Determination of the basic parameters of the tower crane The basic parameters of the tower crane refer to the height, arm length and hoisting weight of the tower crane. Except for very special circumstances, the lifting weight of the tower crane generally does not need to be considered. The length of the tower boom can be preliminarily determined according to the length, width and height of the building. The length of the arm is suitable to ensure that it can cover all the projects and have a little margin. The tower cranes that are often seen at present generally have arm lengths of 30m, 40m, 50m, 55m, 60m, 70m, and several types. Tower cranes with larger arm lengths are rarely used due to other conditions on the site, so be careful when selecting them. The height of the tower crane only needs to be 10-15m higher than the height of the building. The lifting weight of the arm end is determined by the weight of the object to be lifted given by the civil construction personnel. In general frame-structured buildings, the tower crane needs to lift concrete buckets, and the hoisting weight at the arm end is relatively large; while for high-rise buildings with concrete structures, the requirements for this are lower. After the above three parameters are determined, the type of tower crane can be preliminarily determined. Guilin Tower Crane
