Advanced Technology!
Innovative Service!

  • Through our long experience as a dedicated manufacturer of hydraulic breaker, QKLASS have learnt to know that the definitive quality is a combination of production quality and service quality that moves customer’s mind. Which is our simple philosophy.

Over 20 Years’ Field Approved
Engineering Know-how’s

  • Good quality comes from a good design.
  • More than 20 years engineering know-how's for increasing performance while securing durability enable QKLASS breakers operate very stable constantly in any kinds of operational environment.
  • With an optimized main power cell design and its housing combinations, QKLASS breakers operate is reliable in many different kinds of working conditions.

The Most Durable Gas-hydraulic Breaker

  • Quality material is the first requirement for the good durability.
  • The use of fully tested raw materials, robust design of parts component and housing structure, multi-phase heat treatment process operated by a dedicated engineer ensures components durability.
  • QKLASS breakers are known as the most durable gas hydraulic type breaker in the world.

Challenge to the Zero-defect-level Quality

  • Utilizing computerized automatic machinery such as MCT, CNC, major components are to keep standardized tolerance and clearance.
  • Above all, our own 'Lean Manufacturing System' minimize conventional manufacturing failures that might lead to serious problem in main power cell parts.

Innovative Dealer Support Program

  • Stocks of several kinds of replacement parts are being kept to respond to customer's request to ship for our warranty service. To increase technical support ability of our dealers, we provide many kinds of training program.
  • We continue to develop new technology to enhance usability not to mention power and durability. Thus, the end-users will be satisfied with service as well as product quality through their usage experience.

Features & Applications

  • QKLASS breakers operate under a combined oil and gas pressure.
  • The nitrogen chamber in the upper portion is designed to absorb piston recoil and recycle the energy to increase the next blow power.

K Series

'Cylinder-embedded-valve' without accumulator

  • Simplified oil flow design enables to increase impact energy.
  • High power-to-weight ratio
  • Easy maintenance with fewer components

KA Series

'Cylinder-embedded-valve' with accumulator

  • Accumulator creates higher impact force while minimizing pulsation.

G Series

'Outer-mounted-valve' with accumulator

  • Good maintenance value using many interchangeable consumable parts
  • Accumulator creates higher impact force while minimizing pulsation.

Safe Operation Guide

ASF(Auto-Stop-Firing) Device

  • ASF Off mode : Useful for the place where the rock condition is constant
  • ASF On mode : Useful for the place where the rock condition is not constant and the operator is not fully experienced in preventing from 'Blank Firing'


- Utilizing anti-shock-bolt, impact power and bpm keeps constant when ASF is on.
