在独联体各国中,顿涅茨克矿山机械生产联合公司是唯一研制和生产提升能力达630kN的矿井多绳提升机的企业。从1957到1992年期间,共生产了440台多绳提升机。多绳提升机的计算使用期限最初取15年,后来取20年,而近几年来延长到25年,或者连续工作10万小时。根据统计,目前使用期超过20年并在继续运行的多绳提升机有154台(占总台数的35％),使用期超过15年的94台(21％)。由此可见,154台多绳提升机的计算潜能已经耗尽,在最近4
Among the CIS countries, Shakhtar Donetsk Mining Machinery Joint Production Company is the only company that develops and produces mine multi-rope hoists with a capacity of 630kN. From 1957 to 1992, a total of 440 multi-rope hoists were produced. The calculation of multi-rope hoist lifespan first taken 15 years, then take 20 years, and in recent years extended to 25 years, or continuous work 100,000 hours. According to statistics, there are 154 multi-rope hoists (35% of the total) that have been in use for more than 20 years and are on stream and 94 (21%) with a service life of over 15 years. Thus it can be seen that the computational potential of 154 multi-rope elevators has been exhausted in the recent 4 years
