Impact of design capacity on optimal parameters of freight aerial mono-cable cableways

Abstract

Abstract 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.
