CHAIN SLING WORKING LOAD LIMITS (WLL)
Do you know which grade of chain you require as well as the chain sling working load limits (WLL) for your lifting application. Is you load too heavy for the chain sling you are using ? Read more below………
SELECTING CORRECT SLINGS
Determining the correct chain slings is critical when lifting loads to reduce the risk of accidents in the workplace and to help keep workers and the public safe.
FACTORS TO CONSIDER FOR THE CORRECT LIFTING SLING
- work out the weight of the load to be lifted.
- are grade 80 chain slings, grade 100 chain slings or grade 120 chain slings required
- Determine if the correct lifting method for the load requires a single leg, multiple leg or an endless sling configuration.
- Consult the WLL table to determine which size chain will safely lift the load, and within what range of sling angles, using the selected sling configuration.
Note: The sling angle is equal to twice the greatest angle of inclination of a leg to the vertical. - Determine the required effective length of the sling to be within that range of sling angles.
Note: The effective length of a sling is the distance between the two working surfaces. - Order your selected sling fully assembled and ready to use.
Safety Check: Before lifting, inspect the chain and fittings identification markings to ensure the sling is correctly tagged
for its application. Refer to AS 3775.2 for further guidance.
