Course Overview Power Transmission components are vital elements in a rotating machinery system and require the same attention to detail as bearings and seals to achieve optimum life. Aspects of power transmission reliability include inspection, monitoring, correct assembly, and system optimisation to achieve maximum life. This course shows the way to assemble and maintain power transmission components: belts, chains, and couplings.

Operator Asset Care is considered an integral element of a plant's Total Plant Reliability strategy. This training course will teach the machine operator to perform day to day tasks of basic maintenance and fault finding, such that the operator can help prevent and/or predict potential problems, addressing them before they can impact production. And by doing so, decrease downtime and increase plant productivity.
