremely durable welded structure,

                                    reduces noise, Hammer is completely protected and quieter

   + Long Piston Stroke - Maximized impact energy, Minimizes recoil, Eliminates mechanical springs,

                                   Special heat-treated and hardened piston.

   + Proven Working Pinciple(oil and gas assist) - Pressurized Nitrongen gas is the main power

                                                                         source, to operate with less demand  on the carrier's 

                                                                          haydraulic system.

                                                                          Operate with maximum efficency even on smaller

                                                                          carriers that generate less oil flow. 

  +  Fewer Components -Around one-third as its competitor, around 30 to 90 items depending on

                                     model, Easy maintenc, Dealers need fewere spare parts in inventory, Easy to

                                     rebuild

  +   Perfect Cushion Damper - Optimal damping system made of high quality urethane,

                                            Minimizing recoil shock induced by impact, Reduces noise and vibration.

  +  Wide and light-Weight cover - Noise insulation, Dust protection, Easy Maintance

  +  Easy Maintance - Fewer components, wide and appropriate opening

  +  Hardened rock dragger - Resisting wear and abrasion

  +  High quality working tool - Oprimized by high grade steel and heat treatment

  +  Unique Valve Design for model - Lessens pressure fluctuation, Less damage on carrier's pump

- Model: KH- 1500(S) ~ KH4000(S)-II

  +  Roomier Gas Chamber - Increase impact power

  + Stroke Adjuster - Maximize productivity from variable speed

  + Accumulator - Less stress to hydrualic components as absorbing pressure fluctcation, Increase

                           efficiencey as replenishing oil flow

  +   High pressure Accumulator - Eliminates pressure fluctucation, Increases impact power

  +   Cushion Damper - Absorb reercussion from hammering and increse carrier endurance

  +   Main valve - Internal contrl valve systemis more efficient by 10% to 15% than other breaker's valve, 

                           stay cooler and make the quicker and harder - hitting

  + Piston  - Higher impact power with long stroke

  + Wide Tool Retainer pin - safe from abnormal wearing

  + Rock drgger with anti-abrasion steel = used andti-abrasion steel (Hardox steel)

  + Well heat-treated tool - Longer life by good meterial
