New machine to reduce risk and strain

A NEW machine to reduce the risk and “manhandling” involved in installing ore car connecting pins will soon be operating at the wagon workshop.

A new machine to reduce the risk and “manhandling” involved in installing ore car connecting pins will soon be operating at the wagon workshop.

The Mobile Pneumatic Pin Lifter, which has been designed by Rio Tinto Iron Ore graduate mechanical engineer Aaron McGrail and Perth-based company Tyco Motion and Control, aims to make this regular task safer and more ergonomic.

Aaron said the project was a true team effort, with wagon maintenance personnel actively involved in assessing the prototype and suggesting further improvements to the company designing the machine.

“Any machine used for installing ore car connecting pins had to be light, mobile, easy-to-use and obviously able to get under the ore car and install the pin,” he said.

“The result has been a machine designed in collaboration with Tyco Motion and Control that uses a multi-stage pneumatic cylinder mounted in a frame and wheels.

“Wagon maintenance personnel have had an opportunity to review the prototype and make suggestions for improvements. The result should be a tool that makes this important task safer and easier for everyone involved.”
