Recently, Changsha Metro Line 2 was opened, and like all Changsha citizens who are looking forward to more convenient travel, Huang Wang can't wait to experience the feeling of taking the new subway, "Taking the subway is not only money-saving, economical and environmentally friendly, but also saves time." ”

Huang Wang is a service engineer at Sany Crane's Xiangjiang Branch, and has personally participated in the construction of Changsha Metro Line 2. For more than two years, Huang Wang has been in close contact with Sany Crane every day, and in his eyes, these equipment have long been as precious as his children, and the glory that these equipment has brought to him has also made him extremely proud.

Subway construction has strict requirements for the stability, lifting height and safety of lifting equipment, and any slight negligence may cause accidental work-related injuries. The main task of Sany Crane at the construction site is to accurately put the underground diaphragm wall steel structure woven by workers into the ground, and the diaphragm wall forms a solid steel support and support system to prevent safety accidents such as collapse.

"Don't underestimate this job, the underground construction site is narrow, the working conditions are bad, the crane boom, the bracket can not be fully extended, to accurately put these behemoths into the ground, and between the wall, between the wall and the ledge must be tightly seamed is not an easy job to complete." Huang Wang said that every engineer and operator here has been carefully selected, not only requiring high technology, but also boldness, carefulness, composure and stability.

In order to ensure the smooth progress of the subway construction, Sany Crane Xiangjiang Branch will select the best technical and professional service engineers to form a service team to escort the subway construction, and take the initiative to provide active service for the equipment at least three times a month, as long as the customer makes a phone call, they will rush to the construction site at the fastest speed to quickly troubleshoot and ensure that the Sany crane equipment can work efficiently at the construction site.

The Sany C9 excavator is entrusted with heavy responsibilities and runs an average of 16 hours a day

At the construction site of Changsha Metro Line 2, there is no Sany crane under construction, as well as the beautiful figure of Sany C9 excavator. Sany C9 series excavator is developed by thousands of Sany R&D engineers after two years of hard exploration, integrating the best technology at home and abroad, with the advantages of energy saving and environmental protection, high efficiency and durability, stability and reliability, etc., and has ranked 5656 in national sales for three consecutive years, becoming a well-deserved excavator in China.

At the construction site of Changsha Metro Line 1 and Line 2, 5 Sany excavators have been put into use. In order to ensure the normal operation of these five excavators, Hunan Zhongwang, the agent of Sany Heavy Machinery, organized a capable service team to participate in the escort, and paid a lot of hard work and sweat for the normal operation of the equipment. It is reported that since 2011, Sany excavator has been responsible for tunnel construction, with an average running time of 16 hours per day. The subway tunnel is located about 45 meters underground, and the underground construction air is thin, the oxygen content is low, and it has been in a high temperature state for a long time, and the construction environment is very harsh. In this environment, if the equipment cannot be repaired and maintained in time, the machinery may break down at any time, which will affect the progress of the project.

Sany excavator after-sales service personnel are like personal escort guards, they not only ensure the normal and safety of the equipment, but also the customer's confidence and responsibility for the Sany brand. (Zhao Hui, Wang Tengfei)
