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

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.

Reducing labor intensity when computing optimal technical characteristics of aerial ropeways

“…The issues of identifying most appropriate technical characteristics of ropeways based on the need to minimize construction costs, have not yet been studied. Such topics are discussed, for example, in [22][23][24].…”

Optimal planning of the mobile cargo ropeway repair strategy

“…The scope of effective application of mobile rope systems is quite wide and diverse. It is advisable to use them when performing construction and mounting work at autonomous remote facilities, eliminating the consequences of natural or man-made emergencies [4], mining and extractive industries [5,6], performing forestry work in mountainous or hard-to-reach areas [7,8], performing loading and unloading operations [9], etc.…”

Modeling the Reliability Indicators' Kinetics of a Mobile Ropeway Formed by the Self-Propelled Units

“…Such rope transport systems are effective for use in the ecosystems that are most vulnerable to negative anthropogenic impacts -forest, mountain alpine and Arctic territories [2][3]. Mobile ropeways also have advantages when it is necessary to provide the minimum terms of carrying out preparatory works for the commissioning of transport and transshipment technological operations [1,4]. Mobile rope transport systems are an important addition to stationary aerial ropeways, which have proven themselves as transport and logistics systems for cargo transportation and passenger traffic in urban and suburban conditions [5].…”

“…The carrying-traction rope movement mechanism of one of the mobile units provides a pendulum movement of the transported goods along the route of the ropeway. The carryingtraction rope tension mechanism of another mobile unit ensures its optimal tension [4]. These mechanisms have a frequency-controlled hydraulic drive.…”
