How to reinforce the lower part of the steel structure of the construction elevator on the roof of the non - air defense garage
In this way, the free height is the base plane of the tower foundation per square load, there is no calculation of partial coefficients, close to 5 tons, 50KN. Lifting, consider the torque, the edge of the pressure is even greater. Such a large load, placed in the plate can not be placed on the beam is not. Can only be arranged in the stigma. However, even if the column doubled fortunately. How to solve the foundation?
On the basis of the natural foundation of the tower crane, you can balance the freedom of the height of the crane hoisting moment, a considerable weight. To 5 m X5 m X1.4 m tower base to calculate the weight of 84 tons.
Tower crane can not be placed on the basement roof. The height of the tower crane is about 40 tons, and the weight of the standard section after the wall is not counted. More important is the tower crane foundation
