Designing Supporting Structures of Passenger Ropeways of Minimum Cost Based on Modular Intermediate Towers of Discretely Variable Height

Abstract

Passenger ropeways are a promising alternative for the development of public transport infrastructure in large cities. However, the construction of ropeways has a rather high cost and requires taking into account a significant number of restrictions associated with the features of the existing urban development and the placement of urban infrastructure. The main objective of this research is to develop optimization models that minimize the total cost of modular intermediate towers of a discretely variable height and a rope system due to the optimal placement and selection of the height of these towers, taking into account the features of the surface topography and urban development. The proposed modular principle for the construction of intermediate towers also enables the cost of construction to be further reduced. As a specific example, the design of a ropeway in the city of Bryansk, which has a complex terrain, is considered. The developed models are conveniently used at the initial stage of the design of the ropeway to compare the cost of various options for the location of the ropeway route in order to reduce the risk of error when choosing the least expensive option. The calculation results can serve as a guide for a preliminary assessment of the number and height of intermediate towers, their installation locations on the ground and the characteristics of the cable system.

Possible Ways of Evaluation of Industrially Manufactured Means for Low-Bearing Terrain Strengthening Usable in Military Operations

“…However, these types of research do not address the possibility of terrain modification by means for low-bearing terrain strengthening, but they focus on calculations related to current terrain conditions. There are also many articles dealing with calculations in transportation [12], [14]. However, the authors of this article did not find materials that would comprehensively address the issue evaluation of industrially manufactured means for low-bearing terrain strengthening using mathematical models for technical indicators assessment and costs calculation, representing this research's aim.…”

Optimal planning of the mobile cargo ropeway repair strategy

“…2b). To coordinate the mutual inclination of the rope pulleys of the conjugate transport units, which is caused by the natural sagging of the carrying-traction rope and the location of the units at different heights [24], a hydraulic rope pulley orientation mechanism is used.…”

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

“…Currently, mobile aerial ropeways should be considered as a promising type of overhead transport [1]. This is especially true in relation to the conditions of their use in unequipped and hard-to-reach territories with difficult terrain or unfavorable physical and mechanical properties of the surface soil.…”

“…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].…”
