塔式起重机因其结构、工作特点——塔身高、稳定性差,在设计、制造、使用和装拆等方面均需严格遵守有关标准、规范,否则极易发生事故。 据悉,塔机事故在我国还是屡见不鲜的。事故的原因有的是由于操作时违章,有的是由于塔机长期失修或管理不善,而绝大多数的塔机事故是在装、拆过程中发生的。 众所周知,塔机在装拆过程中始终处于不平衡状态,每一个工作步骤都应严格执行工艺规程和安全规 Because of its structure and working characteristics, tower cranes have high tower height and poor stability. They are required to strictly observe the relevant standards and norms in the design, manufacture, use, assembly and disassembly, etc. Otherwise, they are prone to accidents. It is reported that tower crane accidents are still uncommon in our country. Some reasons for the accident due to operational violations, some because of the tower crane disrepair or mismanagement, and the vast majority of tower crane accident occurred in the loading and unloading process. As we all know, tower crane in the process of assembly and disassembly has always been in an unbalanced state, every work step should be strictly enforced process rules and safety regulations
