Alloy steel chain slings are typically used because of their strength, durability, resistance to abrasion and ability to conform to the shape of a load. These are made of various grades of alloys but 80 to 100 are usually used and are tested by according to ASTM (American Society for Testing and Maintenance) guidelines. Here are tips for safe use of alloy steel chain slings.
- New slings are identified by the manufacturer to show specs like size, grade, rated load and reach.
- Rated load capacities are determined by material strength, design factor, type of hitch and angle of loading.
- Only hooks, rings, oblong and pear shaped links and welded or mechanical coupling links with a rated capacity at minimum equal to the alloy steel chain should be used.
- Personnel should take care to be sure they are clear of areas between the sling and load or between the sling and crane or hoist hook.
- Personnel should not stand in line with or next to legs of a sling under tension, stand under a suspended load or ride the sling unless the load is tested for carrying people.
- Slings should be stored where they will not be subjected to damage, corrosion, moisture or extreme temperatures.
- Slings should be rigged in a way that provides control of the load and should not be shortened by knotting or twisting. Loads need to be balanced and personnel need to be certain there are no snagging hazards.
