9.1tons Ultra-Large Excavator SDLG Lingong E6950h With 6.2m³ Bucket For Mining Machinery

Product Advantages

High power, energy saving and consumption reduction

563kW engine with sufficient power reserve; transfer case, low speed, high torque, low fuel consumption and high efficiency.

No aftertreatment system, no DEF required, reduced use costs.

Fully electro-hydraulic system, high fuel efficiency

The main valve integrates the proportional solenoid valve to achieve fully electrical control. The wire harness connection replaces the pilot pipeline, making the fuel circuit simpler and reducing pressure loss.

Dual independent electronically-controlled main pumps and large-diameter main valves are used to achieve the best matching of power and hydraulic pressure, fully exert the performance of the machine, and improve operating efficiency.

Boom cylinder regeneration + arm cylinder large chamber oil inlet and return + bucket valve external confluence, etc. bring higher speed, smaller system pressure, and higher operating efficiency of working devices.

Intelligent temperature control, longer operating time

The extra large radiator and oil cooler are used to realize low power consumption and higher level of energy conservation, and maintain the best operating oil temperature.

The variable displacement piston cooling pump/cooling motor can adjust the oil output according to the oil temperature to achieve precise control, energy conservation and noise reduction.

The cooling fan can rotate forward and reverse for both heat dissipation and dust removal.
