Enables reliable mobility for mining-site uneven ground or construction-site heavy-load transportation—to avoid operational inefficiencies.
- Rigorous quality: Undergoes 28+ strict tests—torque durability (6,500+ travel cycles without performance loss), high-low temperature cycles (-30°C to 100°C, 1,200+ cycles), wear resistance (3,500+ working hours), and impact resistance (950N impact without structural damage). Withstands dusty construction/mining environments, mechanical vibration, and heavy-load travel without gear wear or seal failure.
- Professional support: Backed by a dedicated team with deep expertise in Doosan 400LC/420LC drive systems. Offers 7×24 online assistance, including step-by-step installation guides (mounting torque charts, alignment verification methods), maintenance recommendations (lubrication intervals, gear inspection tips), and troubleshooting for slow travel or abnormal noise. Average response time <2 hours.
- Cost-effective reliability: Delivers Doosan OEM-level transmission performance at a competitive price. High-strength alloy gears and wear-resistant bearings extend service life by 72% vs. generic reduction gears, reducing long-term replacement costs by 43%.
