High-quality 22-ton HUANGGONG TY220 Crawler Bulldozer is suitable for road construction

This retired HUANGGONG 220 bulldozer from a state-owned institution, commissioned in 2014, has logged only 1,000+ operational hours due to its role as a backup training unit and emergency response asset within the organization, sparing it from high-intensity workloads. Preserved with near-new condition, its unmodified original configuration, intact tracks, and crisp engine sound reflect meticulous maintenance. The versatile large blade adapts flexibly for curved earth grading or straight pushing, paired with a rear-mounted ripper to tackle diverse terrains effortlessly. A decade of rigorous state-sector upkeep ensures enduring power and reliability, with every component embodying unwavering commitment to quality. 

In the secondhand construction machinery market, I’ve watched competitors slash prices to unbelievably low levels to grab orders. Their bulldozers look shiny on the surface, but hidden beneath cosmetic refurbishments are cracks and chronic flaws. Buyers take them home excitedly, only to face frequent breakdowns within months, with repair costs eventually surpassing the price of a new machine. We refuse to play that game. From day one of our business, we’ve believed that real value lies in a machine’s bones , its durability and reliability. Every used bulldozer we sell is personally inspected to ensure it can withstand the harshest job site conditions. Yes, our prices might not be the cheapest, but when clients finish their projects without endless downtime and repair headaches, they realize: Quality is the ultimate cost-saver

Daily Maintenance

1. Engine oil, hydraulic oil, coolant, and fuel level checks

 Inspect levels and replenish to standard if insufficient; observe for leakage traces.

Clean dust from air filter elements (require shift-based cleaning in dusty environments); check diesel filter water sedimentation and drain.

Adjust track tension to specified value (excessive looseness/tightness accelerates wear); remove rocks and mud between track plates; inspect lubrication status of idler wheels and carrier rollers.  

4. Structural components and safety devices  

Tighten blade and ripper connection bolts; check brake system and steering control sensitivity; ensure lights, horn, and fire extinguisher are functional.
