TAKING ADVANTAGE OF THE PULL-UP METHOD FOR ERECTION OF LARGE-SPAN COATINGS WITH LIFTING MODULES

The article presents an analysis of the method of lifting large-span coatings using the pull-up method and introduces a new structural-technological solution for erecting coatings using mechanized technological equipment in the form of a lifting module. According to the solution, the load-bearing beams of the coating are moved in the space between paired columns of the frame, resting on the lifting modules. Guide profiles fixed to the inner surfaces of the columns serve as supports for the alternating support of the platforms of the lifting module, which pushes the coating beams in the inter-column space. The developed solution optimizes the lifting processes and reduces the duration of lifting works by minimizing the number of installations works to operations for fixing the beams of the coating at the design height and automating the processes of pushing the coating with lifting modules.
