Liner Lifting Tools

O-ZONE Liner Lifting Tools were developed with insights won from Stephen Kittel’s Time and Motion Studies. RME were determined to identify the best method of safely and quickly securing worn liners so that they could be moved with the Mill Relining Machine or Mill Liner Handler during ‘Mucking Out’.

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.

The below diagram shows how the range of O-ZONE Liner Lifting Tools work together.

RME’s patented O-ZONE Scissor tools engage worn liners which fall face down and are without retained liner bolts. The Scissors are closed, inserted and expanded within the worn liner bolt hole.

RME’s O-ZONE Hooks and Rigging Chains adapt between the Mill Liner Handler/Mill Relining Machine lifting hooks and any of the O-ZONE Liner Lifting Tools. The specially designed hook is necessary to lock the O-ZONE Scissors.

RME’s O-ZONE Grip tools engage worn liners which fall face down with retained liner bolts. The O-ZONE Grip simply slides over the exposed bolt thread.
