Liner Lifting Tools

After an extensive Research and Development effort the O-ZONE Liner Lifting Tools range was added to the Mill Relining System suite of technologies in 2007. The idea was borne out of the problem of how to safely and quickly secure worn and new liners so that they can be moved with the Mill Relining Machine or Mill Liner Handler. Prior to the invention of the O-ZONE Liner Lifting Tools, crowbars and slings made of a variety of materials were used, and many reline operators suffered crush injuries as a result. Saving one minute per liner while simultaneously improving safety, the O-ZONE range of Liner Lifting Tools consists of:

  • O-ZONE Scissors
  • O-ZONE Grips
  • O-ZONE Hooks

In a 300 liner ball mill reline, the inclusion of O-ZONE Liner Lifting Tools saved another five hours downtime.
