“Guiyang-Huangping Expressway Extension，The total length of the route is 8.305 kilometers，Adopt the standard construction of two-way eight-lane expressway，Subgrade width 39.5 meters。Long tunnels along the whole line 1017.5 meters/1 seat。Culverts are set along the whole line、There are 12 channels，The bridge is 2073 meters/Seven seats，They are all large and medium-sized bridges。”

Branch I of Guiyang-Huangping Expressway Extension Consortium Project，There is oneSTC250E5-The plug-in crane is in full swing.，Unlike other devices,，It doesn't have the sound of an engine roaring.，It is very quiet when working.。

Wang Bing, project manager of Guizhou Highway Group Seventh Engineering Co., Ltd., said.：“In the course of operation，The noise of the plug-in car is much less than that of the traditional fuel car.。But because the plug-in crane needs to be plugged in,，There are certain requirements for the power distribution of the construction site.。”

And that's why.，Many enterprises will have many concerns when choosing new energy equipment.：Whether the site is equipped with corresponding facilities，Whether it is convenient to use，Is electricity safe?。But in Wang Bing's eyes,，These worries are unnecessary.。

“Pre-construction period，The power distribution facilities of this construction site have not kept up.，We all use the fuel mode operation of the plug-in crane.。After all kinds of power facilities are improved in the later period，It is fully switched to power operation.。The original interval for repairing the bridge is 30-50 meters will be equipped with a power distribution cabinet.，Moreover, bridge construction is generally a fixed operation.，Ideal for use with plug-in crane。”

Work with electricity by using plug-in crane，It also has great advantages in undertaking projects.。Wang Bing introduced：“Generally, the construction site rents equipment on a monthly basis.，Fuel costs are also borne by them.。Others rent 28000 yuan./Month，Even if I mention 30000 yuan./Month，The construction side is also very willing.。Because in the short term,，The construction side saved a lot of money on oil.。In the long run，The project hardly needs to worry about environmental protection.。”

The first division of Guiyang-Huangping Expressway Extension Project is located in the secondary water source protection area.，Since the commencement of the project，Has been facing environmental inspection.。Wang Bing said：“The inspection has hardly stopped.，But we don't have this concern when we use plug-in cranes.，Because there are basically no emissions from plug-in operation。These plug-in cranes are performing very well.，So now the company has purchased two more for construction on another project.。”

Every new journey.，Someone always leads the way.。At present，From north to south，From the city to the country，From housing construction to road and bridge，More and more construction sites and hoisting enterprises choose new energy equipment.，In the realization”Double Carbon“On the way to the goal.，Realize green transformation step by step。
