Re-powering defers truck replacement

摘要

Coal & Allied has significantly extended the service life of its Dresser 830 rear dump truck fleet by replacing their original motors with Detroit Diesel Series 4000 units. Hunter Valley coal miner Coal & Allied, a subsidiary of Rio Tinto, has re-powered nine Dresser 830 rear dump trucks by replacing the original engines with Detroit Diesel Series 4000 units. The Dresser 830 units can carry a payload of 218t with an overall GVM of 377t and are part of a fleet of 52 similar vehicles. In a typical year the fleet moves an estimated 200Mt of overburden material at the operations near Singleton, NSW. According to Coal & Allied Hunter Valley Operations maintenance manager Dan Gray, an evaluation of whole-of-life costs by the company found a potential for substantial savings if the service life of each unit could be extended. This required the use of the latest engine technology, which in turn had various spin-off environmental and community benefits such as reduced exhaust emissions and lower operating noise.
