CAT 349D2 is equipped with a Cat C13 engine, meeting the requirements of the US EPA Tier 2, EU Stage II, and China National Emission Standard 2. With a rated power of 301kW, when combined with a high-efficiency hydraulic system, it can maintain excellent performance even under low fuel consumption conditions. In the economy mode, compared with the previous model, the fuel consumption for moving the same amount of materials can be reduced by up to 9%, achieving a balance between power and energy conservation.
Efficient Hydraulic System
Its main pump has a maximum flow rate of 734L/min. The innovative design of the hydraulic interactive sensing system enables either of the two hydraulic pumps to fully utilize 100% of the engine power, significantly increasing the operating speed of the machine and the rotation efficiency of the pivot. The boom and stick regeneration circuits effectively recover energy, optimizing the cycle time and further enhancing fuel economy.
Outstanding Operational Performance
The CAT 349D2 stands out in its operational capabilities. The bucket breakout force reaches up to 267kN, and the stick breakout force is 201kN. With a swing speed of 8.7rpm, a travel speed of 4.5km/h, and a maximum drawbar pull of 338kN, its powerful parameter performance allows it to easily handle various complex engineering operations such as excavation, loading, and trenching.
Robust and Durable Structure
The equipment’s main frame is solid and reliable. The standard 9.0mt (9.9t) counterweight is firmly installed on the main frame with bolts, enhancing overall rigidity. The track idlers, carrier rollers, and track guides adopt sealed lubrication technology, effectively reducing wear and extending the service life, ensuring the long-term stable operation of the equipment.
Convenient Operation and Maintenance
The cab features a pressurized design with forced filtered ventilation, and the suspended seat supports flexible adjustment, providing a comfortable driving experience. The full-color LCD monitor supports information display in 28 languages, and the operation switches are reasonably arranged for easy control. At the same time, the maintenance points of the equipment are centrally set up, and components such as engine oil and oil filters are easy to maintain, effectively reducing maintenance costs and time.
