L68A1 Mast Sectionn this paper, the selection of tower crane is discussed to properly solve the type of selection
Tower crane is the first choice of hoisting and transportation equipment in the construction of high-rise and super high-rise buildings.

When choosing the tower crane, the first thing is to choose the jack up crane with proper parameters. 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.
