154HC Mast Section Reasonable arrangement and height balance coordination of tower crane position
1. The plane layout of the tower crane shall be based on the actual situation of the site, so that the whole construction surface can be covered by the scope of the tower crane as much as possible, without or without blind area, and there shall be enough safety distance between adjacent tower cranes.
2. Avoid nearby buildings and structures (such as high-voltage wires, etc.) within the slewing range of tower crane
3. It is necessary to ensure that the buildings within the scope specified in the tower crane instructions have reliable anchoring positions (balcony, middle structure changes and positions should be avoided).
4. When several tower cranes are working at the same time, they may cross each other on the horizontal plane. In order to prevent the collision accident of the tower crane boom, the installation height of the tower crane shall be staggered in strict accordance with the provisions of the construction scheme. According to the construction safety standards, the fixed tower crane in the operation of multiple tower cranes: the distance between the end of the low tower arm and the high tower body shall not be less than 2m, and the vertical distance between the high tower hook and the low tower shall not be less than 2m.
5. When several tower cranes are working at the same time, the height difference between the tower cranes before and after anchoring and the time difference between anchoring shall be considered carefully to ensure that the height difference between the tower cranes is maintained during the whole construction process of the main structure. In case of special circumstances or conflicts with the plan, it shall be adjusted in time.
6. Ensure that after the completion of the project, there is still sufficient space for disassembly and removal of components from the construction site.
