Productivity of cargo mobile ropeways based on coupled mobile transport and overloading rope complexes

Abstract

Single-span mobile pendulum-type ropeways formed by two coupled self-propelled wheeled chassis of high load capacity and cross-country capability are a promising type of transport and reloading equipment under difficult operating conditions. This article discusses the problem of assessing the weight productivity of such mobile ropeways under various technological options and modes of their operation. A computational method for determining the productivity within the area of the possible use of mobile ropeways is presented, characterized by the magnitude of the span and the angle of inclination of the line of the carrying-traction rope between the terminal points of the route, as well as the weight of the transported cargo. It is shown that the weight productivity significantly depends on the duration of loading and reloading operations and therefore is a variable characteristic of a mobile ropeway, depending on the specific operating conditions (used lifting and rigging equipment, the qualifications of the service personnel, the weight and configuration of the transported cargo, the availability of storage sites, etc.).
