A multinational documentary standard that regulating indices and classification procedure of road tunnels has been developed. For the purpose of the most effective construction of classified subjects in transport infrastructure there are number of problems which based on creating a link between road tunnels technical characteristics by cut diameter, mining-geological condition and mining machines structure. This article covers solutions which are necessary for science based approach to better engineering solution for heading machines in road tunneling. One of these solutions is the development and a practical implementation of modular configuration methodology. A main idea of the solution is based on using complete assembly units which are being serially produced by a production plant. A modular configuration of loading machines and overloaders are based on hydroficated units of tunneling machines reviewed in this article. During listed solutions development the usage experience of the best reliability equipment in tunneling industry has been taken into account. Creation of next technical level machines with unified modular assembly units will allow to raise their performance rating, compatibility also it suppose to short assembly units list, prime cost decrease and also lower the number of warranty service spare parts.

  Results of investigation into oscillating pattern of garbage track operation in production mode are presented. Nature of car frame vibrations, lifting angle of handler and their impact on generation of force inside the system «grabbing device – container – grabbing device» subject to damping are determined.
