由于多绳提升机具有设备重量轻、易于制造、电耗小、安全性好等多方面的优点,所以近年来在国内大中型矿山的设计中,得到了广泛的采用。多绳提升机所用的井塔,比单绳提升机所用的井架费用高,基建时间长,而且卷扬机安装和井塔施工不能同时进行,往往因此加长了基建时间,这是多绳提升机存在的缺点。 Multi-rope hoist has the advantages of light weight, easy to manufacture, low power consumption, good safety and so on, so it has been widely adopted in the design of domestic large and medium-sized mines in recent years. Multi-rope hoists used in the tower, single derrick than single-hoist used in high cost, long infrastructure, and hoist installation and construction of the tower can not be carried out at the same time, often thus lengthening the infrastructure time, which is multi-rope hoist exist Disadvantages.
