What requirements shall be met for the installation method of tower crane attachment device

The length of each strut of the structural member of the tower crane attachment device can be adjusted. Each strut should be kept in the same plane. The length of the top block and strut should be adjusted to make the axis of the tower body vertical. Generally, after the attachment, the theodolite shall be used to check and adjust the perpendicularity of the tower crane shaft line.

The perpendicularity of the tower body below the attachment point shall not be greater than 2/1,000, and the perpendicularity of the tower body above the attachment point shall not be greater than 3/10,000. The adjustment of the verticality can be realized by adjusting the advance and retreat of the bolt on the strut.

The installation of the attachment device of the tower crane shall comply with the requirements of the instruction of the tower crane. The erection distance of the attachment device and the free height above the attached wall point shall not be arbitrarily excessively long (the specific attached wall point is allowed to be appropriately adjusted in the range of 1m according to the actual situation of the building). The extra long attachment brace should be designed separately and checked for strength and stability.

The first attachment distance of the tower crane is 24 m from the foundation surface. As the adding node of the tower crane increases, the corresponding number of attachment is increased. The maximum height of the tower crane cantilever shall not exceed 27 m.

The frame sleeve (also known as ring beam sleeve) is welded by Angle steel and steel plate. When in use, the frame sleeve is on the standard section. The standard section is secured by the top block with 8 adjusting bolts at the four corners. The frame is connected with the building by 3 or 4 struts.

The connection point between the struts and the building should be selected on the concrete column or concrete ring beam. The embedded part is combined with concrete, and the embedded part or the wall bolt is connected with the building structure.

It is very dangerous to use expansion bolts instead of embedded parts, or use cable and wind rope instead of attachment support, because the attachment device and its accessories are the same products produced by the manufacturer as the standard section. The use of substitutes reduces the strength and stability of the attachment device
