Crane refers to a multi-action lifting machine that lifts and moves heavy objects vertically and horizontally within a certain range. Also known as overhead crane, aerial crane, crane.

The main characteristics of the tire crane are: its driving cab and lifting control room are combined into one, which is evolved by a crawler crane (crawler crane), which turns the crawler and the walking bracket part of the walking mechanism into a chassis with tires, overcoming the shortcomings of the crawler crane (crawler crane) crawler shoe to the road surface, which belongs to material handling machinery.

Overhead crane is a lifting equipment for material lifting over workshops, warehouses and material yards. Because its ends sit on tall cement columns or metal supports, it is shaped like a bridge. The bridge frame of the overhead crane runs longitudinally along the track laid on the elevated frame on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is the most widely used and the most numerous lifting machinery.

Some of the working characteristics of lifting equipment are intermittent movement, that is, the corresponding mechanism of taking materials, moving, unloading and other actions in a working cycle is alternately working, and cranes are more and more widely developed and used in the market. Due to the frequent occurrence of some accidents without outrigger lifting and lifting loading, the driving speed is also faster than that of crawler cranes (crawler cranes); The operation is stable, the lifting capacity is large, and it can be lifted and walked within a specific range, but it must be ensured that the road is smooth and solid, the tire pressure meets the requirements, and the lifting distance from the ground shall not exceed 50CM; It is forbidden to walk long distances with load. In order to ensure the safety of the operation, it is basically prohibited to carry out lifting operations without outriggers in China. The crane uses steel wire rope varieties including phosphating coated wire rope, galvanized steel wire rope and smooth steel wire rope.
