This article addresses the issue of whether to use balloon-cable transport systems during the development of hard-to-forests of the Far East region. Brief description of the balloon trans-port facilities is given from which the need for research efforts in emerging trailer return fila-ments is visible, presented with synthetic ropes. The technique of calculating the spatial tension of ropes with some effort in the filaments at the location of the point of suspension over any part of the operational site is given. Conclusions are made, determining the possi-bilities of the proposed method of calculation.
air transport of wood, rope tension, balloon-cable system, approximation of the terrain, wind load.
