Evaluation of the influence of the longitudinal slope of carriage roads on the tire life

Abstract

This article presents an analysis of the results of an experiment conducted in the Muruntau quarry. All routes are divided into 5 groups depending on the average slope of the road. For the first group, routes with an average road slope from −1 to +1% were chosen; for the second group, with an average road slope from 1 to 3%; for the third, from 3 to 5%; for the fourth, from 5 to 7%; fifth more than 7%. The experiments were carried out on Komatsu HD785-7 dump trucks with a carrying capacity of 91 tons. According to the results of the experiment, it was found that the life of dump truck tires operated on routes with an average road slope of 6% is reduced by 2 times compared to tires operated on a horizontal road.
