- 柔韧性与抗挤压均衡WS 复合股结构降低了股内钢丝的接触应力，搭配 IWRC 钢绳芯，既能适配中等直径卷筒（弯曲半径小），又具备良好的径向抗挤压能力，多层缠绕时绳体不易变形。
- 耐疲劳性优异线接触设计让钢丝受力均匀，反复起升、下放过程中，钢丝间摩擦损耗小，不易出现断丝、股松散问题，使用寿命比普通点接触钢丝绳长 25%~35%。
- 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，适配长距离提升或下放工况。
- 性价比突出相比大丝数的 8×31WS、8×36WS 钢丝绳，该型号生产工艺更简洁，成本更低，同时能满足多数中重载设备的使用需求。
四、选型与使用要点
- 安全系数选择
- 中型起重 / 建筑吊装：5~6 倍
- 矿山运输 / 港口装卸：6~7 倍
- 严禁用于载人设备及高危重载工况
- 环境适配原则
- 干燥室内 → 光面碳钢绳
- 普通户外 → 热镀锌碳钢绳
- 沿海 / 酸碱腐蚀环境 → 合金钢丝热镀锌型号
- 卷筒与滑轮匹配
- 卷筒直径 ≥ 钢丝绳直径的 18~22 倍
- 滑轮直径 ≥ 钢丝绳直径的 16~20 倍
- 避免小直径卷筒过度弯曲，防止股结构松散
- 维护注意事项
- 定期加注钢丝绳专用润滑脂，减少钢丝磨损与锈蚀
- 检查时重点关注股间是否有断丝、变形，出现 3 丝以上断丝需及时报废

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.
