Construction Machinery Enters the Electric Age

Many people said

Range is the biggest concern.

Liugong 922FETrailer excavator

Cracking endurance anxiety，Continuous and efficient operation

 

Recently，Liugong Successfully Delivered 922 to Major Customers of Fujian Renewable ResourcesFEDrag the electric version of the excavator，This is the first time that Liugong has delivered towing construction machinery to customers.。922 delivered this timeFEElectric excavator will be used for scrap steel、Medium-term processing of renewable resources such as automobile dismantling。In addition，922FEThe towing electric excavator is also suitable for feeding at the material port.、Mining、Small-scale fixed-point construction conditions such as metal smelting。

922FEElectric excavator is a new product upgraded by Liugong on the basis of 22 tons of pure electric excavator.，Achieve 24 hours a dayhHomework。

 

01

Build an industry leader“Electric excavator”

 

“

As the earliest manufacturer of electric excavators in the construction machinery industry,，Engineer Liu not only has conventional electric equipment，It also strives to create subdivision.“The Green Army”，Uch as a tunnel version electric excavator、Miniature electric excavator、Dragging electric version, electric excavator, etc.，Lead the electric track。

Detailed analysis 922FEDrag the electric version of the excavator

922 delivered this timeFEDrag the electric version of the excavator，There are many differences between conventional electric excavators.。

1

An on-board rectification system specially developed for the towing version is added.，Class III insulation with vehicle regulation level、Overcurrent、Overload、Protection against surge, etc.，Compared with the modified products of non-vehicle regulation level on the market，Have complete protection against static electricity、Leakage，Better protection of personal safety and equipment safety。

2

At the same time, the high pressure system of the whole vehicle meets theIP67 degree of protection，Higher dustproof and waterproof performance；

3

It has stronger seismic performance，It is more in line with the working characteristics of large vibration of excavators.；

4

Using permanent magnet synchronous motor，Precise control of motor speed，Energy conversion efficiency up to 95%。

922FEOn the basis of energy saving and emission reduction, towing electric excavator，It not only improves the safety and comfort of operation,，And it works more efficiently.，Longer operation time，It is a small-scale fixed-point working condition.，A master of multi-shift work。

Not only that，Compared with the traditional internal combustion excavator，This 922FEIt is also more humane in terms of maintenance.：

1

In the working environment of indoor heavy dust，922FEHigh dustproof performance of permanent magnet synchronous motor selected for electric excavator，There is no problem of blockage of the matching filter element of the diesel engine.；

2

In terms of heat dissipation，The electronic fan of the whole vehicle has the function of forward and reverse rotation.，Fficient heat dissipation，But also can quickly remove dust.，Extend the cycle of radiator dust removal；

3

Zero emission for indoor work、No pollution、Low noise，Achieve safe and comfortable operation；

More importantly,，Compared with the internal combustion excavator with the same tonnage，922FELight can save about 150000 use costs per year.。Engineer Liu will continue to implement“Double Carbon”Policy，Insist on technological innovation、Contributing to the Construction of a Green and Beautiful Home！
