Background technique

Crane refers to a multi-action hoisting machinery that lifts vertically and carries heavy objects horizontally within a certain range. It is also called a crane, an aerial crane, and a crane. The main features of a tire crane are: its driving cab and lifting control room are combined into one. 1. It evolved from the crawler crane (crawler crane). The crawler track and walking bracket part of the traveling mechanism are turned into a chassis with tires, which overcomes the shortcomings of the crawler crane (crawler crane) that the crawler shoes cause damage to the road surface. It belongs to material handling. Machinery; bridge crane is a lifting equipment that is placed horizontally over workshops, warehouses and stockyards for lifting materials. Because its two ends are located on tall cement columns or metal supports, it looks like a bridge. The bridge of the bridge crane runs longitudinally along the tracks laid on the elevated structures on both sides. It can make full use of the space under the bridge to lift materials without being hindered by ground equipment; it is the most widely used and largest lifting machinery. .

When the existing coiled material is transported, it needs to be lifted by a crane.
