The CAT D6R bulldozer, with its powerful engine, comfortable operation and convenient maintenance features, is widely used in various operation scenarios such as mining, construction and earthwork engineering. It is an excellent choice for the medium-sized bulldozer market.
1. Power System
Equipped with Cat C9 ACERT engine, with a rated power ranging from 130 to 176 kW. It adopts ACERT technology, maintaining engine performance while reducing emissions, and complies with Tier 2/Stage II and Tier 3/Stage IIIA emission standards. The engine is properly matched with the torque converter, and is equipped with three power control modes for heavy load, medium load, and light load. Users can choose according to the working conditions to achieve a balance between work efficiency and fuel consumption.
2. Hydraulic System
The system adopts a load-sensing hydraulic design, which can automatically adjust according to the operating environment. It only provides the hydraulic flow required by the machinery, achieving higher fuel efficiency. The dual-pump hydraulic system means that both the shovel response and steering performance can be simultaneously considered, resulting in better accuracy and maneuverability. This is particularly useful when performing operations in narrow areas or land clearing tasks.
3. Differential Steering System
By adopting the differential steering system, the speed of one track can be reduced while the speed of the other track can be increased. Even when the bucket is fully loaded, it can still provide excellent steering performance. The single-stage torque distributor transmits 70% of the engine torque through the torque converter, and the remaining 30% is transmitted through the planetary gear set. Thus, more power can be applied to the ground.
4. Structural Design
The front and rear frames adopt a plate structure. The overall center of gravity is well distributed, with a long wheelbase design and increased counterweight, resulting in good stability during operation. The large arm, small arm, and walking motor brackets are all reinforced with thick metal plates to meet the requirements of harsh working conditions such as quarries and construction sites. The high-pole sprocket design ensures that the final drive is not affected by ground impacts.
5. Operational Comfort
The cab adopts the D-series design and is equipped with a 14-outlet air conditioning control system. The ergonomic seats can be adjusted in multiple directions. It is equipped with a rearview camera and LED lighting. An optional panoramic camera system is available to provide a 360° bird's-eye view. The cab has a wide field of vision, excellent sound insulation and sealing performance, and good vibration reduction effect.
6. Maintain convenience
The lubrication points are centrally arranged, equipped with practical components such as anti-slip plates, which speeds up the maintenance process. Key components are easy to disassemble and replace, reducing downtime. The electrical connectors adopt a waterproof standard exceeding 6K9K protection level, ensuring the normal operation of the electrical system even in humid environments.
