Cutler is one of the industry’s leading specialists in earthmover tyre management and brings more than four decades of mining and OTR tyre experience to his new company and its clients utler’s journey in the mining industry began with graduation from the University of Queensland with a Bachelor of Mining Engineering degree, after which he joined Hamersley Iron in 1974 as a graduate engineer at Paraburdoo. His career progression started at the bottom – working as a pit labourer on the cable crew manually feeding heavy electric shovel and drill power cable into and out of a ‘boat’ towed behind a Caterpillar 824 dozer. He progressed to haul truck driver, drill offsider, haul truck instructor and mine production foreman. He finally moved into an engineering role, initially as a grade control engineer – which was relatively complex at Paraburdoo because of the heterogeneous, high impurity nature of the orebody – and then as a mine planning engineer. He joined Otraco in 1977 as technical services engineer. He knew nothing about tyres at that point – as his mining engineering studies did not cover them (most university and mining school courses still barely touch on tyre management) – so he once again started at the bottom, learning by work experience and mentoring from the company’s founder and its senior engineer. He also undertook a study trip to Japan visiting the head office and two factories from each of Bridgestone, Yokohama and Toyo – three of the major OTR tyre manufactures at the time. He tells IM that he is still learning. C Otraco experience worldwide Key events during his period with Otraco include starting and running the company’s first overseas operation at Rio Tinto’s Kelian gold mine in Indonesia in 1994; a two-and-a-half year stint in Chile managing the Escondida project and directing South American operations; and leading the project start-ups at Vale’s Carajas and Sossego mines in Brazil; and at Rio Tinto’s IOC operation in Canada. He also conducted the technical audit of Anglo American’s Mogalakwena tyre operation that eventually led to the company’s first onsite management contract in southern Africa. Cutler has done tyre consulting for mines in Australia, the US, Indonesia, Peru, Colombia, Argentina, Chile, Canada, Brazil, Ghana, South Africa and Botswana. He was involved in the development of tyre analysis techniques such as batching and axle fitment bias compensation and has led several investigations into tyre explosion events including 144 International Mining | SEPTEMBER 2016 the Radomiro Tomic fatality in 2000. Cutler has authored a number of technical and OTR tyre related papers, including two major reports on the status of the global OTR tyre market. The first, in 2004, predicted the crisis in mining tyre supply; an update followed in 2007. The OTR GLOBAL offering OTR GLOBAL is Cutler’s Perth based consultancy. It specialises in mining tyre management including selection, procurement, maintenance, operation, awareness and safety. Cutler states: “While the decade long OTR tyre supply crisis – which accompanied the China initiated boom in mining commodity prices – focussed the attention of mining companies on the importance of properly managing their tyres, there remain many opportunities for assisting companies to maximise the potential of their tyres, in particular longevity and productivity – and, importantly, to manage these processes safely.” Cutler says that there are still many misconceptions about and much poor understanding of mining tyre application, for example: n Being unaware that tyre maintenance of mine equipment is ten times more likely to result in a fatality than non-tyre maintenance of rubber tyred mining vehicles n Believing that hard (engineering) controls will compensate for inadequate tyre maintenance training and procedures or poor culture n Thinking that worn out tyres signify tyre life maximisation n Being reluctant to fit new tyres to the rear of haul trucks, unappreciative of the benefits this can deliver n Not understanding that poor roads result in haul truck damage costing several tim
