The guy system that includes a two-belt closed guy with the links and the upper bearing and the lower stabilizing belts resting in the bending places on stationary rollers fixed at the outer support elements, between those two non-stationary rollers are placed with possibility of displacement along horizontal axis. It is equipped with four additional directed in opposite directions outer non-stationary rollers and two four-step drums, the vertical axis of symmetry of those is separated from the ends of the span by one-third of its value, and through the two upper parts of each drum the upper bearing and the lower stabilizing belts of the closed guy go; at that the upper belt goes linearly, and the lower one - twice loop-like, with going round the rigidly and in pairs fixed at each of the drums two pairs of the inner stationary rollers, between those three pairs of directed in opposite directions inner non-stationary rollers are placed, with formation of one-span three-section closed two-belt -like guy system surrounding four outer stationary rollers that are rigidly fixed at the outer support elements, between those three pairs of outer non-stationary rollers are placed with possibility of displacement in horizontal plane.
