Single-leg grade 100 lifting chains with grab hook on one end and latch/slip hook on other end are a durable option for lifting. Each assembly has domestic chain and end fittings, along with a certified lifting tag. Working load limits range from 3,500 lbs to 35,300 lbs.

CHAIN SLING SELECTION & WORKING LOAD LIMITS

HOW TO SELECT THE PROPER CHAIN SLING

1. Determine the weight and configuration of the load(s) to be lifted.
2. Determine the type of the chain sling required, according to weight and configuration.
3. Determine the size of the body chain according to the working load limits.
Be sure to take into consideration the effect of the required angle (see diagram below)
4. Determine the reach required to give the desired angle. This is measured from the upper bearing surface of the master link to the bearing surface of the lower attachment.
Know share of load on pick points and location of center of gravity.

WHAT DETERMINES A SLING'S WORKING LOAD LIMIT

The working load limit of slings is based on the following factors:

  • Type of hitch
  • Material strength
  • Design factor
  • Diameter of curvature (D/d)
  • Angle of loading

For specific information on the working load limit of various slings, see page 31.
When using a sling, loads are frequently lifted at an angle. This can affect their working load limits.
In the diagram to the right, the percentages shown represents the maximum working load limit of the sling when used at the designated angle.

For example:
One 3/8" Grade 80 double sling used at 90deg would have a working load limit of 2 times the working load of a 3/8" Grade 80 single or 2 x 7, 100 lbs. = 14,200 lbs.
The same double sling used at 35deg would have a maximum working load limit of 57% of 14,200 lbs. or .57 x 14,200 lbs = 8,094 lbs.

Warning!
Improper use, application or care of slings can result in injury or property damage.
To avoid injury or damage:

  • Never exceed the working load limit. Confirm the working load limit of all sling components are of equal or greater strength.
  • Always inspect slings before use for wear, damage, and elongation, Refer to ANSI B30.9 and OSHA regulations.
  • Do not impact or shock load. Apply load slowly.
  • Protect from corrosion and high temperatures.
  • Use with alloy chain for overhead lifting.
  • Do not use twisted, knotted or kinked chain.

American National Standard ANSI B330.9, the National Association of Chain Manufacturers, and the Occupational Safety & Health Administration recommended only the use of alloy steel chain for overhead lifting i.e. for sling chain. Slings may be constructed by the user using CM Grades 80 or 100 Chain, CM alloy attachments and CM mechanical coupling links (Hammerloks). Columbos McKinnon uses Grade 80 or 100 chain and alloy steel welded coupling links instead of Hammerloks for construction of welded slings. Refer to this catalog's product overview sections for "Chain," "Hooks" and "Rings and Links" for detailed information on components which may be used in the construction of slings.
