tower crane is the first choice of lifting transport equipment in the construction of high-rise and super-high-rise buildings This paper discusses the selection of Tower Crane and properly solves the problem of which tower crane to choose. When choosing tower crane, the first thing is to select the proper parameters of jack-up tower crane. Among the parameters, the most important are the main parameters: amplitude, maximum lifting weight and lifting height. However, when determining the main parameters, it is necessary to determine which type of tower crane to choose: Internal Climbing Tower Crane or attached tower crane, pitching jib crane or trolley jib horizontal jib crane. The experience shows that the function of one 40t / m internal climbing tower crane is equal to that of one 80t / m attached tower crane. The attached tower crane should be equipped with more standard sections of the tower body, and have the necessary number of attached rods and corresponding anchorage pieces. Therefore, from the point of view of saving one-time investment, it is economical and reasonable to choose the internal climbing tower crane. However, in order to ensure the safety of production and obtain the best benefits, the construction organization design and the dismantling scheme of the tower crane should be done well. At present, the homemade self-lifting tower crane is mainly a trolley-type horizontal boom self-lifting tower crane, only a few factories produce a small amount of pitch-type boom-lifting tower crane.

Therefore, from the point of view of supply, the selection of horizontal boom tower crane is more convenient. However, in the environment of high-rise buildings such as forest, pitching jib crane is a reasonable choice when building a tower-like high-rise building. Because the STRUT JIB can be pitched freely, the boom will neither swing over the adjacent high-rise buildings nor collide with the surrounding high-rise buildings. It is precisely because of the above-mentioned characteristics of boom-type self-lifting tower cranes, so the HSBC tower in the construction of the use of six boom-type self-lifting tower cranes. For the same reason, some Southeast Asian countries have introduced some boom-type self-elevating tower cranes from our country in recent years for the construction of high-rise buildings.
