Abstract: The article is devoted to the collection of experimental data during the operation of quarry dump trucks to further determine the load of the main components of rigid-frame dump trucks. The relevance of collecting experimental data on the operation of dump trucks in real-world conditions is noted. The list of necessary data for collection is presented (information on the speed and position of the dump truck in the quarry, suspension movements, operating mode of the power plant and transmission, steering position, driver's influence on the controls). The structure of the data collection system has been developed. The list of components of the data collection system that dump trucks should be equipped with is given, indicating the location of the main components of the data collection system on a quarry dump truck. The authors note that the collection of experimental data should be preceded by a stage of control races, the main task of which is to control the correctness and approval of the data obtained. Based on the results of successful completion of a series of control races and approval of the results, the main series of experimental races should be conducted. The results of the main series of experimental races are flat and spatial test maps, a map of all recorded routes. Due to the significant amount of data received, it is necessary to process it for the possibility of analysis and subsequent work with signals. In conclusion, it is noted that the recorded data make it possible to implement the author's method of calculating the load of mining dump truck components in order to analyze ways to increase the life of the undercarriage and load-bearing system of a mining dump truck, and should also potentially allow obtaining data on the micro- and macro-profile of quarry roads; in the time history and amplitude-frequency characteristics of sprung and unsprung parts. dump trucks; average data on the operational characteristics of mountain roads in the section (average and maximum angles of ascent and descent, the number of loading and unloading flights, the number of runs without and with cargo, the intensity of dump truck loading, and much more).
