Sections

15-8. General Requirements.

Alloy Steel Chain Slings

Only use alloy chain Grade 80 or higher for rigging purposes.
Ensure that attachments in multiple leg slings have a Working Load Limit (WLL) equal to or greater than the chain's WLL.
Label multiple leg slings with the number of legs and their lengths on the tag.

Rigging Hardware

Do not paint rigging hardware unless approved by the manufacturer, as it can hide defects.
Ensure drums, sheaves, and pulleys are smooth and defect-free to avoid damaging rigging.
Use only high-quality connections, fittings, fastenings, and attachments, installed according to the manufacturer's instructions.

Shackles

Use shackles made according to ASME B30.26, with clear markings of manufacturer, WLL, and size.
Ensure shackle repairs or modifications adhere to the manufacturer's specifications, and use parts that meet or exceed original standards.
Follow the manufacturer's instructions for shackle use and load, and adjust rated load when side loading as per the manufacturer or ASME B30.26.

15-8. General Requirements. (d.–f.).

d.  Alloy Steel Chain Slings.

(1)  Use only alloy chain Grade 80 or higher for rigging.

(2)  When used with multiple leg slings, use only attachments (for example, alloy steel chains, hooks, rings, oblong links, pear-shaped links, welded or mechanical coupling links) with a WLL at least equal to that of the assembly chain.

(3)  Multiple leg slings must have the number of legs and lengths identified on the tag.

e.  Rigging Hardware.

(1)  Do not paint rigging hardware unless approved by the manufacturer and according to the manufacture’s requirements.  While the painting of rigging gear for identification is common, USACE considers this an unacceptable practice that constitutes a dangerous condition.  Painting of hardware can potentially cover/hide defects creating an unsafe condition.

(2)  Drums, sheaves, and pulleys must be smooth and free of surface defects that may damage rigging. Drums, sheaves, or pulleys having eccentric bores, cracked hubs, spokes, or flanges must be removed from service.

(3)  Connections, fittings, fastenings, and attachments used with rigging must be of good quality, of proper size and strength, and must be installed according to the manufacturer’s instructions.

(4)  Do not use job hooks, shop hooks and links, makeshift fasteners formed from bolts and rods, or other similar attachments, unless they are according to paragraph 15-8.j.

f.  Shackles.

(1)  All shackles must be manufactured according to ASME B30.26.

(2)  Only shackles marked by manufacturer with name or trademark of manufacturer (country only is not acceptable), WLL, and size will be used.  Shackles must be maintained by the user to be legible throughout the service life of the shackle.

(3)  Each shackle pin must be marked by manufacturer to show name or trademark of manufacturer and grade material type or load rating.

(4)  Shackle repairs and/or modifications may only be as specified by the manufacturer.  Replacement parts and like pins must meet or exceed the original manufacturer’s specifications.

(5)  Use and load shackles according to the manufacturer’s instructions.  Do not apply multiple sling legs to the shackle pin.

(6)  If a shackle is to be side loaded, the rated load must be reduced according to the recommendations of the manufacturer, ASME B30.26, or a QP.
