整备150t吊车起升机构改进

Improvement of Lifting Mechanism of Stood-by 150t Crane

针对整备150t吊车摘、挂钢水罐不稳严重影响吊车安全运行的问题,分析了该吊车起升机构的卷筒、滑轮组及吊钩结构形式存在的问题,采取相应的改进措施后,提高了吊车操作时的稳定性,节省设备事故处理时间约20h,保证了生产的稳定顺行。

In view of the problem that the safe operation for the stood-by 150t crane was seriously influenced due to unstable taking off or hanging on the molten steel tank,the problems existing in the reel,pulley block and structural style of the hanging hook in terms of the crane lifting mechanism were analyzed.After taking the corresponding improvement measures,the stability of the crane in operation was improved,and thus the time for dealing with the equipment accident was saved about 20 h,which guaranteed the stable and smooth production.
