During group discussions. Chief Engineer of PERI LLC Anatoly Malyutin
Nadezhda Rozantseva, Associate Professor of the Department of Construction Organization at SPbGASU and Candidate of Engineering Sciences, conducted the research project "Development of a Technology for Crane-Free Assembly of Large-Span Structures" as part of the 2025 grant competition for research projects by SPbGASU academic staff.
The relevance of developing a technology for the rapid installation of large-span temporary structures using rail lifts is determined by several factors:
High costs: traditional methods require significant amounts of materials and labor; long construction and installation times: complex structures take a long time to construct and transport; environmental concerns: large amounts of waste are generated after dismantling.
The proposed technology is aimed at minimizing the impact of these factors:
Resource savings: quick installation reduces the need for resources and equipment, and the repeated use reduces the amount of required materials; increased productivity and process automation: the ability to quickly assemble reduces project implementation time, and the system ensures increased efficiency of the installation process; design flexibility: the lift design can be adapted to various environmental conditions and can be used in the construction of bridges, overpasses, hangar ceilings, and other large structures; optimal use of space: the superstructure is lifted directly from ground or water level, requiring no additional space for equipment, which helps save space; multiple use: after completion of its operation, the system, including the superstructure, can be dismantled and reinstalled in another location; improved environmental sustainability: repeated use reduces the amount of waste after dismantling, which reduces the impact on the environment.
During the research and development process, consultations were held with specialists from PERI LLC and Stroykomplekt Institute JSC, and a visit was made to a technology park in Noginsk, Moscow Region. PERI provided its facilities for modeling the lifting system, and group discussions of the idea were held with the specialists. The partners proposed using self-climbing system components developed by PERI LLC as a reference for the lifting system, which enabled the selection of two optimal design solutions.
Development of the crane-free installation technology continues. Calculations must now be conducted to determine not only the unit's ability to lift the stated loads but also the strength of its lifting frame and lifting platform. A patent application for the lifting technology and the folding outer casing is pending.
Once developed, the technology will be widely used in construction projects, reducing their negative impact on the environment and contributing to resource conservation.
