The two-belt guy system has two-belt closed guy with links resting in the places of bend on stationary rollers fixed on support elements, between those non-stationary rollers are placed with possibility of displacement in horizontal plane. It includes two additional two-belt closed O-like guys with rollers and links with formation of one-span guy system with three sections with permanent or varying length; at that the outer support elements of the end sections are additionally equipped with two more pairs of directed in opposite directions non-stationary rollers, through those continuous closed guys go, those are combined at two support, placed at the ends of the central section, III-like units with telescopic running section of the end and/or central vertical rods, and it includes four pairs of additional inner stationary rollers with formation of symmetrical closed O-III-O-III-O-like contour; at that the inner part of the III - like units is equipped with spherical elements as closed balls with constant or varying radius rigidly fixed in the middle part of the end and / or the central vertical rods; besides that fixation of the guys of each of three sections is arranged at the outer side of each spherical element.
