March 28, 2023，Guided by the National Construction Machinery Quality Inspection and Testing Center，《Construction Machinery and Maintenance》Magazine sponsored，Undertaken by Craftsman Construction Machinery“2023 Development of Construction Machinery Products（Beijing）Forum and China Construction Machinery Product of the YearTOP50 Award Ceremony”Held ceremoniously in Beijing。Shandong Lingong has won many honors，AmongE6650HExcavator and Shandong LingongL956H EVSeparately picked by electric loader“2023TOP50 Gold Award for Technological Innovation”And“2023TOP50 Gold Award for Innovation of New Energy Products”。

Let's look at the first product first.。Shandong LingongE6650HFully Electronically Controlled Excavator Award，It is well deserved.。It stands out from many products.，Capture the heart of the judges at one stroke。

The organizer pointed out in the award speech.：Shandong LingongE6650HIs the only realization“Autonomous complete machine controller”+“Autonomous full-electric control main control valve”+“Autonomous complete machine control system”Fully electrically controlled domestic crawler hydraulic excavator，It is an innovative technology of domestic excavators.

New Paradigm。

To be specific，Shandong LingongE6650HExcavator 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 38~45L/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 demand，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 box 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、880LSuper large fuel tank and other designs，Save time and effort in construction。

The honor is an affirmation that Shandong Lingong always attaches great importance to product research and development.。Future，Shandong Lingong will continue to increase funds、Talent input，Research and development of high-end products、New energy product layout and other aspects of sustained efforts，Bring more quality products to customers，Create higher value for the industry。
