SDLG E6750HB Tunnel Crawler Excavator

1. Standardly equipped with well-known brand super-strong crawler tracks, which are wear-resistant, non-deformable and have a long service life under stone working conditions;

2. The chassis, key main beams of the upper rack, and key stress-bearing parts are designed to be thickened and strengthened, with strong load-bearing capacity. The overall structure of the boom is strengthened, and the bucket arm is thickened in many places to extend its lifespan and have good reliability;

3. Fully protective crawler guards effectively protect walking devices in mines;

4. The special-shaped high-strength steel structure of the cab, with a fully sealed design on the top and front of the cab, improves the sealing of the cab and effectively protects driver safety during mining construction;

5. Large-displacement dedicated power, professionally adjusted and matched by Lingong, the crushing is efficient and powerful, specializing in “hard bones”; high-pressure common rail ultra-high-pressure injection, optimized injection angle, good atomization, more complete combustion, saving fuel and consumption ; The engine and hydraulic system have been professionally matched and adjusted to achieve a balance of high efficiency and low fuel consumption in the low-speed working area;

6. One-click switching of single pump + double pump crushing mode, fuel-saving and efficient customer independent control, meeting the diversified needs of different working conditions;

Fully electronically controlled hydraulic system, the main valve integrates a proportional solenoid valve, and the wiring harness connection replaces the pilot line. The oil circuit is simpler, the pressure loss is small, and it is fuel-saving and efficient;

7. It adopts three-stage oil-water separation filtration and sensor early warning to better adapt to various domestic quality diesel oils; the oil-water separation operation is simple and can be operated conveniently by the driver, effectively improving the durability of the engine;

8. Extra large radiator and variable oil dispersion system can adjust the oil output according to the oil temperature to achieve precise control and more energy saving; the system has small internal leakage and longer-lasting continuous operation capability. The oil dissipation fan can rotate forward and reverse to dissipate heat and remove dust;

9. The hydraulic oil tank is equipped with double oil return filter elements, with a large filtering area, small impact on the filter screen by the return oil, long maintenance intervals, and high reliability of the hydraulic system;

10. DC air filter system, suitable for medium to heavy dust conditions. Direct-flow air intake, small air intake resistance, saving fuel;

11. The filter element is made of nanomaterials, which has high filtration efficiency and effectively prevents premature engine wear;

12. Standard LCD color touch screen, two-way operation of buttons and touch screen, good selectivity;

13. Through the display screen, you can perform intelligent operations such as forward and reverse rotation of the job variable cooling fan, one-click switching between forward and reverse;

14. The right pilot console integrates multi-level switches such as page turning, throttle, high and low speed, and maximum power, which are within easy reach and easy to control.
