Note 1: The values (SWL)in this table are applicable to the tensile strength of the ferrule-secured eye terminals and not to that of the wire rope.
Note 2: Permissible working load values (SWL) are calculated taking a factor of safety as six. Higher factor of safety can be taken according to type of loading. |
