Recently, the offline ceremony of the country's first electric intelligent excavator SWE240FED independently developed by Sunward Intelligent was held in Sunward Industrial City. This equipment uses batteries instead of fuel and motors instead of engines, achieving zero emissions, low noise, and full autonomy for domestic engineering machinery. It is a truly green and environmentally friendly equipment.

He Qinghua, chairman of Sunward Intelligent, told a reporter from Securities Daily: "The outside world generally believes that we are just a construction machinery company. Our construction machinery, underground engineering, aviation, and new energy materials businesses are all We are aiming for one goal, which is to help the whole society achieve the carbon peak goal as soon as possible. Engineering machinery can help green construction and green mines, underground engineering can help green transportation, aviation emission reduction gives green wings to flight, and new energy anode projects. Put into operation to promote the green energy industry. The above-mentioned diversified businesses are integrated into thousands of projects for carbon emission reduction in the whole society, which can contribute a lot to the realization of the carbon peak goal of the whole society."

"Green" machinery. Green Construction

As early as 2018, the SWE25E pure electric mini excavator produced by Sunward Intelligent went to the capital Beijing to implement subway construction. Under the circumstances of closed space, small working area and poor ventilation environment, it took on Excavation, crushing, bulldozing, grabbing, drilling, ditch cleaning and other various tasks not only reduced the number of workers by 50%, saved nearly 50% of construction costs, but also improved work efficiency by 50%.

Wang Jian, Secretary of the Board of Directors of Sunward Intelligent, told a reporter from Securities Daily: "The pure electric micro excavator SWE25E became famous in the first battle and later received orders from multiple construction units. Some people once believed that micro excavators can achieve Purely electric, but large excavators also need diesel engines as power. The electric smart excavator SWE240FED we delivered off the production line proves from various technical indicators that large excavators can also be fully electric and even more intelligent.

It is reported that the electric intelligent excavator SWE240FED can be applied to urban areas and surface cold areas with high requirements on exhaust emissions and noise. , plateau sites with large temperature differences and insufficient oxygen supply, and construction sites in relatively confined spaces underground and in tunnels. After installing the remote control intelligent module, it has the characteristics of long remote control distance, safety and efficiency. With the help of intelligent technology, electric smart excavators are more suitable for operations in places with harsh working conditions and greater threats to human health and life, such as demolition, road clearance, debris cleaning and other operations in hazardous and explosive environments. Emergency rescue and other work. Since this year, infrastructure builders and mining developers from the Inner Mongolia Autonomous Region, Xinjiang Uygur Autonomous Region and other places have come to consult and negotiate.

Wang Jian told a reporter from Securities Daily: "From our test data, the SWE240FED electric smart excavator can work continuously for more than 6 hours after being fully charged. Using dual-gun charging, it can be fully charged from 5 It only takes 1.5 hours. It can be charged at night using low-priced electricity to complete work tasks during the day, which can also save customers comprehensive costs and directly generate economic benefits."

Two major industries support green travel

In green travel, the subway has been strongly promoted due to its convenient transportation and obvious carbon emission reduction effect. The China Railway Sunward Shield Machine under Sunward Intelligence has repeatedly made new contributions to the construction of subways in many places. At the end of March, China Railway Shanhe No. 3 shield machine, a subsidiary of Sunward Intelligent, successfully completed the construction tasks between Hedong East Station and Nanshi Road Station of Guangzhou Metro Line 11, and moved to the underground comprehensive pipe gallery project in the central urban area of ??Guangzhou. Wang Jian introduced the relevant situation to a reporter from Securities Daily: "The geological conditions in the south are complex, with underground rivers, caves, fault zones, aquifers, etc., which bring technical difficulties to shield machine construction.

Taking the Henan section of Guangzhou Metro Line 11 as an example, during the construction task of about 1,482 meters, our No. 3 shield machine successively overcame long-distance small curve excavation, segment floating, screw machine gushing, river bottom tool change, and Construction difficulties such as crossing the Pearl River and bypassing cultural relics have won unanimous praise from the project side. ”

Sunward Intelligent not only opened up a green corridor underground, but also opened up a green corridor for aviation. Put on green wings. Since this year, Sunward Technology, a subsidiary of Sunward Intelligence, has delivered multiple SA60L (hereinafter referred to as: Arola) aircraft. Technology and hardware have been continuously upgraded, and it is now in its third generation. The aircraft delivered this time is made of all carbon fiber composite materials, weighs only 348 kilograms, and has a maximum flight altitude of about 4,500 meters. Depending on the configuration, the price of an Arora ranges from 1.15 million yuan to 1.8 million yuan. The latest version of Arora only uses 95-octane gasoline, the same as that used in cars. With 120 liters of gasoline, Arora can fly 1,300 kilometers and consumes only 8 liters of fuel per 100 kilometers. Compared with aviation gasoline, it not only has lower use and maintenance costs, but also has fewer overall emissions. Now, our Arora orders have been scheduled until mid-July. After years of technology accumulation, our brand effect has been continuously amplified. The market share of domestic light sport aircraft has reached about 70%, ranking first in the market. In 2021, our goal is to achieve a production capacity of 100 aircraft and an output value exceeding 100 million yuan. ”

New anode technology helps green energy industry

Sunward Intelligent not only vigorously promotes carbon emission reduction in the fields of construction machinery, underground engineering, and aviation, but also invests heavily in the field of new energy anode materials. Carry out the construction of new processes and new projects. At the end of March, Sunward Intelligent signed the "Guizhou Dalong Annual Production of 100,000 Ton Anode Materials and Graphite Ultra-High Purification Application Project Investment Contract" with the Guizhou Dalong Economic Development Zone Management Committee.

The project covers a total area of ??800 acres, and is mainly used to build an annual production line for anode materials and graphite ultra-high purification production lines and related supporting facilities. The project is constructed in two phases, with an investment of 2 billion yuan in the first phase and a land area of ??400 acres. Build an anode material production line with an annual output of 50,000 tons; the second phase investment is 3 billion yuan, covering a land area of ??400 acres, mainly building an anode material and graphite ultra-high purification production line with an annual output of 50,000 tons. After the project is fully completed and put into operation, the annual output value is estimated to be 30. 100 million to 4 billion yuan
