FIELD: construction industry.
SUBSTANCE: lifting system used for performing maintenance of multistory structures consists of vertical H-rails mounted on the structure surface and at least one lifting block for each H-rail, which is equipped with the means of its being attached to H-rail and means of movement relative to H-rail. H-rails are located at some distance relative to each other along external surface of structure. Individual lifting blocks are installed on each H-rail, interconnected at least with one girder section, and comprise a uniform lifting system. Girder section consists of at least one load platform which is divided with guiding rollers into orthogonal cells wherein there shall be placed individual trays installed on drive wheels that are provided in load platform of girder section. Guiding rollers of each cell are located along its perimeter, besides some of guiding rollers are made retractable.
EFFECT: invention allows improving ease of use of system when transferring loads using trays.
