What is the characteristic of tower crane
Tower crane, also known as tower crane, originated in Western Europe. According to the records, the first patent for the tower machine was awarded in 1900. In 1905, the tower was fixed with a crane, and in 1923 it was a prototype of a modern tower machine, and the first relatively complete modern tower was introduced in the same year. In 1930, Germany began mass production of tower machines and used them for construction. In 1941, the German industrial standard DIN8770 of the tower was announced. The standard stipulates that the lifting capacity of the tower machine is represented by the product (tm) of the hoisting (t) and amplitude (m). Then, let's take a look at the characteristics of it.
According to the structure and function characteristics of the towers are decomposed into several parts, and accordance with the requirements of seriation and generalizing, follow the principle of modular system and then each partition is divided into several modules. According to the requirement of the parameters, the appropriate module is chosen to make the tower machine with different technical performance characteristics to meet the specific requirements of the construction. The implementation of the integrated tower machine will help speed up the development of the tower product, save the cost of product development, and better serve the customer. The tower machine is divided into two types: rotary tower and bottom rotary tower. The former has a higher bearing capacity than the latter, and what we have seen in many construction sites is the tower machine which has the upper and higher lift of the roof. The ability to move is divided into: walking and fixing. The stationary tower is fixed in place, installed on the whole concrete foundation, or installed in a form of x-shaped concrete. In the construction of the house general use is fixed type.
From the perspective of the technology development of tower crane, while the new product emerge in endlessly, new products in the production efficiency, simple operation, easy maintenance and reliable operation were increased, but the tower crane technology, there is no fundamental change. The research of the tower machine is moving towards the combinatorial development. The so-called "combination" is centered on the structure of the tower.
