Mobilgrease XHP™ 681 Mine helps Colombian mining company extend equipment life*

Situation

A Colombian mining company operates a Liebherr R9350 excavator, lubricated with Mobilgrease XHP™ 681 Mine grease to extend the life of the equipment and its components. Formulated with an advanced lithium complex technology, Mobilgrease XHP™ 681 Mine grease is specifically engineered to handle the lubrication demands of mining equipment. In an effort to maximize the benefits achievable with Mobilgrease XHP™ 681 Mine grease, the company approached ExxonMobil engineers for a strategy to prevent unscheduled downtime and further enhance the productivity of its equipment.

Recommendation

ExxonMobil engineers recommended supplementing the use of Mobilgrease XHP™ 681 Mine grease with a preventive maintenance program to monitor and adjust the lubrication systems on the excavator blades. They also urged maintenance personnel to pay close attention to the operating temperatures of the critical points on the excavator joints.

Result

Together, Mobilgrease XHP™ 681 Mine grease and the company’s commitment to preventive maintenance have enabled a number of substantial performance benefits. By lubricating the excavator joints with Mobilgrease XHP™ 681 Mine grease, maintenance personnel successfully extended their lifespan by 86%, surpassed 114,800 in-service hours on the pin and bushing components, and generated a company-estimated annual savings of US $118,670.
