SDLG 6.6t-E660FL Small Compact Crawler Excavator with flexible operation
E660FL belongs to Shandong Lingong 6T multi-working condition, small excavator, which is an upgraded version of E660F. It integrates energy saving, reliability and comfort, flexible operation and low noise. It is widely used in construction sites, municipal construction, farmland renovation, garden engineering, pipeline laying and other working conditions.
The whole machine has compact structure, flexible maneuverability, good adaptability to working conditions, fast action speed and high work efficiency;
Original Japanese Yanmar engine: four-valve structure, large air intake, full combustion, low energy consumption; with automatic idling function, energy saving and noise reduction.
Load sensing hydraulic pressure: The main control valve can be operated unrelated to the load, and the coordination of action is not affected by the load. It is related to the angle of the pilot handle. Different actuators can be finely controlled, with good maneuverability and high work efficiency.
Three-stage filtration, two-stage oil-water separator and one-stage fine filtration have high efficiency, good oil adaptability and more durable engine.
Shelf: Integral reinforced shelf structure, compact structure, good rigidity, uniform load distribution, small deformation, and high reliability.
Lower frame: Reinforced design, verified by high-strength, heavy-load fatigue test, the lower frame has high strength and large bearing capacity.
The ground clearance is large, and the trapezoidal beam opening can prevent soil damage to the chassis.
The high-strength rotary platform has strong impact resistance; the material of the rotary gear ring is good and more wear-resistant.
Equipped with mature four-wheel belt, it has large bearing capacity, wear resistance and high reliability.
The boom cylinder and the bulldozer cylinder are equipped with protective plates.
Intake multi-stage filtration: The main filter element further filters the air entering the engine, and the safety filter element serves as its backing, which plays a protective role in the case of the main filter element failure.
Effectively prevent the engine from premature wear and prolong the service life of the engine.
Wide field of vision: Fully toughened front windshield, equipped with skylights, spacious and bright, with a wider field of vision;
The front windshield can be easily slid to the top. When digging a deep trench, the driver can stand up and take a look at the probe for better vision.
The left rear corner is curved glass, and the rear vision is wider.
The sound-absorbing sponge is attached to the inside of the engine cover to reduce noise and make operation comfortable. The outdoor noise is only 97 decibels, far below the industry standard.
Control system: eye-catching color monitor to monitor the running status of the machine at any time; convenient pilot handle and control switch, easily accessible and easy to operate.
