大起重量电动桥式起重机工作时,起重机停止运转须要修理的最大多数情况,是由于这些机构传动装置的行走輪及轨道头部很快磨损的毛病引起的;这些零件的磨损都是由于很大的超载所致。当起重机的正常工作条件遭到破坏时,在一定的时间间隔内,这些超载荷就会出现并起作用。众所周知,起重机传动装置零件上的附加 Lifting heavy duty electric bridge crane work, the crane stopped working in the most need to repair the majority of the situation is due to the transmission mechanism of these institutions and the head of the track faster wear and tear caused by the wear of these parts are due to large Due to overload. When the normal working conditions of the crane are destroyed, these overloads will appear and work for a certain time interval. It is well known that crane gear components are attached
