FIELD: engineering industry. ^ SUBSTANCE: lifting system consists of vertical H-rails, self-powered lifting block for each H-rail, which is provided with attachment device thereto and with device of movement relative to that rail. The above parts are mounted on external surface of structure. Self-powered lifting blocks and girder section of this system are equipped with doors and access doors meant for interacting with doors, access doors or windows of structure and/or these systems between each other. System is equipped with common risers each of which is provided with a number of horizontal beams whereto there attached is H-rail. Each individual horizontal beam is located at the corresponding level of the structure, and distance change between front plane of the riser and the above rail is compensated for owing to the appropriate change of width or location of that beam. Common riser is connected through erection clips to metal flanges of load-carrying members of the structure's design. As per the second version of invention H-rails are mounted on external surfaces of at least two structures. ^ EFFECT: inventions allow providing ease of system installation for example on cone-shaped structures. ^ 68 cl, 12 dwg |
