Description

Technical Field

[0001] This utility model relates to the field of tower crane attachment technology, specifically a tower crane attachment truss structure. Background Technology

[0002] In the construction of high-rise buildings and bridge piers, tower cranes are usually required to have a high working height. When the working height exceeds the independent height of the tower crane, it is necessary to add an attachment device to the tower crane to ensure the stability of the tower crane structure.

[0003] Tower crane attachment points are generally set on shear walls, main beams, columns, and piers. However, due to the constraints of on-site construction conditions, sometimes it is impossible to attach them to the above-mentioned positions, or the attachment angle does not meet the requirements. Based on this situation, it is urgent to design a truss structure that can effectively meet the attachment requirements of tower cranes. Utility Model Content
