L68B2 Mast Section Rational arrangement of tower crane machinery and equipment
When using tower lifting equipment, due to the fact that many equipment may be used according to different environments, reasonable layout requires attention. The following describes the reasonable layout and high balance of the tower crane position:
1, the layout of the tower crane should be based on the actual situation on the ground, so that the scope of the tower crane lifting covers the entire construction surface as far as possible, and no or less blind areas are generated. The adjacent tower crane is guaranteed to have sufficient safe distance.
2, to avoid the tower swing range within the vicinity of buildings and structures(such as high voltage wires, etc..)
3, to ensure that the tower hanging instructions within the scope of the building has a reliable Anchorage position(balcony, central structure and location should be avoided).
After the completion of the project, there is still enough space to facilitate the dismantling and removal of parts from the construction site.
5, multiple tower cranes operate at the same time, may cross each other on the horizontal plane, in order to prevent the tower crane arm collision accident, the height of the tower crane should be strictly staggered with each other in accordance with the construction plan. According to the construction safety standards, fixed tower cranes in multiple tower lifting operations: the distance between the end of the low tower arm and the high tower body must not be less than 2M, and the vertical distance between the high tower hook and the low tower must not be less than 2M.
6, multiple tower crane at the same time, should carefully consider the Anchorage before and after the tower crane height difference and Anchorage time difference, to ensure that the entire construction of the main structure maintains the height difference between the towers. In case of special circumstances or conflicts with the programme, adjustments should be made in due course.
