Abstract: This article presents the results of patent studies of the load-bearing systems (frames) of mining dump trucks. An analysis of the distribution of published patent documents by years of filing applications and geography of patenting was carried out, the main technical solutions were identified, leading applicants and patent holders were considered. Patents for the last 25 years have been reviewed as part of patent research. The inventive activity is unevenly distributed, since 2006 the interest to patenting of the supporting system (frame) and its elements is increasing, which is confirmed by a stable increase in the number of patent documents. The dynamics of distribution of patent documents on the load-bearing system (frame) of dump trucks by years of publication shows the alternation of ups and downs of publication activity. About 77% of the identified patent documents are directly related to the load-bearing systems (frames) of dump trucks, the remaining 23% are related to crossbars, over-frames, bumpers, spars and sub-frames. There is an increasing interest in the analyzed area of patent search for the last 17 years, Chinese and Russian applicants and patent holders are leading in this area. Development of new technical solutions is aimed at improving the efficiency of the dump truck and is associated with the need to eliminate the identified deficiencies and to improve the strength and reliability of the elements of the load-bearing system (frame), found during the operation of dump trucks.

Key words: mining dump truck carrier system (frame) carrier system elements (frames) patent research patent documents
