Trends in the development of unmanned mining dump trucks

Abstract

The article presents the trends in the development of the dump body of mining dump trucks, identified during patent research for the project entitled “Development and creation of an unmanned shuttle-type mine truck with a payload of 220 tons”. The analysis of patents was carried out on the dynamics of patenting, its geography and patent holders. The depth of the patent search was 25 years. Based on the results of analyzing the identified patents, a forecast was made on the development of technical solutions for the dump body of mining dump trucks. It was found that: the dump body designs have been actively patented since 2013; the USA is the leader among the patent holders; the main trend in the development of the mining dump truck designs is caused by the need to cut down the specific metal content, as well as to reduce wear and sticking; since 2014, there has been a stable interest in patenting linings; 51% of the total patent base obtained belongs to 5 major global companies that manufacture dump trucks and 3 enterprises that produce equipment for mining machines. The identified technical solutions will allow evaluating the existing layout and design solutions, and developing new solutions by modeling in the discrete-body dynamics and the solid-body dynamics environments to calculate the stress-and-strain state of dump body for mining dump trucks.
