起重机电气应急运行技术开发与应用

Development and application of electrical emergency operating technology for crane

通过开发起重机电气应急运行技术,有效解决了桥式起重机因发生电气故障而无法继续正常运行的问题,从而提高了起重机的可开动率。介绍了大小车应急系统及起升机构单动控制技术的设计原理和方案。

By developing the crane electrical emergency operating technology, the paper solves the problem that the bridge crane is cannot be operated normally due to electrical fault, and improves the crane functional rate. The paper introduces the design mechanism and scheme for the single-action control technology of trolley and crane emergency system and lifting mechanism.
