Rio Tinto – Self-Locking Jack

Rio Tinto's self-locking jack is a finalist in the 5th Annual Australian Mining Prospect Awards for its ability to reduce the safety hazards associated with lifting heavy loads.

The Self-Locking Jack reduces the risks from moving supports under suspended heavy loads.

Mobile Supervisor Wayne Nealon and Reliability Engineer Myles Huntly from Rio Tinto’s Mt Thorley Warkworth Mine identified the issues associated with current equipment.

They discovered there was no suitable product on the market which would alleviate the safety concerns. Nealon and Huntly formulated a self-locking stabilising jack which features a built-in ratcheting device that progressively locks in as the jack’s load is raised.

The completed jack has been introduced into Mount Thorley Warkworth’s maintenance operations.

The jack makes it simpler to lift and support machines that are not running.
