The steel reinforced concrete column has the advantages of high strength, small size of the section of a member, strong bond stress with concrete, concrete saving, increased use space, effectively improved bearing capacity of the member, reduced axial compression ratio of the member and the like, and is frequently used in large building structures.
At present, the hoisting of the steel skeleton column is mainly carried out by a tower crane.

The steel rib column is lifted from the ground by the lifting hook and then moved to a position to be installed.
The maximum weight that the tower crane can lift is related to the vertical distance of the lifting hook from the tower body, and the lifting hook is far away from the tower body, so that the maximum weight that the tower crane can lift is smaller. When the weight of the steel skeleton column is large (for example, more than 10 tons), the radius of the hoisting range of the tower crane can be far smaller than the length of the suspension arm, and at the moment, the tower crane needs to be arranged in an encrypted manner, so that the distance between two adjacent tower cranes is reduced.
