220hp Tracked Bulldozer

TD22T-5 BULLDOZER

The Zhonggong Hantang bulldozer is equipped with the Chongqing Cummins NT855-C280S10 engine, showcasing exceptional high power, efficiency, and energy-saving characteristics. The high-efficiency turbocharger it is configured with not only broadens and strengthens the engine's efficient operating range but also reduces fuel consumption by 12-21g/kW·H, significantly improving fuel economy and saving users more operating costs.

The advanced lubrication system meticulously cares for each component of the engine, ensuring their stable operation under complex conditions of constant oil temperature, low oil pressure, and variable flow. This system greatly reduces the engine's friction power, effectively extending the engine's service life, and laying a solid foundation for the Zhonggong Hantang bulldozer's long-term stable operation, enabling it to efficiently complete various tasks. The engine's cylinder block and cylinder head use high-strength materials combined with a new structural design, making operation more reliable and energy-efficient, achieving full combustion even under harsh conditions of high speed and heavy load, thereby reducing emissions and aligning with current environmental protection concepts.

In terms of the drive system, the Zhonggong Hantang bulldozer uses a reliable gear shifting transmission device, a performance-stable hydraulic torque converter, and a secondary straight-tooth final drive, ensuring strong and efficient power output. The power shift planetary gear transmission is compact and reasonable, with a smooth and stable meshing process and extremely high transmission efficiency, capable of accurately transmitting power. The YJ409B type hydraulic torque converter has a diameter of 409mm and an efficiency of up to 0.87. Its structure is simple, belonging to the single-stage, single-phase, three-element type, with a wide efficient speed range, easily adapting to different work scenes and operational needs.

The chassis system of the Zhonggong Hantang bulldozer uses a semi-rigid suspension walking system, ensuring that the track rollers and tracks maintain good contact, effectively expanding the contact area between the tracks and the ground, significantly improving the bulldozer's traction. This allows it to operate stably in various complex terrains such as muddy, rugged, and steep slope environments, demonstrating strong passability. The strength main pin track is specially developed and designed for harsh working conditions, with high reliability and strong load-bearing capacity, easily coping with various complex working conditions.

The cooling system is crucial for the stable operation of the Zhonggong Hantang bulldozer, ensuring that the engine can operate normally and reliably under any load or thermal condition, effectively preventing engine overheating, and ensuring the engine's performance remains stable. Whether in high-temperature heat or high-intensity working environments, the cooling system can play an excellent heat dissipation role, ensuring the stable operation of the equipment.

The electrical system is a prominent highlight of the Zhonggong Hantang bulldozer, with automatic diagnosis and full-process monitoring functions. The injection instrument panel cleverly integrates air conditioning, electrical appliances, and instruments, not only beautiful and high-end in appearance but also convenient to operate, allowing operators to accurately grasp the equipment status in real-time, timely discover and solve potential problems.

The driving environment of the Zhonggong Hantang bulldozer is very superior, with a driving cabin that is not only beautiful and generous in appearance but also has a spacious interior and broad vision. The damping device can effectively absorb vibrations, providing operators with higher safety and comfort, reducing fatigue from long-term operation. Designed according to ergonomics, the driver's seat and handle can be easily adjusted up, down, forward, and backward to meet the body needs of different operators. Speed control, steering wheel, and throttle are set on the left, using cable operation, with comfortable operation feel; the working equipment is on the right, using a servo control system, achieving flexibility in the operation process, greatly reducing operator fatigue.

The box-type main frame of the Zhonggong Hantang bulldozer is made of high-quality materials and high-strength castings, with excellent impact load resistance and torsional force. High-quality welds ensure that the main body can work normally and stably throughout its life cycle, sturdy and durable, fearless of various harsh working environments.

The working parts and attachments of the Zhonggong Hantang bulldozer are rich and diverse. The standard straight blade, with high cutting force, high-strength structure, and high-performance materials, has excellent durability, able to adapt to all harsh environments, easily coping with various high-intensity operations. The 6.4m³ large-capacity blade is suitable for various earthwork and bulk material operations, with extremely high operational efficiency. In addition, there are angle blades, U-shaped blades, semi-U-shaped blades, and other types for users to choose from, fully meeting different operational needs. The large single-tooth ripper's penetration angle can be flexibly adjusted, suitable for loose clay, frozen soil, and other soil layers, as well as stripping gravel, hardened salt mines, and other solid surfaces. The strong beam, frame, tempered tooth bar, tooth tip, and other components ensure work efficiency and super penetration, able to efficiently complete various complex operational tasks.

In terms of safety, the Zhonggong Hantang bulldozer is equipped with safety warning lights, reverse alarms, horns, a high-performance braking system, and unique painting, effectively protecting the safety of surrounding personnel and enhancing all-weather operation safety. Seat belts, handles, and safety signs provide comprehensive safety protection for operators, ensuring the personal safety of operators during operation. Side guard plates can effectively protect the engine and radiator, preventing them from clogging and damage due to foreign particles, while also making the overall appearance more beautiful. Standard antifreeze can increase the cylinder's boiling point, lower the cylinder's freezing point, effectively prevent scale deposition on the engine and radiator, and benefit the engine's cooling and protection. In addition, a moving bar for garbage and other items can be optionally equipped, providing additional protection for the operator in emergencies.

The Zhonggong Hantang bulldozer is also very convenient in maintenance. Eye-catching signs can accurately indicate the machine's maintenance time, facilitating users to timely arrange maintenance. The equipped battery is maintenance-free, reducing maintenance workload. The open engine cover design allows internal components to be exposed as much as possible, facilitating inspection and maintenance. Due to the product's high reliability, the mean time between failures (MTBF) is long, making maintenance costs much lower than other similar products. Zhonggong Hantang's comprehensive service network provides timely, thoughtful, and enthusiastic services, allowing users to use the Zhonggong Hantang bulldozer with confidence, fully meeting users' expectations for Zhonggong Hantang products.
