提高露天矿汽车运输生产率和技术经济指标的主要措施是加大自卸汽车载重量和汽车发动机的比功率,提高主要部件和总成的可靠性。为实现露天铁矿运输总量的增长,可以用增加-549和-7519型自卸汽车台数以及使用-7521型自卸汽车的方法来解决。预计到1990年,露天铁矿自卸汽车的平均载重量将从54吨增至70吨。生产试验表明,苏联大型自卸汽车的多数技术参数和经济指标并不差于外国同类较
The main measures to increase the productivity and technical and economic indicators of the open-pit car transport are to increase the load capacity of the dump truck and the specific power of the engine of the automobile so as to improve the reliability of the main components and the assembly. In order to increase the total amount of open-pit iron ore transportation, it can be solved by increasing the number of dump trucks-549 and-7519 and using the -7521 dump truck. It is estimated that by 1990, the average load capacity of open-pit iron dump trucks will be increased from 54 tons to 70 tons. Production tests show that the majority of the Soviet Union’s major dump truck technical parameters and economic indicators are not worse than foreign similar
