摘　　要：针对同时装设工作制动器和安全制动器的铸造起重机起升机构,分析在传动链发生故障的情况下高温钢水包的下滑量和倾斜量,对安全制动器与工作制动器同时上闸和安全制动器滞后于工作制动器上闸的2种工况产生的制动距离和钢水包的可能倾斜程度进行了比较,从而为制动系统制动时间的控制提供依据,保证所吊物品和起重机自身的安全。For the ladle crane with the lifting brake and safety brake, the paper analyzes the falling distance and the tilting angle of high temperature steel ladle if the hoisting mechanism failure. It compares the brake distance and possible tilting angle under the two conditions of the safety brake and lifting brake simuhaneously applied and lifting brake applied earlier than safety brake. It provides a basis for control to brake time of the brake system and the guarantee of the safety of the hoisted load and the crane itself.
