HEO Lubricants for Mining Operations
Powering performance in the world’s toughest environments.
Haul trucks, shovels and dozers running around the clock through dust, heat, rain and grade.
What the pit does to your oil.
Dust & contamination
Fine silica enters breathers, fill points and seals, accelerating abrasive wear in every compartment.
Heat & continuous load
High ambient temperatures and long duty cycles push oil temperatures up and shorten oil life.
Water ingress
Tropical rainfall, wash-down and wet pits introduce water into gear cases and greased joints.
Shock loading
Digging, loading and haul-road impacts put pins, bushings and final drives under shock loads.
Remote logistics
Remote sites need dependable supply, correct storage and simple product line-ups.
Availability pressure
Every unplanned stop on a haul truck affects the production plan for the whole pit.
Every unit, every compartment.

Lubrication is a reliability decision.
Component life on a haul truck is shaped by what enters the oil, how hot it runs and how long it stays in service. The right product is only one part; handling and monitoring complete the picture.
Keep it clean
Keep it cool
