According to the Ministry of Foreign Affairs, at the China-Tibet "Rim of the Himalayas" International Cooperation Forum that opened early this month, Chinese Foreign Minister Wang Yi met with Afghan Interim Government Acting Foreign Minister Mottaki. The two sides discussed matters such as carrying out counter-terrorism cooperation in Afghanistan, integrating Afghanistan into the "Belt and Road" initiative, strengthening economic cooperation between the two countries, and assisting Afghanistan in integrating into regional economic cooperation. Information revealed by the Afghan side after the talks showed that the Afghan interim government is focused on opening the Wakhan Corridor and strengthening economic exchanges between China and Afghanistan. There are rumors from the outside that the Afghan interim government hopes to build a road in the Wakhan Corridor to directly open a land channel from Afghanistan to China and ensure that Afghan products can be transported to China more conveniently. At the same moment, there was another piece of news. Recently, it is said that the Afghan interim government sent people to visit Iran. The focus of the visit was to extend the railway line from Khaf, Iran, to the western Afghan city of Herat, which will be completed and opened to traffic in 2022. There are rumors from the outside that the Afghan interim government hopes to use Iranian investment to further extend the railway, that is, to complete the second phase of the railway from Herat to Kabul. In the future, it hopes to build the southern part of the Pamir Plateau and into Wakhan Corridor, building railways to China. In July this year, Afghanistan, Uzbekistan and Pakistan jointly signed an agreement to build a trans-Afghan railway. The trans-Afghan railway in the agreement is expected to start from Termez, a city in southern Uzbekistan, to Mazar-i-Sharif, a city in northern Afghanistan, cross the Hindu Kush Mountains, pass through Kabul and Jalalabad, and proceed along the Kabul River Valley. Finally, it was connected to the Pakistan railway network in Peshawar. It seems that the Afghan Taliban interim government plans to carry out large-scale infrastructure construction in the territory. From a geographical point of view, it is actually located in the western part of the Pamir Plateau. The majestic Hindu Kush Mountains traverse the east and west wings of Afghanistan. The east is connected to Taxkorgan County in southern Xinjiang by the Wakhan Corridor, and the west extends to The low-lying Herat, an important town in western Afghanistan, and the Hari River flow through Herat and form the boundary river between Afghanistan and Iran, before turning north and flowing into Central Asia. On both sides of the Hindu Kush Mountains, low-lying plain deserts are formed on the northern and southern flanks of Afghanistan, such as the Karakum Desert and the Tochar Basin extending from the Transoxiana region of Central Asia in the north, and the Hull Basin in the south. The lowlands formed by the Mandeb River, the Suleiman Mountains separated from Pakistan, and the important southern Afghan town of Kandahar located on the upper reaches of the Helmand River. This makes Afghanistan's geographical factors show the geographical characteristics of being high in the center, west, south, relatively low in the north, and higher in the east than in the west. Therefore, the two strategic railways currently planned to be built by the Afghan government can almost connect multiple geographical units in Afghanistan. For example, from Mazar-i-Sharif as the northern core to Kabul, and from Herat as the western core to Kabul, these are all conducive to Kabul's central government strengthening its control over these surrounding strategic towns. Communicate geographical units and strengthen centralization. In the next step, if the Afghan government can use railways to connect Kunduz, Kandahar, etc., this situation will be strengthened. At the same time, this will further enhance the Afghan government's ability to mobilize national resources. After all, railway is the most efficient mode of transportation for land-based countries, with the lowest transportation cost, largest transportation volume, and the most cost-effective transportation method. Its overall transportation capacity is far better than relying solely on road transportation. Even though the United States has occupied Afghanistan for 20 years, road construction in Afghanistan has always been in a relatively backward state. Moreover, there are many tribes in various regions, and roadblocks have not been eliminated. This is a fatal problem for a unified Afghanistan of. The construction of railways will greatly improve the Afghan government's ability to conduct foreign trade and mobilize national resources. For example, public sources mentioned that the railway built from Herat to Khaf has a weekly transportation capacity of tens of thousands of tons. For Afghanistan, This is extremely valuable transport capacity, which far exceeds road transport capacity given the insufficient number of heavy-duty vehicles in Afghanistan. Therefore, for Afghanistan, the construction of railways not only has the characteristics of connecting relatively independent geographical units, but will also further strengthen the logistics capabilities of the Afghan government and facilitate the development of the national and regional economies.

The base is positioned as a regional manufacturing center, logistics center and talent center. The project investment is 300 million rand and is expected to be completed in one year. By then, it will be able to produce 1,000 excavators and other engineering machinery and equipment annually. "Sany South Africa Headquarters Base" project foundation laid Sany has been operating in South Africa since 2005. In 2023, Sany South Africa's sales are expected to reach 800 million yuan. In the eighteen years since it entered the South African market, SANY has participated in the construction of almost all major local infrastructure projects. In 2013, 60 SANY equipment participated in the entire construction of Kusile Power Plant, Africa's largest thermal power plant project in South Africa. Among them, Sany's 750-ton and 630-ton crawler cranes stand out from many international brands and undertake the most critical hoisting work of thermal power stations. They also set a new record for China's domestic cranes exported to Africa. SANY crawler crane is used for construction at Kusile Thermal Power Plant In 2018, it was also in Johannesburg, South Africa, that President Xi Jinping proposed "building a new BRICS partnership for the industrial revolution" at the 10th BRICS leaders' meeting. SANY's steady development in South Africa and the new launch of "SANY South Africa Headquarters Base" have added a new footnote to this major initiative. On the occasion of the fifth anniversary of the proposal of the "BRICS New Industrial Revolution Partnership", on November 17, Xiang Wenbo, rotating chairman of Sany Group and vice chairman of the BRICS Innovation Base Industrial Innovation Alliance, attended the first BRICS Innovation Base Entrepreneurs It was stated at the forum that as the world's leading Chinese construction machinery manufacturer, SANY Group actively practices and participates in the game, deeply participating in the major historical process of BRICS cooperation, and regards BRICS countries as a history that cannot be missed in the development of SANY. opportunity. Deeply involved in BRICS cooperation and achieved fruitful results in industrial development The concept of "BRICS" was first proposed in the international community in 2001, and the story of Sany Group and BRICS began in the following year. In 2002, SANY started its globalization journey. Among the first batch of products sold overseas, 4 motor graders were exported to India. SANY took the first step of corporate globalization in the BRIC market. Having been deeply involved in the local area for many years, SANY India has now occupied a considerable market share in the local industry in multiple vertical product fields such as excavators, cranes, pile drivers, mining machines, road and port machinery. SANY has invested more than 750 million rupees in its localized manufacturing plant in Pune, India. As SANY India celebrates its 20th anniversary, it has successfully achieved the milestone of selling over 22,000 devices. In Brazil, another BRIC country thousands of miles away, SANY's Brazilian subsidiary was registered in 2007 and began investing in expanding marketing and manufacturing operations in 2010. In July 2014, President Xi Jinping personally witnessed the signing ceremony of the Sany Investment Brazil project after attending the sixth BRICS leaders’ meeting in Brazil. Over the past ten years, SANY has invested nearly US$100 million in Brazil. SANY Investment Brazil Project Signing Ceremony Cross mountains and seas to seek development. Xiang Wenbo said that currently, in order to seize the opportunities of the new era and new technological revolution, Sany is fully implementing the globalization, digital intelligence and low-carbon transformation strategies. Among them, globalization ranks first, urgent and important. The BRICS countries are important engines of the global economy. SANY has been deeply involved in BRICS cooperation for many years and has achieved fruitful results in industrial development. The latest data shows that in the markets of Brazil, Russia, India, South Africa and the six countries that have just been invited to join the BRICS family in 2023, Sany Group has achieved cumulative sales of more than 70 billion yuan. Among them, 14,500 units of equipment will be sold in 2022, with sales exceeding 13 billion yuan. In the first three quarters of 2023, sales exceeded 14 billion yuan, accounting for approximately 40% of Sany Group's overall overseas sales in the current period. Open, inclusive and win-win cooperation helps local social development In July 2014, China first mentioned the eight-character spirit of BRICS cooperation: openness, inclusiveness, cooperation and win-win. As a construction machinery company, SANY Group not only actively invests in BRICS countries, but also gives full play to its industry advantages, using an open and inclusive attitude to deeply support local economic and social construction and enhance win-win cooperation. The Adama Phase II wind power project in Ethiopia is the first foreign wind power project to adopt Chinese standards and technology. It is also an important measure taken by the Ethiopian government to protect the ecological environment and meet economic and social development. The total installed capacity of the project is 153MW, and the average annual power generation is about 500 million kilowatts. The project, from wind turbine hoisting to wind farm construction, is all completed with SANY equipment. The project meets about 30% of the electricity demand in Addis Ababa, the capital of Ethiopia, and has injected new impetus into Ethiopia's economic development. It has been highly praised by the local government and the international community. Adama Phase II Wind Power Project In 2017, Saudi Arabia announced that it would build an unprecedented "future city" called NEOM. As the core project of the "Saudi Vision 2030", NEOM covers an area of 26,500 square kilometers and is a large-scale comprehensive urban construction project involving a large number of infrastructure and construction projects. Since the second half of 2021, more than 1,600 units of SANY equipment have been deployed at the NEOM New City construction site, including cranes, excavators, loaders, dump trucks, concrete pump trucks and other types of construction machinery. Currently, these equipment are in use with 50 local SANY units. Many engineers are working together with their iron arms and sweat to promote the rise of a giant future city at full speed. NEOM new town construction site At the Burj Khalifa in Dubai, United Arab Emirates, Sany ultra-high pressure tow pumps set the world's highest pumping record; at the world's tallest "Statue of Unity" in India, Sany crane equipment completed 80% of the lifting projects; at the World Cup in Brazil With the Olympic venues, hundreds of SANY excavators, cranes, and graders participated in the entire construction process; in the central business district of Egypt's new capital, more than 30 SANY equipment helped realize the Egyptian national rejuvenation plan... In the past more than 20 years During the years, the "China Red" figure of SANY equipment can be seen everywhere in the BRICS countries. SANY pump truck is constructing the Burj Khalifa, the world's tallest building in the United Arab Emirates Deeply cultivate cultural exchanges and water the tree of friendship and cooperation "The relationship between countries lies in the mutual friendship between the people. Only through deep cultivation and deep cultivation can the tree of friendship and cooperation flourish." As a corporate citizen, while SANY has achieved rapid development and mutual benefits in BRICS cooperation, it has also never forgotten its social responsibilities, deeply cultivated cultural exchanges with local people, and watered the tree of friendship and cooperation. Taking root in the South African market for eighteen years, SANY has been deeply integrated into the local social development in South Africa. "Teach a man to fish", also "teach a man to fish". In 2021, combined with the actual situation of local society, SANY South Africa launched the "Empower Women in Mining" social welfare activity to provide unemployed women in remote areas with a week-long closed excavator operation training. After the training, the trainees successfully became certified operators hand. This event has aroused enthusiastic and positive responses from South African government departments, local media and all walks of life, and they have all praised its outstanding contribution to women's rights and social welfare. “Empower Women in Mining” During its more than 20 years in India, SANY has also participated in cultural exchanges between the two countries in various forms. In May 2018, Trinity Institute of Technology and Somaiya University of India signed a cooperative education agreement in Mumbai, India, to cooperate closely in areas such as exchange student course credit exchange, orientation class training, student summer overseas internships, and teacher exchange visits. Sany Group became the first Chinese-funded enterprise to establish an educational cooperation project with an Indian institution of higher learning. At the end of 2018, the first batch of Somaiya students went to Trinity Institute of Technology for one month of exchange study. Since 2018, nearly 150 Somaiya teachers and students have gone to SANY India for exchange and study. Industry, academia and research have achieved in-depth cross-field cooperation, bringing closer the "people-to-people affinity" between China and India. The first batch of Somaiya students went to Trinity Institute of Technology for exchange studies "Those who share the same ambition should not let the mountains and seas be far away." In August 2023, the 15th BRICS leaders’ meeting announced that Saudi Arabia, Egypt, the United Arab Emirates, Argentina, Iran, and Ethiopia would be invited to officially become members of the BRICS family. Walking together on the road, heading towards the future together. BRICS cooperation has broad prospects and future development is promising. SANY will seize the historical opportunity and share resources, wisdom and opportunities through the BRICS Innovation Base Industrial Innovation Alliance to build the "Second Gold" of the BRICS countries. The cooperation vision of "Ten Years" has become a reality and Sany has made contributions!

The excavator is an important engineering machinery equipment and is widely used in earthmoving engineering, building construction, mining and other fields. In recent years, the excavator market has continued to develop, and various types of excavators have continued to emerge. Among them, the excavator amphibious chassis has become an innovative technology that has attracted much attention, providing a new solution for the excavator's operating range and efficiency. The excavator amphibious chassis is an excavator chassis with amphibious operation capabilities. The chassis design of traditional excavators is designed for land operations and is not qualified for operations in water or muddy areas. Excavators designed with an amphibious chassis have the ability to switch working modes on land and in water, so they can also perform tasks smoothly in rivers, lakes, swamps and other water environments. The design principle of the excavator amphibious chassis is mainly based on buoyancy and driving force. It adopts special structure and sealing technology to ensure that there is sufficient buoyancy inside the chassis to support the floating and smooth movement of the entire fuselage in the water. The bottom of the chassis is equipped with a buoyancy plate or buoyancy tank, and the amount of water in and out is controlled through a pump system to adjust the buoyancy and sinking degree of the fuselage. At the same time, the amphibious chassis is also equipped with a powerful hydraulic drive system, which can achieve forward, backward and steering in the water by driving crawlers or propellers. The advantage of the excavator amphibious chassis is that it expands the scope of application of the excavator and improves work efficiency and flexibility. It can handle water conservancy projects, underwater pipeline repairs, dam repairs and other water construction tasks, avoiding the traditional problem of using additional boats or building pontoons and other auxiliary equipment. At the same time, traditional excavators often get into trouble when operating in muddy areas, and the mechanical feet of the amphibious chassis can provide better support and stability, avoiding the risk of getting stuck. However, there are some challenges and limitations associated with excavator amphibious chassis. Amphibious chassis are more expensive to design and manufacture due to the complexity of operating in water and the need for additional watertightness and buoyancy control systems. At the same time, the working environment in the water also places higher requirements on the design and operation of excavators, requiring operators to have relevant skills and experience. Despite this, the innovative technology of the excavator amphibious chassis has still attracted widespread attention in the engineering construction field. With the continuous advancement of technology and market demand, we have reason to believe that the excavator amphibious chassis will continue to develop and grow in the future, bringing more convenience and benefits to the engineering construction field.

Xihoumen Road-Railway Bridge Stayed less than half a year Be the first to complete the task of drilling eight 6.3-meter large-diameter main piers Construction efficiency is far ahead! The main pier foundation of the bridge uses a total of 18 6.3-meter super-large diameter bored piles, which is currently the largest diameter bored pile foundation in China. The piles are 106 meters deep, the water depth is 66 meters, and they penetrate 40 meters into the rock. Some pile foundations are as deep as 116 meters. The XCMG XR1600E rotary drilling rig needs to pass through complex formations such as highly weathered granite, weakly weathered crushed granite, cataclastic rock, slightly weathered crushed rhyolite, and lay the foundation for the bridge deep under the sea. Rock drilled by XR1600E rotary drilling rig The construction platform where the XCMG XR1600E rotary drilling rig is located has relatively hard ground, and the seafloor stratum is inclined rock. The project team used a hob-type drill bit to expand the hole in four stages to ensure the verticality of the pile foundation. It broke the conventional graded hole expansion process and reduced the number of classifications. It took the lead in adopting the four-stage hole expansion process of 2 meters, 3 meters, 4.5 meters, and 6.3 meters, breaking through the 1.8-meter step difference in graded hole expansion. XCMG's XR1600E rotary drilling rig completes one pile in an average of 10 days. It is almost fully on duty and completes the project department's 8 pile construction tasks with high quality. This is a challenge between machines and nature, and it is also a battleground for equipment in the same industry. According to on-site construction data feedback, XCMG equipment efficiency is nearly 15% ahead, and it is the first to complete the tasks assigned by the project department.
