Today, one of the main conditions for the rapid development of the machine-building industry in our republic is technical modernization, or in other words, the introduction of new techniques and technologies based on the achievements of scientific and technical development into the production processes of machine-building.  In our republic, comprehensive measures are being taken to increase the volume of road construction, construction, and excavation works in mining, to reduce the material and energy costs of production, and to effectively use widely used technical means, and certain results are being achieved. Currently, in the development of production, there is a way to use powerful mobile equipment that can perform several operations at the same time. We can give an example of new cars produced in Andijan, Tashkent and Samarkand. This, in turn, increases the demand for long-term operation of machines without breaking down. Therefore, the quality and reliability of new and refurbished cars are becoming more important today.
