- 轻载抗挤压，适配轻型多层缠绕6 股结构 + K 型压实工艺，结合 EPIWRC 芯的高支撑刚度，能承受自动化吊具、小型起重机的多层缠绕挤压应力，股间变形量比普通 IWRC 型号减少 22%~27%，适配高频次轻载起升下放作业，尤其适合自动化生产线的连续吊装场景。
- 低旋转高稳定，保障轻载精准吊装6 股对称排列 + 交叉捻向设计，配合聚合物填充层的应力缓冲作用，轻载吊装时吊钩旋转幅度控制在极小范围，避免精密仪器、易碎货物摆动引发的磕碰损坏，满足高精度吊装的作业需求。
- 防腐缓冲双优，延长使用寿命热镀锌镀层 + 聚合物填充层形成双重防腐屏障，隔绝潮气与腐蚀介质，适配沿海、潮湿仓库等轻度腐蚀环境；填充层同时缓冲启停冲击载荷，减少钢丝间的微动摩擦，耐疲劳性能是普通 6×19S+FC 钢丝绳的 1.8~2.2 倍。
- 低维护成本，提升作业效率聚合物填充层自带减摩效果，无需频繁加注润滑脂，相比普通钢芯钢丝绳的维护频次降低 50% 以上，减少自动化设备的停机时间，提升轻型吊装作业的整体效率。
四、选型与使用要点
- 安全系数选择
- 自动化轻型吊具 / 精密仪器吊装：6~8 倍
- 小型起重机主钩 / 建筑小型塔吊起升：7~9 倍
- 严禁用于重载吊装、强酸碱腐蚀无防护、超高温（＞150℃）等极端工况
- 环境适配原则
- 干燥室内自动化生产线 → 电镀锌全绳型号
- 户外 / 沿海轻腐蚀环境 → 热镀锌型号，定期抽检填充层完整性
- 强腐蚀环境 → 搭配聚氨酯（PU）护套，隔绝腐蚀介质
- 卷筒与滑轮匹配
- 卷筒直径 ≥ 钢丝绳直径的 25~30 倍
- 滑轮直径 ≥ 钢丝绳直径的 22~27 倍
- 滑轮槽底需为圆弧深槽精密加工，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 钢绳芯钢丝绳专用防腐润滑脂，采用高压注脂设备，确保润滑脂渗透至股间缝隙；严禁拆解绳芯，避免破坏聚合物填充层
- 检查重点为 股端断丝、绳径磨损、镀层脱落、填充层鼓包或开裂，出现单股 2 丝断丝或填充层大面积破损时需立即报废
- 运输与存放时需使用专用轻型支架盘卷，避免挤压变形、尖锐物划伤镀层；长期存放置于干燥通风环境，定期检查防锈情况

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.
