SDLG Excavator E6400f 40t Digger Excavator Excavator Machinery 2.2cbm Bucket

The energy-saving and efficiency features of this machine are at the forefront of its design, making it a powerful and economical choice for heavy-duty operations. It is powered by a 13L electronic fuel injection engine with a large displacement, produced by Volvo specifically for Lingong. This engine offers impressive power while operating at a low speed of revolution, which enhances its dynamic properties and ensures low fuel consumption. A standout feature is the automatic idle function: if the guide handle remains inactive for 5 seconds (default setting), the engine automatically reduces to idle speed. This not only conserves energy but also reduces noise, contributing to the prolonged service life of the engine.

The hydraulic system further enhances efficiency by incorporating an independent motor-driven fan for heat dissipation. The fan's speed is automatically adjusted based on the machine's cooling needs, resulting in better heat dissipation and longer operational duration. This intelligent system ensures that the machine can maintain peak performance even during extended periods of heavy use.

Reliability and durability are built into every aspect of this excavator. The oil-bath air filter ensures more complete filtration, providing safer air supply to the engine, which is particularly important in harsh mining environments. This design choice minimizes the early-wear failure rate, making the engine one of the most reliable in the industry. Additionally, the machine features a three-level oil filter with a large filtration area and high accuracy, further safeguarding the engine during operation.

Comfort and environmental protection are also key priorities. The excavator is equipped with a standard skylight, an optional rear camera, and a color LED monitor, providing an unobstructed view and allowing operators to control the machine's status with ease. The negative flow hydraulic system, finely tuned by VOLVO, is perfectly matched with the engine to ensure smooth and harmonious compound control actions, providing a comfortable and responsive handling experience.

Maintenance has been made convenient and efficient with the inclusion of modern features. The driving cab is equipped with a computer remote diagnostic interface and an external power source interface. When connected to a diagnostic program (TECHTOOL), the system can self-inspect for faults, simplifying the maintenance process. Furthermore, the fan pulley is designed to expand and tighten automatically, reducing downtime and making routine maintenance quicker and easier.
