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. On each section there installed are upper and lower coupling brackets with lower coupling brackets performed with rigid safety catches of accurate setting, and upper coupling brackets - with bellmouths. Guide cables are attached to the lower coupling bracket holes before lifting of each section by airborne vehicle, during airborne vehicle hanging when mounting, for instance helicopter, guide cables are put through the holes of upper coupling brackets of earlier installed section. When the airborne vehicle goes down the looseness of guide cables is chosen manually. As a result bellmouths of upper coupling brackets on mounted section are jointed with rigid safety catches of accurate setting of lower coupling brackets on the section being installed.

EFFECT: increase of accuracy and safety of sections installation.
