What are the characteristics of tower crane?

Tower crane, also known as tower crane, originated in western Europe. According to records, the first patent for tower crane for construction was issued in 1900. 1905 saw the crane with fixed tower and boom, 1923 made the prototype of modern tower crane, and the first relatively complete modern tower crane appeared in the same year. 1930, Germany has started mass production of tower cranes and used them in buildings. 194 1 year, the German industrial standard DIN8770 on tower cranes was published. According to the standard, the product (tm) of lifting weight (T) and amplitude (M) is used to express the lifting capacity of high-torque tower crane. Then, here is a brief introduction to the characteristics of forklift rental in Guangzhou. 1. From the technical development of tower crane, although new products emerge one after another, and new products have improved in production efficiency, simple operation, convenient maintenance and reliable operation, the technology of tower crane has not changed fundamentally. The research of tower crane is developing in the direction of combination. The so-called combined type takes the tower structure as the core. Secondly, according to the structural and functional characteristics, the tower is divided into several parts, and each part is divided into several modules according to the requirements of serialization and generalization and the principle of modular system. According to the parameter requirements, select appropriate modules to form tower cranes with different technical performance characteristics to meet the specific needs of construction. The implementation of combined tower crane is helpful to speed up the development progress of tower crane products, save product development costs and better serve customers. 3. Tower cranes are divided into two categories: upper rotary tower cranes and lower rotary tower cranes. Among them, the former has higher bearing capacity than the latter. In many construction sites, what we see are tower cranes with top-to-top lifting and joint connection. According to whether it can move, it can be divided into walking type and fixed type. The tower body of the fixed tower crane cannot rotate, and it is installed on the whole concrete foundation or X-shaped concrete foundation in a strip shape. In housing construction, it is generally fixed.
