Some results of studying the operational reliability of heavy-duty dump trucks in severe climatic conditions
Abstract
The study of operational reliability of heavy-duty dump trucks BelAZ-540 and BelAZ-548A was carried out in extremely difficult natural and climatic conditions of apatite mine “Tsentralny”, located in the center of Khibiny at an altitude of 1000 m above sea level. Reliability analysis was performed on the basis of data for 1970-1971. Only relatively serious failures of vehicles, which required at least two hours for their elimination (including the time for fault detection, dump truck travel to the repair shop and the time of all operations related to repair), are taken into account, since there is practically no information on smaller failures.
