[0002] A crane refers to a multi-action lifting machine that can lift heavy objects vertically and carry them horizontally within a certain range. The working characteristic is intermittent movement, that is, the corresponding mechanisms of material collection, transportation, unloading and other actions work alternately in a working cycle. Cranes are developing and being used more and more widely in the market.
