Mine exclusive，Comprehensive omnipotence

Shandong LingongE6650HThe fourth national excavator

The protagonist introduced today is a「Mine sharp weapon」——Shandong LingongE6650HExcavator。This is a high-performance excavator specially designed for comprehensive mine construction.，Whether it's ore stripping.、Ore crushing or platform loading，All have excellent performance.。

 Powerful，Energy saving and high efficiency

Speaking of mine construction.，I have to mention its power.。E6650HThe excavator is equipped with Cummins 12LEngine，8% increase in power over previous generation%，More power、Work more efficiently；Engine and hydraulic system are professionally matched、Top tuning，The best balance between high efficiency and low fuel consumption can be achieved in the low speed working area.。

Fully electrically controlled hydraulic，Precise and fuel-efficient

E6650HEquipped with 280ccLarge displacement main pump，Move faster，More efficient；The main valve adopts the integrated proportional solenoid valve independently developed by Lingong.，Achieve full electrical control；Independent control of each action of the whole machine，Intelligent confluence，Faster response。Such a hydraulic system configuration，Make the action of mine operation more accurate，The stability of the hydraulic system is also better。

The data shows，In earthwork stripping and mine loading conditions，9-The fuel consumption of the 10th gear is about 40~45L/h，At the same efficiencyE6650HFuel consumption is 15% lower than the previous generation%Above。

 Variable oil dispersion，Energy-saving and pressure-resistant

High-intensity construction can not avoid the problem of heat dissipation，E6650HThe hydraulic oil heat pump is upgraded to a variable pump.，The oil supply can be adjusted according to the oil temperature，The oil does not have to withstand high pressure all the time.，Not only energy saving and environmental protection，The service life can also be greatly prolonged.；Optimized design of heat dissipation system based on heat dissipation flow field analysis，Have a large heat dissipation area、Oil temperature is low、Mall system internal leakage and the like.，Compared with the previous generation of products, the water heat dissipation capacity is improved by 15%，Oil heat dissipation capacity increased by 20%，Continuous operation capability is more durable。The cooling fan also has the function of forward and reverse rotation.，Heat dissipation、Dust removal is both correct.。

 Heavy-duty design，Solid and reliable

Heavy-duty designE6650HBe called“Tough guy in the mines.”，Because it uses reinforced working equipment and chassis.，The structural parts are welded by robot.，Welds are tested by flaw detector.。Customized structural member sheet，The bearing capacity is large，Longer life。There is also a fabricated chassis，Large grounding area，More stable and durable heavy-duty operation！

Comfortable driving，Care for the operator

Of course, mine construction should be good to the operator.，E6650HAdoptedHIt is a new cab，The configuration is unambiguous.。It features an automotive-grade immersive cabin with heated seats、Intelligent air conditioning、Big skylight、Cold and warm storage boxes and other luxury hardware，There is also an 8-inch LCD smart display.、KeypadConfiguration such as integrated operation，Bring the control experience within reach for the operator。

 

Human nature design，Save time and effort

Mine construction is most concerned with efficiency.，E6650HHumanized maintenance，Uch as a nano air filter、Automatic lubrication、880LLarge fuel tank and so on.，Save time and effort in construction。

 

Efficient、Save fuel、Cozy、Save time and effort，

If you are in need of a comprehensive operation of outstanding strength.

65-ton mining excavator，

E6650HI'm sure I'll be your right-hand man.！
