随着我国经济建设和改革开放进一步深入,建筑业的不断发展,各大中城市高层建筑建设不断增多,塔式起重机的应用越来越广泛,塔吊已成为高层建筑施工垂直运输的主动脉,但是重大塔吊事故频频发生,据统计全国每年发生的机毁人亡的重大事故不下百起。1.塔吊重大事故分析(1)塔吊本身质量在发生塔机事故和故障中,国产塔机占相当大的比重。尤其是一些小型塔机生产企业,塔吊安全运行电气控制存在较多问题。(2)塔吊运行时倾倒原因1)塔吊起吊超重。塔吊吊装违反操作规程,包括斜吊重物、重物与下面物
With the deepening of China’s economic construction and reform and opening up and the constant development of the construction industry, the construction of high-rise buildings in major cities has been on the rise.

According to statistics, there are not fewer than 100 major accidents that occur each year in the country. 1. Tower crane major accident analysis (1) tower crane itself In the event of tower crane accidents and failures, the proportion of domestic tower crane accounted for a large proportion. In particular, some small tower crane manufacturers, tower crane safe operation of electrical control there are more problems. (2) Dumping causes when tower crane is running 1) Tower crane is overweight. Tower crane lifting in violation of operating procedures, including hanging heavy objects, heavy objects and the following objects
