摘要
主要论述了对吊运熔融金属的通用桥式起重机进行改造时,在电路控制系统方面容易出错的几种情况,具体为:独立作用的两套制动器、接触器正反向故障保护功能、两套控制不同回路的限位装置。
This paper mainly discusses several error conditions in controlled circuit which are happened when reforming general over head traveling cranes of hoisting molten metal.Include two sets of independent brakes,forward and reverse error protection of the contactor,stop means which control different circuit.
