Core Product Highlights

High-efficiency power system with fuel optimization

The machine is equipped with a high-performance electronically controlled engine that provides strong power reserves while maintaining operational efficiency. This ensures stable output during continuous heavy-duty work and helps reduce overall maintenance requirements.

Reliable transmission system with optimized matching

The transmission system is independently manufactured and field-tested for long-term reliability. It is precisely matched with the engine power curve, ensuring smooth power delivery, high transmission efficiency, and stable operation under varying workloads.

Operator comfort and intelligent control system

The hexagonal cab design offers a spacious interior and a wide field of vision. Optional FOPS/ROPS protection enhances safety in complex environments. The integrated intelligent display system, combined with heating and cooling air conditioning and electronically controlled throttle, provides precise and comfortable operation.

Strong terrain adaptability and flexible configuration

The chassis system is designed with a long ground contact structure and high ground clearance, improving stability and off-road capability. The DT22 Construction Bulldozer supports multiple blade options, including straight tilt, U-type, angle, and rock blades, as well as rippers and auxiliary lighting systems to meet different working conditions.

Easy maintenance and service efficiency

Key structural components inherit proven design standards from mature product lines. The electrical system is well-protected, and the large hinged side covers allow convenient access for inspection and maintenance, reducing downtime and improving service efficiency.
