L68A1 Mast Section Precautions, parameters and type selection of tower crane

12-12-2019

When choosing tower crane, it generally depends on your building plan and the size of single floor plan area. In this paper, the tower crane construction machinery factory (http://www.fx68.net) briefly describes the precautions for the selection of tower crane, including the selection of parameters and types of tower crane.

1. It is generally recommended to arrange a tower crane about 1000m2. If the area of a tower crane is too large, it will be too busy.


2. Look at the length and width of your building. Generally, the arm length of the tower crane is about 50m, and its effective range is a circle with a radius of 50m. When arranging the tower crane, the most buildings should be covered as much as possible, and the reinforcement yard and formwork yard should also be covered to avoid secondary handling.


3. Model of tower crane: in general building construction site, the lifting weight of arm end is about 1t ~ 1.5T.

The first thing is to choose the suitable parameters of the jack up tower crane. Among the parameters, the most important are the main parameters: amplitude, maximum amplitude lifting capacity and lifting height. However, when determining the main parameters, it is also necessary to determine which type of tower crane to choose: internal climbing tower crane or attached tower crane; luffing boom tower crane or trolley luffing horizontal boom tower crane. Experience shows that the function of a 40 t · m internal climbing tower crane is equal to that of an 80 t · m attached tower crane. The attached tower crane needs to be equipped with more standard sections of the tower body, and a necessary number of attached rods and corresponding anchors. Therefore, it is economical and reasonable to choose the internal climbing tower crane in order to save one-time investment. However, in order to ensure the safety of production and obtain the best benefit, the construction organization design of hoisting construction with internal climbing tower crane and the dismantling scheme of tower crane after the completion of the structure should be done well.




At present, most of the domestic self elevating tower cranes are trolley luffing horizontal boom self elevating tower cranes, only a few factories produce a small number of luffing luffing boom type tower cranes. Therefore, from the perspective of supply, it is more convenient to select horizontal boom tower crane. However, when it is necessary to build a tower like high-rise building in a forest like environment, the luffing boom tower crane is a reasonable choice. Because the boom can pitch freely, the boom will not swing over the adjacent high-rise buildings, nor collide with the surrounding high-rise buildings. It is because of the above characteristics that the boom type self lifting tower crane is used in the construction of HSBC building in Hong Kong. For the same reason, some Southeast Asian countries have introduced some boom type self elevating tower cranes from China in recent years for the construction of high-rise buildings.
