Providing the vertical dimension of a self-propelled machine with a rod mechanism for install-ing and fixing the end tower for a mobile ropeway

Abstract

Mobile ropeways for carrying out loading and unloading and transport and transfer operations in previously unsettled or inaccessible areas, formed with the help of terminal base stations connected by a single rope system on the basis of self-propelled wheeled or tracked chassis of increased carrying capacity and cross-country ability, are a promising type of lifting and transport equipment ensuring the prompt deployment of the necessary technological tools. The article deals with the layout of the mechanism for installing and fixing the end tower using a folding bar, consisting of two articulated links. A mathematical model has been developed that provides the required normative vertical dimension of a self-propelled base station of a mobile ropeway with the aim of its safe independent movement to the place of deployment of the ropeway along general roads. The analysis of the influence of standard dimensional requirements, design dimensions of the chassis carrying frame and the height of the end tower on the main design dimensions of the articulated folding rod in the transport position is carried out. Calculations have shown that the considered design makes it possible to provide the standard vertical dimension of a base station on a 6-axle self-propelled chassis with an end tower length of up to 18 m.
