Crane trucks are mostly composed of hanging systems and winches, and some lift heavy objects through hydraulic systems. Crane truck mainly includes lifting mechanism, luffing mechanism, slewing mechanism, hoisting mechanism, metal structure and automobile chassis. Lifting mechanism is the basic working mechanism of Crane truck, mostly composed of hanging system and winch, and some lifting heavy objects through hydraulic system. The luffing mechanism is only equipped on jib cranes. The amplitude decreases when the boom is raised, and increases when the boom is lowered. There are two types: balanced luffing and unbalanced luffing. The slewing mechanism is used to rotate the boom, and is composed of a driving device and a slewing support structure. The metal structure is the frame of the crane. The main load-bearing components such as bridge, boom and gantry can be box structure or truss structure, or web structure, and some steel can be used as supporting beam.

To survive and develop in this field, China��s Crane truck manufacturers need to do a lot of things. Due to the increase in market demand, manufacturers are also required to innovate continuously, and continue to develop products on the basis of ensuring the performance of Crane trucks. New products with larger tonnage meet the needs of the market. Only in this way can we obtain nutrients and vitality from the market so that we can survive, develop in survival, and grow stronger in development.
