Recently, the online meeting of "Compilation Meeting of Group Standard "Construction Machinery and Equipment Crawler Clamshell Telescopic arm" edited by TYSIM came to a successful conclusion.The meeting was initiated by both the Foundation Construction Equipment Sub-Technical Committee of the National Construction Machinery and Equipment Standardization Technical Committee. Guo ChuanXin, Secretary General of the Piling Machinery Branch of the China Construction Machinery Society, attended the meeting and delivered a speech. Liu Shuang, Secretary-General of the National Construction Machinery and Equipment Standardization Technical Committee Participated in the meeting and gave a detailed introduction to the standard revision process. Xin Peng, Chairman of TYSIM, Executive Vice President Xiang ZhenSong, Professor and Doctoral Supervisor of the Institute of Mechatronics, School of Mechanical Engineering, TongJi University, YaoBao, Deputy Dean of the School of Mechanical and Energy Engineering, WenZhou RuiJi Technology, The general manager of the company, Hu ZhaoJu, and the former general manager of Shanghai ChengDi Geotechnical Design Co., Ltd., Zhou YuShi, participated in this compilation meeting.It is extremely urgent to formulate industry standards for crawler Clamshell telescopic armWith the rapid development of China economy, there are more and more deep foundation projects, and the problem of efficiently removing soil from deep foundation pits has been gradually solved by crawler-type Clamshell telescopic arm. Nowadays, crawler-type Clamshell telescopic arm have been localized, and there are many domestic enterprises that mass-produce such products. Tysim is one of them with rich experience.The "localization" process of crawler Clamshell telescopic arm has accelerated, but there is no corresponding national standard and industry standard for the production and use of crawler Clamshell telescopic arm in China, and there is no corresponding foreign standard for reference, so most construction machinery designers and construction units lack understanding of the use and maintenance of crawler-type Clamshell telescopic arm, resulting in some safety accidents.  In order to allow the manufacturing, production and use of crawler clamshell telescopic arm to have directive documents to follow, it is very necessary and urgent to formulate the industry standard of "ConstructionRecently, the project name of "Construction Machinery and Equipment Clamshell telescopic arm fight" as first mentioned in the plan of ZhongJi LianBiao [2022] No. 46 "Notice on Printing and Distributing the Second Batch of China Machinery Industry Federation Group Standards Revision Plan in 2022".  After the plan was issued, the drafting working group of "Construction Machinery and Equipment Clamshell telescopic arm " was quickly established. Tysim was tasked to be responsible for the main drafting work involving extensive collection of data, data analysis, and research and study.During the drafting process, Tysim aimed to set an advanced nature of the standard by combining the technical status of Clamshell telescopic arm in the industry based on the current technical status of products in the industry within China and absorbing the specific situation of Clamshell telescopic arm imported from abroad.  On this basis, the first draft of the standard draft of "Construction Machinery and Equipment Clamshell telescopic arm " was prepared. The draft stipulates the terms and definitions, models and parameters, technical requirements, test methods, inspection rules and marking, packaging, transportation and storage of  Clamshell telescopic arms.It is understood that the "Construction Machinery and Equipment  Clamshell telescopic arm " standard drafted by Tysim is the first in China. The final implementation of this standard will fill the gaps in the design and use of  Clamshell telescopic arm. It will accelerate the standardization and standardized construction of the Clamshell telescopic arm industry manufacturing, promoting the technological progress and construction specifications of the industry to have a profound impact on the entire industry.
