Abstract
The relevance of the processes of processing construction waste into secondary raw ma-terials will only increase over the years due to the increasing number of outdated or destroyed buildings that are not suitable for further operation. The processing of concrete into secondary crushed stone includes such processes as separation, sorting and grinding, which are performed directly at the places of construction waste generation. For their implementation, it is necessary to deliver specialized mobile crushing and sorting plants, which belong to large-sized and heavy equipment. Special technical means for oversized and heavy loads are used to transport mobile crushing and sorting plants, as well as other specialized equipment. The most suitable means for transporting such cargoes are trailed vehicles, namely trawls. Trawlers are manu-factured in the form of trailers or semi-trailers, which differ in the number of axles, load capacity class, height and method of loading, type of suspension, etc. In the work, an overview of the existing designs of trailer vehicles for the transportation of large-sized and heavy loads was performed, and their parameters were analyzed. According to the obtained results, it was determined that within the same load capacity class, trawls differ in terms of total weight, platform length, loading height, metal capacity of the structure and other parameters. The advantages and disadvantages of various layout schemes of road trains (tractor and trailer) are determined. Knowledge of the constructions of these vehicles, their parameters and operational features allows you to make a choice in accordance with the conditions of transportation, characteristics of the cargo, the distance of transportation and routes.
