Features
High-Power Engine for Extreme Working Conditions

Powered by the Cummins NTA855-C360S10 engine with 257kW output, the TC320 delivers strong torque reserve and excellent fuel efficiency for heavy-duty earthmoving operations. Equipped with an exhaust turbocharger, the engine maintains reliable power performance even at high altitudes up to 4,300 meters, ensuring stable productivity in challenging environments.

Built for Continuous Heavy-Duty Operation

Designed with independent engine cooling water tanks, chassis oil coolers, and integrated water-to-air cooling systems, the TC320 provides excellent heat management under demanding working conditions. The advanced cooling design improves component durability, simplifies maintenance, and supports long hours of uninterrupted operation.

Rugged Structure for Tough Job Sites

The TC320 adopts a full box-section main frame made from high-performance materials and high-strength cast components. This robust structure provides excellent resistance to impact loads, bending, and torsional stress, allowing the machine to perform reliably in harsh working environments throughout its service life.

Superior Undercarriage Performance and Ground Control

Featuring a low-mounted final drive system and an advanced crawler undercarriage, the TC320 delivers strong driving force, excellent climbing ability, and outstanding load-bearing performance. The 560mm wide tracks provide improved stability and adaptability across complex terrains, including mines, construction sites, and large-scale earthmoving projects.

Powerful Mining Bulldozer Performance with Blade and Ripper Attachments

Equipped with a straight-tilt blade and optional single-shank or three-shank ripper, the TC320 delivers powerful cutting and ripping performance for mining and heavy earthmoving applications. It can handle clay, frozen soil, gravel, and hardened surfaces such as salt mining areas.

Operator-Focused Design for Efficient Control

The TC320 combines reliable mechanical performance with practical maintenance features, including durable components, easy-access service points, and proven hydraulic systems with Weichai pumps, valves, and Wending cylinders. These features help improve machine availability and reduce downtime during demanding operations.
