Fully hydraulic quick couplers

QS45—QS80

For excavators weighing 6—33 tons

Q-Safe™ – The safest quick coupler in the world! For all excavators between 13,200-72,600 lbs.

Q-Safe™ Features

  • The EC-Oil automatic quick coupler system connects the tiltrotator & hydraulic tools without the operator needing to leave the cab.
  • Hydraulic locking with fourfold safety:
    1. Electronic sensors detect when both pins have contact
    2. A check valve prevents the hydraulic cylinder from opening even if a hose ruptures or there is a pressure drop
    3. Powerful, exterior springs keep the coupler locked even if the electronics and hydraulics fail.
    4. The unique design of the lock bolt provides additional safety as the bucket axle bottoms against the coupler side plates and cannot therefore drop out of position even if all three of the above steps should fail.
  • The tool can only be removed when it is resting on the ground at a given pressure (with QSC). This eliminates the risk of dropped buckets.
  • Front and rear locks eliminate the risk of accidents caused by swinging tools
  • Q-Safe is supplied as standard with external audible and visible warning signals to alert the surrounding area
  • Play-free design with double contact surfaces compared to many other coupler systems
  • Longer hooks (shark jaws) to make picking up tools safer and easier
  • Welded high-strength steel
  • Fits all excavators in the specified weight class independent of control system
  • The hook is classified for safety in compliance with:
    EN ISO 12100-1/A1:2009 and
    EN ISO 12100-2/A1:2009
  • Q-Safe is also fitted as standard equipment under engcon tiltrotators with coupler sizes S45-S80.
