  • Analysis and development of an emergency rescue tool

    The article considers the analysis of a manual mechanized tool for rescuing victims from rubble and traffic accidents. The statistics provided by the GUOBDD of the Ministry of Internal Affairs of Russia are given, where traffic accidents in Tyumen and the Tyumen region are displayed. The advantages and disadvantages of a mechanized rescue tool are described. A study was carried out on the modernization of rescue tools, a design for reverse sharpening of the cutting element of hand shears was proposed to prevent bending and jamming of the metal.

    Keywords: power tool, hand tool, emergency, traffic accident, research

  • Design of articulated pneumatic roller for construction of winter highways

    In the Russian Federation, there are settlements that can only be reached by special equipment: swamp walkers, SUVs. Permanent access to such settlements is hindered by swamps, rivers, etc. Temporary winter roads "autozymniki" are laid to such settlements in winter. The construction of "autozymers" includes several stages: the preparatory stage, the main stage of construction, operation of the autozymer and disposal. If a temporary winter road passes through swamps, then it is advisable to push such soils with tractors with widened tracks or tracked tractors. The article proposes the design of a articulated pneumatic roller for the construction of winter highways, and also carried out a design calculation including: calculation of resistance to movement, hydraulic calculation, selection of hydraulic equipment.

  • Overview of structures and design of a mobile pellet production plant

    The article discusses the production and use of environmentally friendly fuel - pellets. A review of the designs of mobile pellet production plants was carried out, the advantages and disadvantages of these designs were identified. Potential consumers of pellets and equipment (heating boilers for which pellets are the fuel) are considered. A mobile complex for the production of pellets on the chassis of the MSN-10-004-03 . The technology of pellet production using a mobile mobile installation is described.

  • The layout of the combined machine based on the KamAZ vehicle

    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. The article considers the configuration of components and assemblies of a modernized machine for the construction of winter roads based on KamAZ, as well as a calculation of the power balance.
