Lifting slings are available in a wide range of formats; Polyester or chain, endless or flat with an eye each end. These all have a different purpose.
Chains are tough, rugged and heavy, ideal for use when lifting heavy machinery or metal loads with the use of a crane or hoist where surface damage is not an issue as this can be caused by the heavy rough chains crashing down on the load as it is lowered. The metal hooks on the chain can also lead to further damage to the load.
Web slings are flat and made of polyester, usually manufactured to a safety factor of 7:1, as this is the required factor of safety for lifting slings. Regular slings are manufactured to this standard with a double ply of material for extra protection. Double ply or commonly known as ‘Duplex’ are more common these days as insurance companies and other inspecting bodies recommend them. Duplex models are double thickness to ensure total load security up to the rated capacity. This also relies on the equipment being used correctly to the working load limits displayed on the blue tags attached. Web sling products feature a flat eye each end.
Endless Round Slings are lifting slings with no ends. They are measured by circumference and feature working load limits to the customer’s request. Round sling products can be used to choke lift loads where by the sling is used as a choke on the load so when it is lifted the tension is increased and the load is subject to extreme grip and lifting power. Another great feature about round slings is that they are the softest kind of sling and can be used in a wide variety of applications. Just because round slings are soft does not mean they are not as strong as chain slings or web slings, all slings are as strong as their working load limit stated on the blue tags attached to each sling, this is also stated on the certificate of conformity that should be shipped with every sling consignment.
Regular safe working loads from one tonne up to three hundred tonnes there is sure to be a lifting sling suitable for your requirements. All lifting slings can be manufactured to the customer’s specification, this can include lengths, widths and the number of legs on each sling, and if chain slings are required the end fittings can be specified.
