TISCO Mining Co. Ltd.’s Jianshan iron mine introduced 35 sets of BELAZ dumpers with hydraulic sumps of about 200 liters and carrying capacities of up to 130 tons. Using a conventional hydraulic oil, the dumpers experienced high operating temperatures averaging 100°C (212°F) during the summer, which caused unscheduled downtime to occur as a result of heating. In an effort to improve equipment productivity, the mine approached ExxonMobil to identify a lubricant solution that could help reduce operating temperatures. 

ExxonMobil engineers recommended TISCO Mining Co. Ltd. switch to Mobil DTE 10 Excel™ 46 hydraulic oil for the hydraulic system of the dumpers. Formulated with high viscosity index base oils and an additive system that provides excellent frictional properties, Mobil DTE 10 Excel™ 46 oil also provides outstanding oxidation and thermal stability in severe service hydraulic systems. 

After transitioning to Mobil DTE 10 Excel™ 46 hydraulic oil, the company reported that operating temperatures in the dumpers were reduced to 60°C (140°F). The switch has also helped reduce unscheduled downtime and increase mine output, generating a company-estimated savings of US $823,746.
