Selection of a semi-trailer for the haulage of long oversize loads, taking into account an analysis of operational damage

The use of different types of semi-trailers for transporting oversized cargoes makes it possible to increase the competitiveness and transport potential of transport companies. Improper selection of semi-trailers and the use of universal protection systems affect the durability and safety of the use of means of transport. The results are presented of an analysis of damage caused to semi-trailers transporting long oversize loads due to incorrect operation. The reasons for the occurrence of damage and errors made during operation, which directly contribute to the occurrence of destructive phenomena, are discussed. The decision-making problem of choosing the right means of transport for the task of transporting long oversize loads has been solved based on an example of haulage of pipes. The study used a multi-criteria method. The results of the conducted analyses and tests show that damage occurs only to standard curtain-sided semi-trailers, in which it is the rear section that suffers damage. The solution to the decision-making problem of selecting the semi-trailer using multi-criteria methods shows that extendable semi-trailers are definitely the best choice for transporting long oversize loads.
