Cranes are playing an increasingly important role in human life. There are many kinds of cranes, which can realize lifting, loading and unloading, hoisting and other functions. There are small cranes, large-tonnage cranes and intelligent cranes. The appearance of these equipments effectively solved the problems of engineering hoisting and transportation.

structure

Crane mainly includes hoisting mechanism, running mechanism, luffing mechanism, slewing mechanism and metal structure. Lifting mechanism is the basic working mechanism of crane, which is mostly composed of suspension system and winch, and some lift heavy objects through hydraulic system. Running mechanism is used to move heavy objects vertically and horizontally or adjust the working position of crane, and generally consists of motor, reducer, brake and wheel.

The luffing mechanism is only equipped on the jib crane, and the amplitude decreases when the jib rises and increases when it falls, which can be divided into two types: balanced luffing and unbalanced luffing. The slewing mechanism is used for slewing the boom and consists of a driving device and a slewing support device.

Metal structure is the skeleton of crane, and the main load-bearing components such as bridge, boom and gantry can be box structure or truss structure, or web structure, and some can use section steel as supporting beam.
