金层芯起重钢绳(多层钢绳)的使用效率取决于它的结构型式,这种钢绳使用上所发现的缺点是绳股膨胀,金属芯断裂或露到钢绳表面等等。这都是由于其构件变形,破坏了协调性的结果,从而使钢绳中积聚不可逆的结构变形。这首先是由于多层钢绳对扭转的反应非常敏感。而扭转在很多情况下,在使用过程中是必然要发生的,并且会引起负荷不利的重新分配。
The efficiency of use of the gold layer core lifting rope (multi-layer steel rope) depends on its structure type. The shortcomings found in the use of this steel rope are that the rope is expanded, the core is broken or exposed to the surface of the rope, and the like. This is due to the deformation of its components, undermining the coordination of the results, so that irreversible accumulation of structural deformation in the steel cord. This is primarily due to the fact that multi-layered steel ropes are very sensitive to torsion. Torsion, in many cases, is inevitable during use and can cause unfavorable redistribution of loads.
