Abstract
This thesis explores the development and preliminary operation of a new test method for roller and roller path arrangements on ultra-class mining shovels. The lack of existing lab-scale test methods discourage significant change, and restrict the development of the roller and roller path to minor adjustments to their geometry and material. Once in full operation the test method will allow for the optimization of existing, or the development of new, roller path technology for specific mining conditions. Preliminary testing has shown that with some improvements, the developed apparatus is capable of producing end-of-life roller path samples in four weeks of continuous operation. The impact of various damage models could then be characterized for sensitivity to provide further information on how to develop the optimal roller and roller path system. With further development, the test method developed here would allow for improving the roller and roller path technology at a more rapid pace. Improved rollers and roller paths would reduce the required maintenance time for a mining shovel, decreasing maintenance costs and increasing production.
