The two-belt guy system is equipped with two additional pairs of directed in opposite directions non-stationary rollers and the central support four-part drum, through the two upper parts of this one the upper bearing and the lower stabilizing belts of the continuous two-belt closed guy go. The upper belt goes linearly, and the lower one - in loop-like way, with surrounding in the places of inner bend two pairs of rigidly and in pairs fixed at above and at beneath on the central support four-part drum inner stationary rollers, between those in the middle part of the drum three pairs of directed in opposite directions inner non-stationary rollers are placed, with formation of single-span two-section closed two-belt -like guy system.
