一、机械设备一、为什么要强调桥式起重机的安全技术问题?这是由于桥式起重机是高空运行的起重运输机械,专业性强,技术复杂程度较高,不安全的因素多,容易发生故障。据某城市统计,起重事故在重大伤亡事故中占22.5%,其中在冶金、机电等部门高达30～50%。所 First, the mechanical equipment First, why should emphasize the safety and technical problems of overhead traveling cranes? This is because the overhead traveling crane crane is a high-altitude operation of transport machinery, highly specialized, high technical complexity, unsafe factors, prone to malfunction. According to statistics of a city, lifting accidents account for 22.5% of the major casualties, of which 30-50% are in metallurgy, electromechanical and other departments. The
