Important Facts You Should Know About Lifting Chain Slings
Chain slings are familiar among anyone who works in the lifting industry, and you may have used them for years or even decades. A wide range of choices and a number of guides can help you determine which chain sling to use. High tensile lifting chains 2 leg have many benefits, including being robust, dependable, flexible, and long-lasting with proper care. A small chain sling can lift extremely heavy loads due to its “size to working limit” ratio.
Different configurations for chain slings
One, two, three, and four-leg options are available for chain slings. They are offered in lengths ranging from 0.1 to 50 metres and beyond. Sizes for chains and parts range from 6mm to 32mm. The lifting chains 2 leg can be made up of a variety of parts. It includes bottom fittings, chain connectors, shortening hooks, and the head ring used at the top of the sling. Using the proper chain sling for the lift is crucial, as having a qualified person rig the load when using a chain sling. A chain sling’s operating load limit may be impacted by the angle at which the weight is raised. The operating load limit is lower when using a chain sling at a greater angle.
Inspection before use:
The following should be noted the before using chain slings.
- Before the inspection, clean the sling.
- Check that the lifting chains 2 leg is properly tagged and certified.
- Each individual chain link must be checked for any signs of wear, twisting, stretching, heat damage, chemical attack, or excessive corrosion.
- The degree of wear on damaged links should be measured and should not be more than 10% in any plane.
- Both the upper and lower terminal links, hooks, and other components should be checked for any signs of distortion.
- Connecting links or chain connectors should be checked for wear at the points supporting the weight.
- Wear may be tolerated up to a 10% reduction in thickness of any worn section’s nominal thickness in any plane.
- If any chain links or fittings are defective, they should be clearly marked as rejectable. The sling should be taken out of service until they are correctly fixed.
- Slings with damaged fittings can be fixed by replacing the fittings. But the entire chain assembly needs to be proof-tested before it can be put back into use. The damaged chain must be cut off.
Storing and handling
Chain slings must be stored in a tidy, dry area on a properly constructed rack. Slings should be lightly oiled before being stored if they will be kept for an extended period of time. Never heat-treat chain slings, use them in acid solutions or expose them to other corrosive situations.
Depending on how frequently they are used, lifting chains 2 leg also requires periodic inspection and load testing. The maximum temperature the sling can reach while in use must be considered. The strength of a sling decreases as the temperature in-services increases.
