普通起重用途的4级锻钢吊环螺栓

[中文适用范围]： 本国际标准规定了一般起重用途的 4 级锻钢吊环螺栓的一般特性、性能和与其他部件的互换性和兼容性所需的关键尺寸。 这些吊环螺栓可用于轴向和倾斜载荷。 本国际标准规定了吊环螺栓的孔眼尺寸，允许与 ISO 2415 中定义的相同工作载荷限制的卸扣直接连接。 这些尺寸还允许设计更大的孔眼，从而允许与类似工作载荷的吊钩直接连接限制。 本国际标准涵盖与第 4 条中定义的 4 级吊环螺栓相关的所有重大危险、危险情况和事件。 本国际标准适用于在 20 °C 至 200 °C 温度范围内使用的 4 级吊环螺栓。 本国际标准不适用于非整体锻造的吊环螺栓。 本国际标准不适用于在其作为国际标准发布之前制造的 4 级锻钢吊环螺栓。 [外文原描述]： ISO 3266:2010 specifies the general characteristics, performance and critical dimensions necessary for interchangeability and compatibility with other components, of forged steel eyebolts grade 4 for general lifting purposes. These eyebolts can be used for axial and inclined loading. ISO 3266:2010 specifies the dimensions of the eyes of eyebolts permitting direct connection with shackles of the same working load limit as those defined in ISO 2415. These dimensions also allow designs with a larger eye which can permit direct connection with sling hooks of similar working load limit. ISO 3266:2010 covers all significant hazards, hazardous situations and events relevant to eyebolts grade 4. ISO 3266:2010 is applicable to eyebolts grade 4 for use in the temperature range of -20 ºC to 200 ºC. ISO 3266:2010 is not applicable to eyebolts which are not forged in one piece. ISO 3266:2010 is not applicable to forged steel eyebolts grade 4 manufactured before the date of its publication as an International Standard.
