The HD22 series bulldozer incorporates advanced technologies such as centralized lubrication, centralized pressure monitoring, and automatic track tensioning. It can be equipped with various working attachments and operator cabs to adapt to diverse operational requirements. This equipment demonstrates ideal efficiency for earth-rock operations and large-scale material scraping tasks, making it a high-performance solution for heavy-duty construction projects.
Main Features:
• Cummins QSNT-C235 Engine
The Cummins QSNT-C235 engine delivers enhanced power and reliability, meeting demanding operational needs. It improves fuel efficiency compared to previous models, combining robust torque output with low fuel consumption to achieve superior overall fluid efficiency.
• Highly Reliable Powertrain
Features a stable torque converter, power-shift transmission, and a two-stage spur gear final drive for efficient power transfer, ensuring durability and smooth operation.
• Automated Diagnostics & Integrated Monitoring
Equipped with self-diagnostic systems and real-time monitoring. The cast-integrated instrument panel combines air conditioning, electrical controls, and instrumentation for a sleek, luxurious interface.
• Robust Full-Box Chassis Design
The mainframe adopts a full-box welded steel structure fused with the rear axle housing. This design offers exceptional impact resistance, bending/torsional strength, and high-quality welds to ensure lifelong structural integrity.
• Ergonomic Operator Interface
The ergonomically designed adjustable driver's seat and armrests, along with left-side placement of gearshift, steering, and throttle controls (featuring flexible shaft mechanisms), enhance comfort. Work-device controls on the right utilize a servomechanical system for lightweight, precise operation.
• High-Efficiency Blade & Ripper Configuration
Standard straight-blade design delivers formidable cutting force. Optional triple-shank ripper attachment excels in penetrating tough materials like clay and frozen soil, maximizing productivity and breakthrough power.
