HOISTING SYSTEM FOR TOWER-TYPE TALL STRUCTURES Russian patent published in 2009 - IPC B66B9/00 

FIELD: machine building.

SUBSTANCE: present invention pertains to lifting machine building. The hoisting system for servicing tower-type tall structures has vertical rails with an H-shaped section, mounted on the outer surface of the structure, a self-moving hoisting block for each rail with H-shaped section, made with means for fastening it to that rail and with means of moving it relative that rail. According to the invention, on each section along the height of the structure, the self-moving blocks along the circumference are joined to each other by truss sections with platforms for persons and equipment, forming a circular lifting unit, moved along the H-shaped rails on that section. The said truss sections of each circular lifting unit are provided with folding doors and manholes for communicating with entrances of the tower type structure and/or circular lifting units with each other. In the profile planes of the inner cells of the self-moving hoisting blocks, there are folding doors enabling movement of persons and equipment along the whole length inside the circular lifting unit.

EFFECT: invention increases operational capabilities of servicing tall structures.
