driven by the concepts of haze control and energy conservation and environmental protection, the production and sales of various new energy vehicles have accelerated. As the world's largest construction machinery market, China's production giants such as excavators and loaders have also led enterprises into the "green era"

"last May, we successfully developed the world's first LNG excavator. Now, the products of all electric hydraulic excavator and LNG excavator 5) do not contain impurities that promote the accelerated decomposition of resin. The prototype of hybrid excavator has been manufactured, and it will be mass produced in the second half of this year." In a recent interview, Ni Lin, deputy general manager of Shanda reconstruction Machinery Co., Ltd., said

with the increase of market demand for LNG, the layout of LNG filling stations of the three major oil majors in Shandong has also accelerated. "If the enterprise has a truck using LNG every day, and the daily gas consumption is more than 2 tons, we can consider building a separate LNG filling station for the enterprise." On August 8, sunyongzhong, deputy general manager of Jinan Kunlun Energy Co., Ltd., told the herald that the company has now established LNG filling stations for two enterprises in Jinan. With the increasing use of new energy vehicles, they plan to conduct fixed cooperation with logistics enterprises

lng excavators save energy by 30%

the frequent haze some time ago has made cars the culprit. Industry experts said that diesel vehicle exhaust is the largest "contributor" to PM2.5. The nitrogen oxides emitted by diesel vehicles nationwide are close to 70% of the total vehicle emissions, and PM is more than 90%; The CO and HC emissions of gasoline vehicles are higher, more than 70% of the total emissions

among diesel vehicles, construction machinery is a major fuel consumer. According to Ni Lin, 50 ton mining excavators consume l diesel oil in an hour, and even 20 ton excavators consume 20L diesel oil per hour. High energy consumption and large emissions are the characteristics of fuel engineering machinery

"LNG excavators only emit carbon dioxide and water, and do not emit nitrogen oxides. At the same time, when the operation efficiency is equivalent to that of fuel excavator, the use cost is 70% of diesel, and the energy saving is 30% Ni Lin said

it is understood that with the high oil price, new energy engineering machinery is favored by more and more manufacturers. In addition to the mountain reconstruction machine, our aviation load-bearing support project is a good example. Many loader manufacturers such as Gonggong, Liugong and Doushan have also launched energy-saving products based on LNG loaders. Among them, XCMG's LNG wheel loaders have been produced and sold in batches

according to Zhang Yi, deputy director of the technical management department of the mountain reconstruction machine, compared with LNG excavators, all electric hydraulic excavators are more energy-saving. He said that the all electric hydraulic excavator of the mountain reconstruction machine has been used in China. Zero emission, low noise and energy saving are its outstanding advantages. The operating cost of this excavator is 50% less than that of fuel excavator. However, due to the high power of the excavator and the waste of time in charging, the excavator is suitable for places with power supply, such as ports, tunnels, mines and cities

in Ni Lin's view, the basic maintenance of new energy engineering machinery is also an important factor in the low cost of use. Fuel engineering machinery needs regular maintenance, and each maintenance cost is expensive. New energy engineering machinery does not have oil change, machine filter, lubricating oil, etc

LNG filling stations can be built for enterprises

although the use cost is low, the lack of LNG filling stations restricts the promotion of new energy engineering machinery

however, this obstacle is expected to be gradually eliminated. Hanxiaoqing, an energy analyst at axense Xiwang, told on the 9th that the number of LNG filling stations in China reached 640 last year, including 140 in Shandong. During the "12th Five Year Plan" period, Kunlun Energy Co., Ltd. plans to build 720 LNG filling stations in Shandong, which is the largest number of provinces and cities in China. Some private enterprises are also actively involved in the construction of LNG filling stations

in addition to building LNG filling stations on major transportation roads, Kunlun Energy Co., Ltd. also builds special LNG filling stations for enterprises. Sunyongzhong guide newspaper said that at present, there are two LNG filling stations in Jinan for enterprises to supply gas to Jinan Bus Corporation and Shandong transportation group

sunyongzhong frankly said that there is no special gas filling service for construction machinery vehicles. "First, the number of LNG construction machinery vehicles is small; second, the use of construction machinery is phased. When a project is completed, it will be transferred to other places. Unless the large-scale project construction reaches fourorfive years, it is usually not cost-effective to build a station." However, he also stressed that if such vehicles reach a certain number, mobile gas filling services can be considered. At the same time, if an enterprise uses more than 2 tons of vehicles per day, it can also establish a separate LNG filling station for the enterprise

sun Yongzhong told the herald that in addition to these two enterprises, the main customers are some logistics heavy trucks, but these logistics vehicles are retail investors and are not fixed. In the next step, we plan to achieve fixed cooperation with logistics enterprises

"at the same time, the customer company usually needs to provide a suitable site for internal use when building a gas station." Sunyongzhong explained that compared with the externally listed gas stations, this is less restricted in terms of policy and will be more convenient

according to Ni Lin, he has done research in Inner Mongolia. Since LNG heavy trucks are widely used in mines, PetroChina and Sinopec have established LNG filling stations for some large mines. He predicted that this model would be popularized in more places

financial subsidies to be introduced

there is no doubt that new energy will become the development direction of construction machinery

"although the use cost is low, the price is about 15% higher than that of fuel vehicles. If there are state subsidies, users must choose LNG excavators." Ni Lin said frankly that although the new energy engineering machinery conforms to the national energy conservation and environmental protection policy, there is no financial subsidy, which has a great impact on its sales

Ni Lin said that due to subsidies, LNG heavy trucks have become a new growth point in the heavy truck market in the past two years, and LNG buses have become more and more popular. However, the sales of new energy engineering machinery still needs users to calculate long-term accounts. For example, LNG excavator is 15% more expensive than fuel excavator. Due to its low cost, the price difference can be recovered in about a year and a half. Jinan is hard and tough: an enterprise with a large modulus of elasticity has ordered five LNG excavators. With the LNG heavy truck of the enterprise, it can establish its own LNG filling station. But there are not many enterprises like this now

"from the perspective of haze control, energy conservation and environmental protection, new energy engineering machinery is a product that should be encouraged to buy and should be included in the subsidy catalogue of new energy vehicles." Ni Lin believes

his suggestion may come true soon. Miao Wei, Minister of the Ministry of industry and information technology, said in an interview with the media on the afternoon of August 8 that greater support should be given to new energy vehicles and energy-saving vehicles. "Whoever has a good effect in energy conservation and emission reduction will be given more subsidies." Miao Wei revealed that the Ministry of industry and information technology is formulating preferential policies for enterprises specializing in the production of energy-saving vehicles and new energy vehicles, and strive to introduce them in the first half of the year
