A crane refers to a multi action lifting machinery that vertically lifts and horizontally transports heavy objects within a certain range. Also known as overhead crane, aerial crane, or crane. The main feature of a tire mounted crane is that its driving cab and lifting control cabin are integrated, evolved from a crawler crane (crawler crane), which transforms the tracks and walking brackets of the walking mechanism into a chassis with tires, overcoming the disadvantage of damage caused by the crawler shoes of the crawler crane (crawler crane) to the road surface. It belongs to material handling machinery. Bridge crane is a lifting equipment that is horizontally mounted over workshops, warehouses, and material yards for material lifting. Due to its two ends located on tall cement columns or metal supports, the shape resembles a bridge. The bridge of an overhead crane runs longitudinally along the tracks laid on both sides of the elevated structure, allowing for full utilization of the space below the bridge to lift materials without being hindered by ground equipment. It is the most widely used and numerous type of lifting machinery. Some working characteristics of lifting equipment are intermittent movements, that is, the corresponding mechanisms for picking up, transporting, unloading, and other actions in a working cycle work alternately. The development and use of cranes in the market are becoming increasingly widespread. Due to the lack of support legs for lifting and frequent accidents during lifting, the traveling speed is also faster than that of crawler cranes (crawler cranes); Stable operation, large lifting capacity, capable of lifting and walking within a specific range, but must ensure that the road is flat and solid, the tire pressure meets the requirements, and the lifting distance from the ground must not exceed 50CM; Long distance walking with load is prohibited. To ensure work safety, lifting operations without using legs are generally prohibited in China. The types of steel wire ropes used for cranes include phosphating coated steel wire ropes, galvanized steel wire ropes, and smooth steel wire ropes
