INSTALLATION METHOD OF LONG STRUCTURES Russian patent published in 2009 - IPC B66F19/00 

FIELD: construction industry.

SUBSTANCE: installation method of long structures with the aid of airborne vehicle includes step-by-step connection of mounted long structure sections to the external load system of the airborne vehicle, their transportation to the installation site and long structure mounting via sections installation on each other. The section connected with airborne vehicle has guide cables attached to it. Upper and lower mating flanges with mounting holes are installed on each section on the upper and lower end correspondingly. Upper mating flanges are made with rigid cone catches of accurate setting, and lower flanges - with inlet channels. Before lifting the guide, cables are attached to the mounting holes of lower flanges. During airborne vehicle hanging, for instance, helicopter, guide cables are put through mounting holes of upper flanges of earlier installed section. When the airborne vehicle goes down, guide cables are pulled from below with force corresponding section mass before aligning of inlet channels of lower flanges of section being mounted with rigid cone catches of accurate setting of upper flanges of earlier installed section.

EFFECT: increase of accuracy and safety of sections installation.
