Recently，Independently developed by SunwardSWE750ELRHydraulic excavator with extended arm successfully delivered off the production line。Under the blue sky and sunshine，SWE750ELRStand proudly，Its working arm stretches out into the sky like a dragon.，It seems to show its majesty and power to everyone.。This excavator is specially developed for an open-pit coal mine in China.，It is mainly used for mine slope repair and treatment and long-distance deep pit safety coal extraction.，According to local construction characteristics，Multiple customized multi-functional configurations are added.，More suitable for local construction conditions。In addition，The device is in Sunward Intelligence.“Mine sharp weapon”SWE750FDevelop and design on the basic platform of.，Adopt the complete set of original electro-hydraulic system，Mature and reliable，Work stability。

So

What are the main new special features and configurations?？

1

Working device adopts 12m+9mExtended Boom and Stick，Optional 1.6-2.0m³Heavy-bucket reinforce type wear-resistant bucket，The maximum excavation height exceeds 17 meters.，The maximum excavation distance is 21 meters.，Meet the excavation operation of high and remote distances。

2

Equipped with lithium battery，Compare with that conventional lead-acid battery，High storage capacity，Long charging cycle life，On this basis, the fuel system is equipped with a cold start device.，It has the preheating function of burning diesel oil.，It can meet the regional low temperature conditions.（-45℃）Normal startup of，Better adaptability in alpine regions。

3

Complete set of automatic fire extinguishing system，Including automatic fire extinguisher and 4 manual fire extinguishers that can identify smoke and temperature in the engine compartment，Can effectively extinguish a fire when the fire breaks out，Prevent the fire from spreading，Protect the safety of excavators and operators。

4

Equipped with security camera system，The whole car is equipped with multiple high-definition cameras.，Used to monitor the blind area of excavation operation at any time，So that operators can more accurately grasp the environmental conditions around the excavator.。In addition，The camera can also transmit image information.，Help the operator to better understand the construction site，So that that operation efficiency and quality are improve。

5

Equipped with centralized automatic lubrication device，16LHigh capacity lubrication pump，Meet the long cycle of greasing time，Boom、Articulation pins of the arm and cylinder are automatically lubricated，In order to reduce the customer's oil time.，Improve work efficiency。The centralized lubrication system also has a lubrication system pressure monitoring function.，The lubrication system is blocked、Faults such as open circuit of pipeline can be prompted by instrument alarm.。

6

Used for the getting-off device“HDLC”Intensified 100tClass Chassis System，Lengthen and widen，Unilateral upgrade to 9 reinforced roller，It is equipped with heavy-duty double-rib track shoes.，Strong grip ability，The stability is better，It is more suitable for long-arm working conditions.。

7

Adopt the high strength independently developed by Sunward、Anti-roll cab，ThroughFOPS/ROPSSafety standard certification，On the top and front windshield、The lower part is equipped with protective net as standard，Strengthen protection，To meet the requirements of mine construction and crushing、Safety requirements for scarification operations。

Other than that，SWE750ELRBut also with more ergonomic design.，Equipped with full vehicle armrest and maintenance platform，More space for staff maintenance and operation；Cooling system fan with reverse self-cleaning function，Maintenance and cleaning are more worry-free；Adopt the first self-cleaning air filter in China，Regular automatic dedusting through its own dedusting pump，Extend the filter replacement cycle，So that that air intake cleanness of the engine is improve……All in all，SWE750ELRIt is a mining expert with excellent performance.。

The project is in the early stage of development.，Because the product delivery time is urgent.，And the product configuration is also difficult.，It brings great challenges to the project team.，But the team still withstood the pressure.，Work overtime，Finally, the R & D and production delivery were successfully completed.。

SWE750ELRTracked hydraulic excavator rolled off the production line successfully，It is not only another successful case of customized design and development of Shanhe Intelligent Large Excavator，It is also another typical interpretation of the independent innovation brand of Shanhe Intelligence.。

Future，Sunward Intelligence focuses on the research and development of traditional excavators.，It will also persist in innovation.，Develop and improve special equipment suitable for various operating conditions.，Serve customers with special needs，Create greater value for customers。
