Parallel laid, with a large metallic cross-section, high breaking load relative to the ropediameter.
线接触结构，金属面积比较高，具有较高的破断载荷。
2
When the breaking amount of wire in the 10 times of the wire ropediameter has surpassed 5%, you should change the wire rope.
当钢丝绳上的10倍直径长度范围内断丝根数大于总数的5%时，必须更换钢丝绳。

Through the actual calculation, the different diameter needed by the rope has been obtained. Comparison with the two traditional design methods, the fatigue reliability design is more practical.
