Guanzhuang – Xinhua Expressway Project（Guanxin Expressway for short）YesG59 An important part of Hubei Expressway，It's the country“The 13th Five-Year Plan”One of the 165 major engineering projects，It is also a key national poverty alleviation project.。It is planned to open to traffic by the end of 2023.。

”

The first contract section of Guanxin Expressway，Many solid piers are ready to pour capping beams.。4 SANY plug-in cranes along the hillside，Be arranged in a patchwork manner one by one，Or lift the rebar，Or hoisting the mold。Four devices work at the same time, but they are very quiet.，Even the sound of birds in the sky can be heard clearly from time to time.。

“This construction site is basically equipped with electric boxes.，Position the equipment，Plug in the cable and you're good to go.，Very convenient。From the actual use of the process，Fixed machine position auxiliary pouring operation in road and bridge project，Plug-in cranes have a lot of advantages.。”Tang Jiang, Minister of Machinery Department of Guanxin Expressway Project, was very interested in talking about these plug-in cranes.。

“The environmental protection department often inspects the construction site.，Although the machinery and equipment we use at present are in line with national standards.，But the plug-in crane is a new energy product.，It is green construction visible to the naked eye。Not only less carbon dioxide emissions，The noise is also much less.，Households only a dozen meters away from the working face，Watching TV at home is not affected at all.。”

Tang Jiang's statement has been obtained.STC250E5-1（Plug in）Confirmation of operator Li Liang：“There is no difference between the operation of the equipment and the fuel vehicle.，The performance is not inferior at all.，But the sound is much lower during the construction.。Have to say the difference.，The biggest difference is that it is more fuel-efficient.。”

Mr. Wu, general manager of Shimen Zhigao Construction Machinery Leasing Co., Ltd., said.：“Two of the four plug-in cranes areSTC250E5-1，The other two are.STC250E5-2。So far，The cumulative electricity consumption of these four equipment is more than 9000 degrees.，This is equivalent to saving about 50,000 yuan in fuel costs.。”

“In addition to reducing fuel consumption，Using electricity can also reduce the engine.、Wear and consumption of regeneration system，The cost of maintenance can also save a lot.。On the one hand, it can reduce costs.，On the other hand, it can also respond to the national call to reduce carbon emissions.，Protect the environment，Kill many birds with one stone，Why not?？”

At“Double Carbon”Under the guidance of the goal，“Green”It is an unavoidable subject in the hoisting industry.。Mr. Wu said：“We went to many construction sites to inspect.，It is also seen that more and more new energy equipment has joined the construction team.。Dry hoisting，Not only to ensure the quality of the project、Construction safety，We can't destroy the local natural environment.。They put the project in our hands.，We have to live up to this trust.。”
