Drive systems must function reliably in safety-relevant applications. Our safety nut ensures that there is no uncontrolled load reduction in the event of a failure of the load-bearing thread.

What requirements apply to screw jacks in safety-critical applications?

In many industrial applications, drive systems must fulfil specified safety standards – especially for vertically guided loads.

What safety solution does ZIMM offer for screw jacks?

With the safety nut, we offer a tested safety component that is available for both spindle versions:

  • Rotating spindle
  • Translating spindle

How does the safety catch nut work?

The catch nut moves with the load during operation. If the load-bearing thread fails, it immediately takes up the load and prevents the movement unit from dropping.
