Heavy industry
China’s heavy‑industry machinery sector boasts an annual market size exceeding RMB 6 trillion, accounting for more than 40% of the global market and firmly establishing itself as a key pillar of the global industrial value chain. Against the backdrop of industrial upgrading and the transition to green, intelligent manufacturing, ensuring the long‑term, reliable operation of equipment has become a core competitive advantage. For over two decades, Derunbao has been deeply engaged in the field of lubrication for heavy‑industry machinery, delivering specialized lubrication solutions that enhance equipment availability, reduce life‑cycle costs, and help China’s heavy‑industry sector advance toward high‑quality development.
Lubricating greases for heavy‑duty machinery are the lifeblood of reliable equipment operation. Their applications span critical components such as pin joints in work devices, slewing bearings, track‑drive systems, gearbox gears, boom bearings on concrete pump trucks, wheel hub bearings on mining trucks, and hydraulic breakers. These greases must endure extreme operating conditions—severe impact under heavy loads, low‑speed oscillation, intrusion of mud and sand, a wide temperature range (from frigid −30°C to high‑temperature friction), and continuous outdoor service—placing exceptionally high demands on extreme‑pressure and anti‑wear performance, water resistance, shock resistance, adhesion, pumpability, and corrosion protection. Any lubrication failure can lead to abnormal wear of pin joints, seizure of slewing bearings, track fractures, gearbox burnout, or even complete machine breakdown, resulting in repair costs running into hundreds of thousands of yuan and delays in project schedules—issues that are particularly acute in continuous‑operation environments such as mines, infrastructure projects, and ports.
