How to choose a tower crane suitable for your own construction?

Recently, the demand for construction has continued to increase. 

Are you troubled how to choose a tower crane suitable for your own construction? Come explore with me today!

The selection of tower cranes should comprehensively consider the height of the building; the structure type of the building; the size and weight of the components; the construction progress, the division of the construction flow section and the quantity of work; the layout of the site and the surrounding environmental conditions. At the same time, the site and building structure for installing and dismantling the tower crane must meet the requirements for tower anchorage and climbing.

1. First, determine the required parameters according to the construction object, including the amplitude (also known as the radius of gyration), lifting capacity, lifting moment and hook height, etc.; however, according to the technical performance of the tower crane, select the model of the tower crane .

2. Secondly, according to the construction progress, the division of the construction flow section, the engineering quantity and the required lifting times, and the layout of the site, determine the number of tower cranes, the installation location, and the direction of the track foundation.

3. According to construction experience, it is most economical to use rail-mounted tower cranes for high-rise buildings with 16 floors and below; for high-rise buildings with more than 25 floors, it is advisable to use attached tower cranes or internal climbing tower cranes.

4. When choosing a tower crane, you should pay attention to the following items:

1) When determining the form and height of the tower crane, issues such as the position of the anchor point of the tower body corresponding to the building and whether the balance arm of the tower crane affects the normal rotation of the jib should be considered.

2) Under the operating conditions of multiple tower cranes, the height difference of adjacent tower cranes should be properly handled to prevent the two towers from colliding and to ensure that they do not interfere with each other.

3) While considering the tower crane installation, consideration should be given to the tower crane's jacking, height connection, anchoring, tower dropping, dismantling and other matters after completion. For example, whether the lifting arm and balance arm are on the building, the parking position and operating conditions of auxiliary equipment, and whether there are obstacles in the transportation road in the site, etc.

4) When considering the installation of the tower crane, the installation position of the jacking sleeve (that is, the introduction platform or the introduction track of the tower should be in the same direction as the jib) and the installation position of the anchor ring should be correct.

Attention should be paid to the support form of the external scaffolding and the distance from the building to avoid conflicts with the tail rotation of the turntable of the lower slewing tower crane.

5) At the same time, it should be noted that due to the tower crane's tall and upright structure, complex structure, frequent assembly and disassembly, and high technical requirements, it also brings certain difficulties to safe construction and production, and accidents of tipping and collapse are prone to occur. The safe installation, disassembly, and operation of tower cranes are particularly important. important.
