型号部分 含义说明 8 外层为 8 个工作股，对称排列设计配合交叉捻向结构，可有效抵消承载时的扭转扭矩，实现低旋转特性，避免中载吊装时吊钩打转、货物摆动 ×K26WS K 型压实瓦林吞 - 西鲁式股（WS=Warrington-Seale 复合结构），每股由 26 根粗细交替钢丝排布而成，经冷压实工艺处理后股径缩小、钢丝贴合紧密，金属截面积利用率大幅提升，抗疲劳、抗磨损性能远超普通捻制股 -FC 绳芯为 纤维芯（Fiber Core），材质多为聚丙烯或剑麻，相比独立钢绳芯（IWRC/PWRC）重量更轻、柔韧性更好，适配中小型卷筒的频繁弯曲作业，降低设备负载损耗 一、基础结构参数
参数项 详细说明 结构组成 8 个 K 型压实瓦西式外层股 + 纤维芯（FC，聚丙烯 / 剑麻材质）；外层股与绳芯采用交叉捻向（外层右捻、芯左捻），绳体圆整度高，旋转扭矩低，柔韧性优于同规格 8×K26WS-IWRC 型号 钢丝材质 优质高碳钢（#82B、#925），经冷拔强化 + 股压实处理；外层股钢丝表面可选热镀锌 / 电镀锌 / 光面，按需匹配防腐与耐磨需求 表面处理 1. 热镀锌：镀层厚 30~60μm，适用于沿海高盐雾、矿山潮湿等中腐蚀中载场景2. 电镀锌：镀层厚 8~15μm，适用于干燥室内中重型起重工况3. 光面：无镀层，需定期加注专用润滑脂，适用于无尘高精度吊装场景 直径范围 常见 12~52mm，主流应用 18~44mm 中重型提升 / 牵引场景 公称抗拉强度 高碳钢型：1770MPa、1960MPa、2160MPa（中型吊装设备优先选用 1960MPa 等级，兼顾强度与柔韧度） 重量系数 0.380~0.410（比同规格 8×K26WS-IWRC 轻 22%~26%，轻量化优势显著） 最小破断拉力系数 0.300~0.320（K 型压实工艺提升金属利用率，比普通 8×26WS+FC 系列提升 13%~18%，满足中载作业强度需求） 二、典型力学性能表（1960MPa 热镀锌 + 聚丙烯纤维芯）
公称直径（mm） 参考重量（kg/100m） 最小破断拉力（kN） 适用场景 18 85 380 小型施工升降机承重绳、物料提升机主绳 26 180 880 小型履带吊副钩绳、港口轻型装卸设备牵引绳 34 310 1550 建筑塔吊变幅绳、风电塔筒配件吊装绳 42 480 2400 中型港口卸船机辅助绳、重型预制件短途转运绳 注：若选用剑麻纤维芯，耐温性（≤120℃）优于聚丙烯芯，但耐水性较差，重量略增 3%~5%；热镀锌处理对破断拉力的影响小于 2%。三、核心特性
- 中载高柔韧性，适配频繁小半径弯曲K 型压实股保障中载承载能力，纤维芯的弹性缓冲作用让绳体弯曲半径比同规格钢芯型号小 23%~28%，能适配中小型卷筒的高频次起升下放、换向作业，尤其适合塔吊变幅、轻型装卸设备等需要频繁调整吊装角度的场景。
- 轻量化设计，降低设备负载损耗纤维芯替代钢绳芯，整体重量大幅降低，人工搬运、安装更省力，同时减少起重设备的整机负载，延长设备传动系统与卷筒的使用寿命，适配需要频繁移动的中型吊装设备。
- 耐磨耐疲劳，使用寿命长瓦林吞 - 西鲁式股的外层粗钢丝与滑轮、卷筒接触面积均匀，磨损速率低；压实工艺让股内 26 根钢丝紧密贴合，减少微动摩擦损耗，耐疲劳性能是普通 8×26WS+FC 钢丝绳的 1.7~2.1 倍，降低设备运维成本。
- 防腐性能可控，维护成本低热镀锌镀层附着力强，可抵御沿海盐雾、矿山潮湿等腐蚀环境；搭配纤维芯专用防腐润滑脂，既能润滑钢丝接触面，又能防止纤维芯受潮腐烂，维护周期可延长至普通纤维芯钢丝绳的 1.5 倍。
四、选型与使用要点
- 安全系数选择
- 小型履带吊副钩 / 建筑塔吊变幅机构：7~9 倍
- 港口轻型装卸 / 风电配件吊装：9~11 倍
- 严禁用于矿山竖井提升、超重型设备长期悬挂、高温（＞120℃）等重载高危工况
- 纤维芯选型建议
- 户外潮湿 / 沿海腐蚀环境 → 聚丙烯纤维芯（耐水耐腐蚀，性价比高）
- 钢厂附近等高温作业场景 → 剑麻纤维芯（耐温性好，需做好防水防护）
- 高精度无尘吊装场景 → 改性聚丙烯纤维芯（低粉尘脱落，清洁度高）
- 卷筒与滑轮匹配
- 卷筒直径 ≥ 钢丝绳直径的 18~23 倍
- 滑轮直径 ≥ 钢丝绳直径的 16~20 倍
- 滑轮槽底需为圆弧浅槽精密加工，与绳径精准匹配，避免股丝受力不均引发断丝
- 维护注意事项
- 定期加注 纤维芯钢丝绳专用防腐润滑脂，采用低压注脂方式，确保润滑脂渗透至股间缝隙，不可使用钢绳芯专用润滑脂（易堵塞纤维芯孔隙）
- 检查重点为 股端断丝、绳径磨损、纤维芯外露、镀层脱落，出现单股 2 丝断丝或纤维芯外露时需立即报废
- 运输与存放时需防潮防晒，盘卷整齐避免挤压变形；长期存放需置于干燥通风环境，每 3 个月翻动一次，防止局部锈蚀

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.
