Description

Technical Field

[0002] When constructing high-rise buildings, due to the high construction height, tower crane jibs need to be installed at preset height positions.

[0003] At present, the installation of tower crane jibs mostly adopts the hanging basket method or the high-altitude platform method. The hanging basket method is to hang a hanging basket under high-altitude operation platforms such as climbing forms and climbing scaffolds. Construction workers enter the hanging basket through the high-altitude operation platform to install the tower crane jib. The high-altitude platform method is to first install the tower crane jib on high-altitude operation platforms such as climbing forms and climbing scaffolds.
