Freight aerial cable roads are an efficient mode of transport in mining industry. The purpose of the paper is to develop the method of optimal design of a mono-cable freight ropeway thus reducing the cost of its construction. It is shown that the pitch and height of intermediate supports, the tension force of load-carrying-traction ropes exerts the main influence on the cableway cost. The problem of conditional nonlinear optimization of the mentioned factors ensuring the minimum cost of a cableway at different design capacity up to 600 t/h is formulated and solved. The optimization task is solved taking into account the necessary design, assembly, deformation and strength limitations. Regularities of change of optimal parameters of intermediate supports and load-carrying and traction ropes at the change of design capacity of a cableway were revealed on the basis of analysis of performed calculations. The results of this optimization task allows significantly reducing the cost of construction of freight aerial cableways.
