A tens of meters of aerial work platform has caused sling breakage and caused casualties. Is the quality of the equipment manufacturer not enough, or the maintenance of the equipment leasing party is not in place, or is the construction worker's illegal operation? Recently, Haiyan National Inspection and Testing Technology Co., Ltd. (hereinafter referred to as “National Inspection Companyâ€) undertook an analysis case involving a safety accident involving tower cranes. Through the investigation, inquiry and technical analysis means, the inspection company's failure analysis technical service team found out the cause of the failure and breakage of the screw-on joints of the aerial work platform, and provided objective and unbiased data support for the accident liability judgment.
In recent years, safety accidents related to tower cranes are not uncommon. There are many cases in which the national inspection company accepts such accident analysis cases. It is found through failure analysis that some of the accidents are caused by product quality problems, but more because the disassembly personnel are not After formal training, the tower crane user does not pay attention to the daily inspection and maintenance of the equipment. In the process of investigation and analysis of various types of safety accidents, failure analysis is an indispensable technical means, which is a comprehensive reflection of the level of inspection and testing capabilities. In recent years, the national inspection company has invested a large amount of equipment and technology in the construction of failure analysis capabilities. In 2014, only 86 cases of failure analysis were carried out, providing technical support for quality safety accident analysis in passenger trains, automobiles, wind power generation equipment, chemical equipment, etc., and solving trade disputes for enterprises through failure analysis services. It has improved 26 processes and avoided nearly 10 million yuan in trade claims, which has established a good reputation and influence in the industry.

Accidents occurred in 28 provinces across the country. According to incomplete statistics, 93 people were killed and 136 injured in these accidents. Most of the dead and wounded are tower crane drivers. It is worth mentioning that there are about 26 major serious accidents involving three or more deaths, accounting for 20.3% of accidents and security risks exposed by the news media. Analysis of the cause of the tower crane accident occurred in 2013, nothing more than two reasons: tower crane quality problems and illegal operation. Therefore, in order to avoid the frequent occurrence of tower crane accidents, in addition to the tower crane manufacturers continue to improve product quality, standard operations, strengthen third-party supervision and testing, in order to achieve long-term security.
