Gunnebo Johnson Corp. provides a blank identification tag, attached by a coupler, to be stamped with sling WLL, minimum working range angle, serial number, chain size, grade, reach, type and manufacturer. Order 547303 for replacement.
Grade of component with the lowest breaking strength shall be specified on the identification tag. Nonstandard grades shall be designated by “NS.”
Working Load Limit (WLL) is the maximum working load for a specified working range. Sling working range includes sling leg angles from 90° to a specified minimum. The specified minimum working range angle is given on the identification tag.
Working load is to be applied vertically to a sling assembly having symmetric leg angles. WLL applies to loads lifted vertically and does not include torsional, binding, shock or non-symmetrical load effects.
Gunnebo Lifting Grade 100 Alloy Steel Chain Straight Leg and Basket Sling Working Load Limits for selected working ranges of symmetric sling leg angles are listed in pounds and given in TABLE 1A & 1B. No chain sling shall be rigged with a leg angle less than 30° from the horizontal.
