Semi-trailer Selection Method

Abstract

The purpose of the study is to form a comprehensive methodology for selecting a semi-trailer as one of the main elements of the fleet, which will ensure the minimization of logistics costs, increase the productivity of the enterprise and safety of transportation, through a systematic analysis of the technical, economic and operational parameters of vehicles in accordance with the specifics of cargo flows and conditions of the region of operation.

The article analyzes the semi-trailer market and scientific publications for the period 2020-2025. Factors influencing the choice of a semi-trailer are grouped into the following categories: cargo specifics, design parameters, body specialization, economic feasibility and secondary market risks. A detailed study of the influence of the physical properties of cargo on the choice of body volume was conducted. The technical components of the chassis were analyzed, in particular the advantages of air suspension over spring suspension and the choice between steel and aluminum frames. Particular attention was paid to the functional capabilities of various types of bodies: from universal tented models and moving floor systems to specialized container trucks. The adaptation of equipment to the difficult climatic and geographical conditions of the region in which operation is planned is considered, including requirements for heat resistance and cross-country ability. A separate block highlights the issues of purchasing used equipment, where critical risks are identified: hidden defects in frame geometry, wear of brake systems, and legal aspects of documentary support.

It has been proven that effective selection of a semi-trailer is possible only with an individual approach that takes into account compatibility with the tractor and specific logistical tasks, and a rationally selected design allows you to significantly reduce operating costs, increase payload and extend the service life.
