Description

[0002] In the installation of building steel structures, the lifting, positioning, and installation of steel components are core links. Traditional construction methods mostly rely on manual labor in conjunction with simple lifting equipment (such as winches, cranes, etc.). However, this method has significant shortcomings: First, manual operation is inefficient and limited by workers' experience and physical strength, making it difficult to accurately lift large-span, heavy steel components; second, conventional equipment lacks height and horizontal adjustment functions, requiring repeated adjustments to the position of steel components, which prolongs the installation period; in addition, existing devices often use temporary bolt fixation or manual calibration in the positioning and fixing links, which has poor stability and is prone to offset or safety hazards.
