Abstract: The article substantiates the type of front suspension for robotic mining dump trucks with a load capacity of up to 90 tons. The development relevance conclusion of quarry dump trucks is made. Each type of front suspension used on existing mining dump trucks is considered. It is established that the most popular type of front suspension is single-lever transverse. For the analysis of suspension types by performance characteristics, the method of multicriteria analysis – TOPSIS was used. The initial data for choosing the type of front suspension by the TOPSIS method is a decision matrix, which includes estimates of alternatives by criteria, as well as weights of criteria. The alternatives in this case are the types of front suspension, and the criteria are performance indicators. According to the TOPSIS method, the coefficients of approximation of each variant to the ideal were determined, which are graphically represented on the histogram. As a result of the analysis, it was found that the independent, single-lever transverse (MacPherson) front suspension used on most dump trucks with a load capacity from 60 to 110 tons most fully corresponds to the operational indicators.
