Today, due to increasing technology and population density, the number of skyscraper constructions and residences is increasing rapidly. Tower cranes help in the rapid construction of constructions in terms of the ease of service of the machinery and equipment they provide during the construction. Accidents occurring in the construction sector in Turkey and around the world show that 30% of them take place in this type of construction. For this reason, analyzing the risky situations created by tower cranes regarding their positive aspects is very important in preventing and controlling serious and catastrophic accidents. In the study, the risks that may occur in tower crane environments were determined from accident records, obtained accident analyses, risk analysis reports, and literature studies. The motivation of the study is to analyze and manage the risks associated with tower cranes to prevent serious accidents in rapidly growing high-rise construction. The identified risk sources were evaluated with event tree analysis and scenarios. Lack of maintenance and checks, incorrect installation and assembly, and electric initiating events are analyzed in detail. As a result of the analysis, the probability of a catastrophic event was found to be 2.1% for the Lack of maintenance and checks starting event, 0.8% for the incorrect installation and assembly starting event, and 0.4% for the electric starting event. If serious events are taken into account, the probability increases to %33.04. Therefore, after risk analysis is done, it should be managed well and significant risks should be prevented from increasing by using the Plan-Do-Control-Act (PDCA) standard.
