Screw Jacks for the Steel Industry

There are many advantages of screw jacks (mechanical actuators) compared to hydraulic solutions, examples are:

  • Screw jacks with self-locking capabilities (the load will not lower in event of an electrical failure)
  • High repeat and position accuracy
  • Robust and reliable system designs
  • Total synchronization in the case of multiple screw jack lifting systems
  • Ready and easy to install
