Abstract: In the article the designs of universal loading platforms for the main open-pit dump trucks with payload capacity of about 90 tons which are used in Russia – BelAZ 7558/7557, CAT 777E, Komatsu HD785 – are considered. The criteria of rational loading platform, universal loading platform are defined and set, the rational loading platform usage is justified. Service purposes of different platform elements and rules of their operation, method of production and transportation by parts are described. The basic design features and schematic solutions of the considered loading platforms are also described. Some technical characteristics and properties of construction materials are presented, and the manufacturer's parameters are compared for dump trucks of the same class and with the same tire size. On this basis, the features and common features of each of the considered designs of loading platforms are revealed. The dependence of loading capacity of dump truck on the weight of the loading platform is defined. The results obtained in the analysis can help in choosing a loading platform for a dump truck or in designing new loading platforms. Based on the analysis of the considered loading platforms in the future it is planned to form a methodology and criteria for assessing their effectiveness, which can help to increase the productivity of transportation in open-pit mining.
