Engine:
The Cummins QSM11 engine is reliable, efficient, low fuel consumption, meets Euro 3 emission standards, has excellent performance, is energy-saving and environmentally friendly, and is easy to maintain.
Hydraulic system:
Original imported hydraulic components, electrically controlled dual pump full power crossover+negative flow control system, hydraulic pilot proportional control, stable and reliable quality, high work efficiency, energy-saving and consumption reduction, and large excavation force;
Equipped with electrical control system:
Dot matrix multifunctional large screen color LCD display, capable of real-time monitoring of machine operation status, with fault self diagnosis and recording functions, electronic throttle control, always considering fuel economy, ensuring maximum efficiency of the entire machine when operating in various work sites. Provide multiple operating modes for users to choose from, meeting different working conditions;
Enhanced working device:
The strengthened design of the working device is more suitable for harsh working environments such as mines and quarries. The rotary platform adopts a new type of high-strength and high stability, and the frame edge beam edge plate angle steel is strengthened. The key parts of the chassis are increased in strength, improving their service life. It has a wide rail gauge and a long track grounding length.
This 47.6-ton large hydraulic excavator is designed for mining, large earthwork projects, port loading and unloading, and major infrastructure construction. In mining scenarios, its 290kN bucket digging force and 11L large-displacement engine can efficiently crush hard rocks; in earthwork projects, the maximum digging depth of 7.8 meters and the 2.5m³ large-capacity bucket meet the needs of deep foundation pits and high slope operations; the dual-speed travel system and 35° climbing ability ensure that the equipment can operate stably in complex terrains such as muddy and steep slopes. In addition, the 350L hydraulic oil tank and 650L fuel tank support long-term continuous operation, making it a high-productivity core equipment for large-scale engineering projects.
