The materials of the article are devoted to the issue of simulation modeling of construction mechanized technological equipment, in particular, modeling of the lifting and assembly module for the installation of a structural coating. Today, an urgent task in the construction market is the construction of large-scale structures, the life cycle of which is shortened, but the construction terms are reduced. Such a need exists in the construction of shelter hangars, field hospitals, warehouses, etc. As a rule, for urgent needs, buildings with light construction structures are erected, the covering of which is formed by structural blocks. A feature of such structures is multi-element support elements. A lifting assembly module is proposed for the installation of such structures. It is essential that the mounted structural coating is assembled on the heads of the lifting and collecting modules in blocks, and the lifting of the structural block to the design mark occurs thanks to the module while simultaneously raising/assembling the supporting elements of the coating. Simulation computer modeling tools were used to study the possibility of implementing the assembly process using the lifting assembly module. It is proposed to use the parametric formation of sketches and 3D models when forming the design features of the module. The dissection of the elements of the new assembly module, support elements and structural coating to the level of simple parts made it possible to determine their mass characteristics with sufficient accuracy. The basic technical indicators of the assembly module and building structures, which can be used in the development of the assembly technology, were obtained. Approaches to the use of cloud databases when using unified elements during design are defined.The use of simulated geometric modeling data allows to analyze the strength properties of the components of the technical system and, together with the visual observation data, to create a common information model of the building object with the possibility of qualitative analysis of the indicators of the specified elements of building structures.

High-speed working units are very widely used in modern construction, in the destruction of durable materials and soils and more. When calculating the power and energy parameters of dynamic working units take into account changes in the nature of the interaction of the cutting element with the environment and the emergence and propagation of soil stresses from the action on the boundary of the array of the cutting element. This leads to the emergence of a stress-strain state in the soil mass, which has an oscillatory-wave character. The nature of the stress-strain state is influenced by the state of the working environment and the speed of cutting (destruction) of the soil mass. An unsolved problem in the dynamic destruction of soils is to take into account the kinematic features and technology of work with high-speed peripheral and front-end working units. The design parameters of these working units must take into account not only the dynamic parameters of the fracture process, but also the phenomenon of accumulation of fatigue deformations in the working environment.

Single-bucket front loaders are usedwidelyin road construction. In some cases, their use is more rational than traditional digging and earth-moving machines.Front loaders have a high-er bucket capacity per unit weight, high maneuver-ability and lower operating costs compared to sin-gle-bucket excavators. This allowsyou to develop grounds in small bottoms without compromising productivity.Improvement of the loader use effectiveness throughout the year can be achieved by armory it with replaceable working equipment.The existent working equipment range contains buckets for various purposes (main, reduced, enlarged, with forced unloading, frame, two-jaw, with side un-loading,etc.).The bucket design with side unloading, calcula-tion of its main parameters and control system are presented in paper.The loader with such replacea-ble working equipment can be used in construction during loading and unloading operations, in the mining industry, and as mechanized detachments part of the Ministry of Emergency Situations dur-ing emergency recovery operations.

The article considers an approach to determining the labor-intensiveness and duration of consolidation processes during the installation of structural blocks of the covering, which is caused by atypical structural and technological solutions. The relevance of this work is the need for a qualitative analysis of methods for calculating the labor intensity and duration of technological processes when justifying and making decisions regarding the organization and mechanization of assembly processes. Modern technologies of installation of structural blocks of coatings are analyzed. The analysis of labor costs was carried out for the option of using load-lifting assembly modules to reduce the specific share of the use of heavy crane equipment at the construction site. In comparison, the method of installing a structural coating using heavy crane equipment and load-lifting assembly modules is considered. To ensure the principle of comparison of options, the processes of column installation, stand installation, block consolidation, block installation, and installation and movement of a crane or assembly lifting and gathering modules are included in the consideration. All calculations were performed in tabular form according to the formula of the integer normalization method. Based on the results of the study, all the components of the labor intensity and duration of the processes were determined, on the basis of which the schedules of the consolidation and installation of the SBP blocks were built.

The results of the research on road surface cleaning in the winter period are presented. Among the most time-consuming are works to ensure the passability and safety of road traffic in the winter period. They account for a significant part of road maintenance labor costs. At the current stage of the development of equipment designed for the destruction of snow-covered formations, it is possible to divide the devices according to several characteristics: manual devices and tools, according to the principle of action of the working body on the environment - mechanical, ultrasonic, thermal and thermodynamic. The snow cover is treated with reagents that prevent the compaction of snow by the wheels of motor vehicles and preserve its loose properties, and then, depending on the width of the road surface of the one-sided lane, several plow-brush snow plows are included in the work. Plow-brush snow plows have a productivity of 1500...7500 m3/h, rotary snow plows provide a productivity of 500...1375 t/h. To remove ice, mechanical working bodies of shock action are most often used, the working elements of which are in direct contact with the working environment. In general, they can be divided according to the nature of the energy used: vibration, scraping, milling, brushing, combined. The proposed equipment for cleaning roads from ice is attached to the base machine, its feature is that the design of its chipping knives allows not to destroy the road surface during operation.
