Chain Slings for Lifting Tasks
Chain slings consist of one or more lengths of chain with a master link at the top connecting each length. As well as typically having a safety hook at the bottom of each length.
The master link and safety load hook fall under the category of chain components of which there are many different types. So you can change out the component on each leg to something more suitable if necessary. We find the commonly used ones are the hooks with safety catch, ‘C’ hooks, grab hooks, swivel hooks, clevis hooks and self locking hooks. Shortening grabs are also commonly used for shortening the length of the chain temporarily in a safe manner. Find all the dimensions and technical info in the specifications tab above.
The chain itself comes in a wide array of link sizes and this will be dependant upon the lifting capacity you require. For example with a 2 leg chain sling a 10mm chain will handle up to 4.25 tonnes. Whereas a 20mm chain size will enable 17 tonnes to be lifted. The maximum lifting capacity for slings with the same size of chain will increase the more legs are used. For example a 2 leg, 16mm will get you 11.2 tonne but with a 3 or 4 leg of the same size you can achieve 17 tonnes.
The chain length can be almost anything. But we typically supply anything from 1 metre (bearing to bearing) up to 10 metres. Let us know if you require an off standard size.
Using Chain Lifting Slings
Chain slings are relatively straight forward to use, however there are a number of stipulations that must be adhered to. This will depend on which type of chain sling you are using and most importantly how it will be used. Single leg types are relatively straight forward as there is only 1 length of chain and is used in a straight, vertical plain. With multiple leg slings the chain will splay out creating angles from the vertical. It is these angles which will cause the safe working load to change. Therefore you must ALWAYS consult the chain slinging safety charts prior to use to ensure you are not exceeding the stipulated WLL.
Chain slings can also be used in different hitch types other than straight. Basket hitches are the other type of hitch used with a chain sling. In a basket hitch the length of chain passes around the load and hooks back into the master link. Single and double leg slings can be used in this way following the slinging safety charts.
If you find the length of your chain legs are too long for occasional lifting tasks then a shortening clutch can be used. These clutches will temporarily shorten a chain leg in a safe way. You must never attempt to cut, tie or knot chain. Never attempt to shorten it by any other means unless done by a professional.
Other Lifting Slings for Hoisting Applications
Lifting hoists are what we do but as they typically require additional equipment in order to attach loads Lifting Hoists Direct now supply a range of lifting slings to suit. Besides these chain lifting slings we also supply flat webbing slings and round slings. Other associated lifting equipment includes lifting clamps, beam trolleys, and a collection of lifting shackles. Get in touch with your needs for a quick quote.
