Preparation for tower crane installation

Before the tower crane is installed, the construction site should be inspected and calculated. So let's talk about it briefly.

First of all to determine the tower crane device method.

There are three common device methods for jack-up tower cranes, namely, fixed feet installed in large concrete blocks, large chassis pressure and walking device methods. Different device methods have different requirements on the ground pressure of the root soil, and different types of tower cranes have different pressure on the ground. In addition, the depth of the foundation and slope type of the project also affect the device method of the foundation of the tower crane, and then affect the selection of the tower crane, so the selection needs to have certain practical experience, and carefully read the selection of tower crane commodity manual about some chapters of the foundation.

On the other hand, determine the starting height.

In common use self-lifting tower crane can be as building rises, when the height of tower crane beyond "comfort height", if the rise again, need to choose "attached to the wall" method, which is the tower crane and the "anchor" together in construction engineering, the height of the different types of tower crane attached to the wall for the first time, the distance between each two "attached to the wall" force is different also. Tower crane attached to in engineering have rated the lateral to pull, it needs some engineering can reach will be completed intensity, and if the construction speed is quick, attached some did not reach the strength of the booking, this will affect the construction progress, this kind of situation should think choose comfortable height larger type of tower crane, and is particularly important in winter construction.

Be aware of your surroundings.

The surrounding environment restricts the selection of tower crane leasing. Attention should be paid to the height of surrounding buildings and whether there are high-voltage lines. To avoid accidents and delay the project.

For tower crane equipment, the impact of the environment is relatively large. Therefore, before installation, we must first understand whether the use of tower crane site to meet the needs of tower crane equipment.
