由于钢丝绳的结构、性能复杂而且不同的使用场合有不同的要求,若选用不当,不但不能发挥某种钢丝绳的特定性能,而且将得到相反的结果。以往金属矿山的竖井和斜井提升多选用普通圆股钢丝绳,竖井多选用6股19丝和6股37丝,斜井多选用6股7丝。但这些钢丝绳的使用寿命都较短,一般为6～7个月,很不经 Due to the structure of the rope, complex performance and different applications have different requirements, if not properly selected, not only can not play a specific rope performance, and will get the opposite result. Previous metal mine shaft and inclined shaft to enhance the use of more common selection of round wire ropes, shafts and more use of 6 19-wire and 6 37 wire, inclined shaft and more use of 6 7 wire. However, the service life of these ropes are shorter, usually 6 to 7 months, it is not without
