摘要

Mobile rope transport is an effective means for the rapid organization and implementation of transport and logistics operations in hard-to-reach territories with difficult relief or in the absence of the necessary transport infrastructure. Mobile ropeways based on self-propelled chassis with high load capacity and cross-country capability have the greatest autonomy for carrying out these works. Currently, this type of rope transport is relatively new and therefore insufficiently studied. The chapter presents the results of modeling the operation of a carrying-traction rope system of such ropeways based on its traction calculation, which made it possible to identify and analyze the key technical characteristics and operability conditions of this type of rope transport. It was found that the functionality of single-span mobile ropeways is quantitatively determined by the spatial-weight characteristics in the three-dimensional space of the parameters “span – inclination angle – cargo weight”. The configuration and quantitative parameters of the zones of possible use of mobile ropeways in the specified parameter space are determined by a mutual combination of parameters such as the traction factor of the drive rope pulley, the permissible pressure of its lining material, the end tower length, the maximum design bending moment in the tower root section, the drive mechanism power, the drive pulley diameter, the diameter and tensile strength of the carrying-traction rope. Based on the analysis of these parameters influence, practical design and operational measures have been developed that make it possible to effectively manage the operational capabilities of single-span ropeways, taking into account the real operation conditions. It is shown that the ropeways allow carrying out transport operations in the range of inclination angles up to 60 degrees within spans up to 760 m. The chapter will be of interest to researchers and production specialists in the field of design and operation of mobile transport rope systems.
