OLKO-Maschinentechnik GmbH supplies you with high-quality head frames, shaft towers and shaft installations. We have built and maintained numerous head frames, and upgraded others  during operation to cope with higher loads. Our frames are usually designed as trestle and brace frames.


In our shaft towers, we either arrange the hoisting winder as part of the tower itself, on the uppermost stage, or fit it at platform level.

OLKO shaft-sinking machines and systems have been built for German coal mines and operated in conjunction with domestic and foreign shaft construction companies.

The following OLKO components are nowadays considered essential to the sinking of new shafts.

  • Shaft-sinking equipment
  • Sinking frames
  • Sinking platforms
  • Gripper systems
