460HP Hydraulic Bulldozer
Power System:The Cummins KTA19-C525 turbocharged diesel engine delivers powerful, efficient, and energy-saving performance. Its integrated cylinder block and head design minimize the risk of water and oil leakage. Compared to similar products, it features 25% fewer parts, significantly reducing the failure rate and lowering maintenance costs, which saves over 50% in maintenance time.
Transmission System:The power shift gearbox and planetary final drive ensure efficient power transmission, high durability, and elevated production efficiency. The system optimizes fuel economy according to external load changes. Hydraulic components absorb impact loads, extending engine life by 1.5 to 2 times. The gearbox utilizes a multi-disc clutch, hydraulic combination, and forced lubrication, while the central transmission employs spiral bevel gears with splash lubrication.
Hydraulic Working System:The upgraded oil cylinder design features imported seals and hoses, enhancing service life and reliability. An external working valve simplifies maintenance.
Electrical System:Imported instruments provide accurate, intuitive data display and enable electronic monitoring of critical parameters like oil temperature, oil level, and water temperature, ensuring high reliability.

This dozer excels in earthwork mining and rock stripping, making it ideal for construction projects and other demanding environments. Its advanced structure allows it to handle challenging tasks effectively, ensuring optimal performance and durability.
Structure
The full-box structure main frame is made of high-performance materials and high-strength castings, enhancing its ability to bear impact loads and resist bending and torsion. This design supports continuous high-strength operation in harsh conditions, while quality welds extend the frame's lifecycle.
Chassis System
The K suspension floating driving system and pivot chassis structure reduce impact loads on the transmission, improving traction performance and vehicle longevity. An advanced shock absorption system stabilizes the vehicle under complex working conditions. The main sealed and lubricated crawler belt allows for convenient assembly and disassembly.
Driving Environment
The cab offers a stylish design with ample space and a wide field of vision. An installed shock absorber minimizes vibration, and the air conditioning system enhances operator comfort and safety. The instrument panel features an integrated layout for electrical components, instruments, and air conditioning. Ergonomic adjustments for the driver's seat and armrest improve usability, while a PPC pilot control system makes operation more flexible, reducing fatigue.
Work Tool Accessories
The front working device includes a standard semi-U-shaped shovel blade made of high-strength materials, providing strong cutting force and durability for various tasks. A 16m³ super-capacity shovel is ideal for earthwork and bulk material handling. The rear device is a single tooth scarifier with an adjustable angle, offering high penetration and strength.
Security
Safety features include warning lights, a reversing alarm, and horn, enhancing safety for surrounding personnel. Design elements like seat belts, handrails, and safety signs offer operator protection. The side shield protects the engine and radiator from external debris. Standard antifreeze raises boiling points and lowers freezing points, enhancing engine cooling and protection. Optionally, an anti-overturning frame can be installed for added safety.
Maintenance
Clear signs guide correct maintenance practices, and the maintenance-free battery simplifies upkeep. An open hood provides easy access to internal components for inspection. The engine's high reliability results in lower maintenance costs compared to competitors. Platinum's service network offers timely, supportive service, ensuring a worry-free equipment experience that meets expectations.
