Security from a single source


Tried-and-tested operations and new innovations.

Safety in rescue operations in shaft construction is about far more than just the machinery – it is the combination of reliable equipment and expert operation.

When it comes to the long-term tasks undertaken by RAG Aktiengesellschaft, we rely on a strong partnership: OLKO-Maschinentechnik GmbH provides the innovation, whilst THYSSEN SCHACHTBAU GMBH assumes operational responsibility for the rescue technology.

Operational responsibility: The KN20 in action
The KN20 rescue winch forms part of RAG’s own fleet, but ensuring it is ready for use is our responsibility. THYSSEN SCHACHTBAU GMBH is responsible for the day-to-day operation and maintenance of this main rescue winch.

  • Operational excellence: Our teams ensure that the KN20, as the backbone of the infrastructure, is ready at all times.
  • Expert service: Operation by THYSSEN SCHACHTBAU ensures that this tried-and-tested technology maintains the highest safety standards.
  • Continuity: We know every screw in the existing fleet and guarantee the smooth running of the systems.

Expansion through innovation – the new TS-NOT01 mobile rescue winch from OLKO-Maschinentechnik!
We have channelled this wealth of operational experience directly into the development of our new TS-NOT01. It complements RAG’s fleet where state-of-the-art requirements meet mobile flexibility.

  • State-of-the-art engineering: Fully electronic control system for maximum precision.
  • Specialised solution: The perfect complement for complex scenarios in modern mine drainage and constantly evolving rescue concepts during the refurbishment of mine shafts.
  • Future-proof – integrated sensor technology for real-time digital monitoring.

A strong commitment to the Ruhr mining region!
Whether as operators of the tried-and-tested infrastructure (KN20) or as manufacturers of state-of-the-art technology (TS-NOT01), THYSSEN SCHACHTBAU and OLKO-Maschinentechnik ensure that the shafts in the Ruhr mining region remain safe for use.

Engineering and day-to-day operations – working hand in hand!

Glückauf!
