Variable frequency speed control bridge crane is a widely used crane because its use is not affected by ground objects, and it can effectively save space during use. It is usually used indoors, and can be laid with the help of indoor metal frames or cement columns. The variable frequency speed regulating bridge crane can move longitudinally with the help of the laid track, and the hook can move laterally with its own advantages, so its working area is fixed, which can maximize the use of ground space for work. The variable frequency speed regulating bridge crane needs to be regularly inspected and maintained during use in order to improve its service life. Generally, when we are inspecting, we are particularly likely to notice whether the appearance of the crane is cracked, whether there are cracks, and whether there is dust accumulation. However, these are not particularly important. We must regularly check whether the screws of the crane are tightened, whether the lubrication is in place, and whether the steel wire rope is worn or broken.
