8×31WS+FC 是 8 股 ×31 丝（瓦林吞 - 西鲁复合结构）+ 纤维芯 的线接触钢丝绳，主打高柔韧性与耐疲劳性，符合 GB/T 20118-2017《钢丝绳通用技术条件》、EN 12385-4 标准，适用于中型起重机、建筑卷扬机、港口辅助装卸、矿山斜井运输等中重载且需频繁弯曲的工况。
一、基础结构参数
参数项 详细说明 结构组成 8 个外层股 + 纤维芯（FC，材质多为聚丙烯或剑麻）；每股 31 丝，采用瓦林吞 - 西鲁（WS）复合排列（1-6-12-12 分层，粗细钢丝交替分布），股绳表面光滑，接触应力均匀 钢丝材质 优质碳素结构钢（#60、#70、#72A），冷拔强化处理；表面可选光面、热镀锌、电镀锌 表面处理 光面：干燥无尘工况；热镀锌：厚锌层，适用于潮湿 / 户外 / 轻度腐蚀环境；电镀锌：薄镀层，装饰性防锈 直径范围 常见 16~52mm，主流应用 22~44mm 中重载提升场景 公称抗拉强度 1570MPa、1770MPa、1960MPa（工业常用 1770MPa 等级） 捻向 右同向捻（RHRL）、左同向捻（LHLL）、右交互捻（RHRH）；8 股对称结构抗旋转性优于 6 股绳 重量系数 0.370~0.390（FC 芯参考值，镀锌后重量增加 3%~5%） 最小破断拉力系数 0.335~0.350（比同结构 IWRC 芯低 10%~12%） 二、典型力学性能（节选，FC 芯，1770MPa）
公称直径（mm） 参考重量（kg/100m） 最小破断拉力（kN） 适用场景 20 148 198 建筑卷扬机、小型起重机副钩 28 290 390 港口龙门吊副钩、矿山斜井辅助运输 36 488 695 中型履带吊副钩、风电塔筒辅助吊装 44 728 1030 港口卸船机辅助牵引、盾构机配套卷扬 50 938 1290 大型起重机辅助钩、建材吊装设备 注：抗拉强度提升至 1960MPa 时，破断拉力约增加 11%~13%；热镀锌处理后破断拉力略有下降（约 1%~2%）；纤维芯需定期润滑防潮，避免腐烂失效。三、核心特性
- 柔韧性极佳纤维芯（FC）替代钢绳芯，弯曲半径比同规格 IWRC 芯小 15%~20%，适配中等直径卷筒，缠绕收放更顺畅，尤其适合频繁弯曲的吊装工况。
- 耐疲劳性突出WS 复合股结构让股内钢丝受力均匀，反复起升下放时，钢丝间摩擦损耗小，不易出现断丝、股松散问题，使用寿命比普通 6 股纤维芯绳长 20%~30%。
- 抗旋转性较好8 股对称分布的结构可抵消部分旋转力矩，作业时吊物扭转幅度小，避免因旋转导致的载荷偏移，适配长距离提升场景。
- 成本经济纤维芯原材料成本低，同等规格下价格比 8×31WS+IWRC 低 15%~20%，是中重载工况的高性价比选择。
四、应用场景与选型要点
- 适用领域
- 建筑工程：塔吊副钩、施工电梯、卷扬机物料提升；
- 港口装卸：龙门吊辅助钩、卸船机水平牵引；
- 矿山运输：斜井矿车牵引、竖井辅助提升设备；
- 通用起重：中型起重机主副钩、建材与预制构件吊装。
- 选型注意事项
- 安全系数：中重载起重建议 5~6 倍，矿山辅助运输建议 6~7 倍，严禁用于载人设备；
- 环境适配：潮湿 / 户外工况优先选热镀锌型号，定期涂抹钢丝绳专用润滑脂，防止纤维芯受潮腐烂；干燥室内可选光面型号；
- 卷筒匹配：卷筒直径需不小于钢丝绳直径的 18~22 倍，避免过度弯曲导致股结构损伤；
- 替代建议：重载、高挤压、多层缠绕工况，建议选用 8×31WS+IWRC 钢丝绳，提升承载能力与抗挤压性能。

Q
What kind of lubricant can prevent wire rope damage?
A
First, the smooth oil has good fluidity and soaking ability, allowing it to quickly enter the inside of the rope and the rope core when the wire rope is smooth pretreated, and can play a role in preventing bacteria from multiplying inside the rope core fibers.
Second, the lubricating oil adhered to the wire rope will not be easily wiped off, and the smoothing effect will not be affected within the specified temperature range. In addition, the lubricating oil with adhesive function can also prevent skid, which provides assistance for the friction of the elevator wire rope.
Third, it has a high oil film strength, which can resist the extremely high pressure between the steel wires in contact with each other under extremely heavy load, and can also resist decomposition and transformation.
Fourth, smooth oil has high cohesion, which can avoid the dripping of smooth oil, centrifugal loss when there is no exercise, and avoid grease waste and pollution to other equipment.
Fifth, it does not contain ingredients that can cause corrosion and rust in the steel wire rope, and the effect of anti-corrosion and anti-rust is better.
Sixth, its self-correcting ability is strong. When the wire rope is used, it constantly twists and turns, which will cause the surface oil film to continuously knead and expand. This requires a soft and high-temperature oil film to maintain the rope body from cracking.
