The construction of winter roads in the Russian Federation is determined by the geographical location and climatic features. Most of the territories are located in unfavorable climatic zones, and there are also settlements, accessibility to which can be realized by means of temporary roads. The process of erecting such engineering structures is expensive and labor-intensive. In order to reduce costs, it is necessary to modernize technologies and ground transport and technological facilities. The proposed combined machine based on the KamAZ vehicle is a technical solution that allows to reduce the time and cost of building winter roads.

Abstract: Operation of motor transport and special equipment is carried out in difficult conditions, the impact of environmental conditions (temperature, humidity, dust, wind, solar radiation) and changes in modes of operation of the machine. This affects the performance of equipment, the number and complexity of repairs. Away from fixed bases (in the field), the problem is particularly acute repairs. One of the most energy-intensive and expensive works are welding (welding parts with a break, welding cracks, fusing metal layer on the worn surface, metal cutting). In this work the welding equipment affect the voltage drops in the supply mains, therefore, produces a large number of failures such equipment. After the equipment is accompanied by an increased amount of electric power consumption, this results in material costs. Previously proposed equipment has improved mass, which reduces the efficiency of the welding. Based on this study was proposed innovative design welding inverter using the resonance effect, with enhanced reliability, low-cost design version (in terms of mass production). In order to improve the reliability and reduce the cost of the proposed design of inverter proposed a number of new approaches. Full-bridge inverter is studied welding power source with the implementation of the resonance effect with a stable and smooth operation, high reliability, because the circuit of the inverter is not sensitive to changes in the supply voltage.
