Designed for overhead lifting, unmatched durability, and excellent performance, alloy chains slings and assemblies are a top choice when it comes to demanding lifting conditions. Although Grade 100 Alloy chain is the most common grade of chain used today, Grade 80 chain is still found in use on on large diameter chain slings 1" and above. Types of alloy chain sling assemblies include single, double, triple, and quadruple leg models. There is also an endless grommet style alloy chain sling available. Additionally, alloy chain slings are available with many different type of hooks like alloy sling hooks, alloy grab hooks, alloy J-Hooks, Alloy Self Locking Hooks, or Plate lifting hooks. Alloy Grab Hooks and Alloy Sling hooks are the most common hook options.
Welded and mechanically coupled alloy chain slings are designed and built for rugged lasting service. As with any quality product, certain precautions and standards of treatment should be observed. Proper care will extend the useful life of the chain sling.
When selecting an alloy chain sling, you will need to choose the type of coupling you prefer. The two types are (W) welded and (M) mechanically coupled.
- Slings shall be shortened or adjusted only by methods approved by the sling manufacturer or a qualified person
- Slings shall not be shortened or lengthened by knotting or twisting
- The sling shall be hitched in a manner providing control of the load
- Slings in contact with edges, corners or protrusions should be protected with a material of sufficient strength, thickness, and construction to prevent damage
- Shock loading should be avoided
- Loads should not be rested on the sling
- Slings should not be pulled from under a load when the load is resting on the sling
- Twisting and kinking shall be avoided
- During lifting, with or without load, personnel shall be alert for possible snagging
- When using multiple basket or choker hitches, the load should be rigged to prevent the sling from slipping or sliding along the load
- When using a basket hitch, the legs of a sling should contain or support the load from the sides, above the center of gravity, so the load remains under control
- Slings should not be dragged on the floor or over an abrasive surface
- In a choker hitch, the choke point should only be on the sling body, never on a fitting
- In a choker hitch, an angle of choke less than 120 degrees should not be used without reducing the rated load (contact BLP)
- Slings should not be constricted, bunched, or pinched by the load, hook, or any fitting
- The load applied to the hook should be centered in the base of the hook to prevent point loading on the hook, unless the hook is designed for point loading
An alloy steel chain sling shall be removed from service if conditions such as the following are present:
- Missing or illegible sling identification
- Cracks or breaks
- Excessive wear, nicks, or gouges. Minimum thickness on chain links shall not be below the values listed in the table on the next page
- Stretched chain links or damage
- Bent, twisted, or deformed chain links or components
- Evidence of heat damage
- Excessive pitting or corrosion
- Lack of ability of chain or components to hinge freely
- Weld splatter
- Hook damage
- Rigging hardware damage
- Other conditions, including visual damage, that cause doubt as to the continued use of the sling.
