本规范涵盖了用于海军舰载飞机升降机的直径为1.5英寸的镀锌压实股结构钢丝绳（见6.4.8和6.4.9）的要求。钢丝绳必须提供高拉伸刚度，以最大限度地减少与飞机滚上和滚下相关的平台高程变化，并提供在使用中提供一致张力值的均匀密度。它还必须提供良好的弯曲疲劳性能，以适应在升降机系统中的各种滑轮上的重复循环。绳索必须能够抵抗与持续暴露在盐水环境中以及在盐水环境下操作相关的腐蚀。

This specification covers the requirements for 1.5 inch diameter, galvanized, compacted strand construction wire rope (see 6.4.8 and 6.4.9) used for Navy shipboard aircraft elevators. The wire rope must provide high tensile stiffness to minimize the changes in platform elevation associated with roll-on and roll-off of aircraft and a uniform density that provides consistent tension values in service. It must also provide good bending fatigue performance to accommodate repeated cycling over the various sheaves in the elevator system. The rope must be resistant to corrosion associated with continual exposure to and operation in a salt water environment.
