Easily recognised by the blue painted finish these slings are made from grade 10 alloy steel and come in working load limits up to 10 tonne with link sizes to suit. (see the specification download for all the details).
Grade 10 slings should not be used in hazardous conditions such as off shore of near corrosives. During the lifting set up you should ensure the legs are evenly spaced to ensure stability; asymmetrical lifting is not advised without consulting the manufacturer. The angle where the slings converge into the master link should not exceed 120 degrees.
There is a choice of Cobra grade 10 sling components to finish of the sling to suit your lifting tasks. Slings can be configured in any length up to 10 metres and come with a master link and two connectors; 1 leg is fixed into 1 connector and 2 legs in the other then anchored into the master link.
At the bottom end of the chain – the loading end you can choose from the following components;
Shortening eye type grab hooks can also be permanently added to the master link in order to correctly and safely shorten the chain legs as required.
Full specifications and dimensions can be found in the documentation area above.
At Lifting Gear Direct we have the capability to thoroughly inspect, test, repair and replace all types of chain slings with certification issued to ensure they are safe to use. Besides daily check overs thorough inspections should be undertaken at least every 6 months or more frequent depending on their use. If you notice anything suspect, don't use – get it tested straight away. Repairs can often be made rather than replacing the whole sling.
