Construction Machinery Industry

Severe Contamination (Dust, Mud, and Gravel): Abrasive particles are common in construction sites and mines. Fine mineral sands and soil dust mix with lubricating grease, causing wear on bearings, gears, and pins. Particulate contamination accounts for approximately 80% of wear and over 50% of bearing failures throughout the machine's lifespan. Harsh environments often damage seals, leading to contaminant ingress and lubricant leakage.

-Heavy machinery such as crushers, loaders, and mining trucks are subjected to continuous physical stress. Intense vibrations and repeated heavy impact loads can damage the protective lubricating oil film, leading to catastrophic metal-to-metal contact friction wear. These machines typically operate at high speeds for extended periods, requiring lubricating oils with excellent shear stability to maintain their protective properties under sustained stress.

Equipment must operate normally in both frigid Arctic environments and scorching summer temperatures. Excessively high temperatures thin the lubricating oil, reducing its load-bearing capacity and causing it to evaporate or sinter into hard carbon deposits.
At extremely low temperatures, lubricants thicken, making pumping difficult and preventing them from quickly reaching critical components during initial startup. High temperatures combined with internal friction accelerate lubricant oxidation, producing corrosive acids, sludge, and varnish.

Maintenance risks: Manually lubricating large mining equipment is extremely dangerous for technicians. Many mines now use automated lubrication systems (ALS) to reduce human risk and ensure consistent lubricant usage.
