 In the following section we have covered the main lifting requirements for flat webbing, roundslings, chain, wire and rope. However, owing to the wide range of uses that these are put to, it has not been possible to include our full range of supplies and services. We pride ourselves on being adaptable and can supply anything our customers require so, if there is a particular combination or design that you require please contact our sales and technical staff. Flat Webbing Lifting Systems
Flat Webbing Lifting Slings are made from high tenacity polyester webbing, colour coded for ease of identification for lifting and are manufactured to BS EN 1492-1:2000. They are available in three basic types: Simplex, Duplex and Endless. Simplex Slings are manufactured from single thickness webbing, whereas Duplex slings are manufactured from double thickness webbing. Both are either terminated in a metal end fitting or, more popularly, sewn back upon themselves with a high tenacity nylon fabric to form a reinforced Becket Eye, which provides greater durability than the traditional leather eye. The webbing is stitched close to the eyes which are 9" long bearing to bearing. Endless slings, however, are manufactured from single thickness webbing sewn in a continuous loop with an overlap. These slings are mainly used when needing a wide grip on large equipment, e.g. for lifting pipes. In order to protect the webbing from unnecessary wear and tear, various sleeving is available, in any length, which can also protect both the sling and any fragile loads. Advantages of webbing and round slings
 Round Slings
In addition to flat webbing slings we also supply various round slings, which are particularly useful for lifting loads of a fragile nature and which may be damaged by the harder webbing. Round Slings are manufactured to BS EN 1492-2:2000 from 100% polyester. The outer cover is a seamless polyester sleeve of double thickness construction and has an excellent abrasion resistance. The core consists of a continuous hank of high tenacity polyester yarn (see illustration) which is immensely strong and durable. Due to the parallel fibres in the core (see illustration), the stretch experienced with a roundsling is less than 3% at the safe working load, which eliminates dangerous dancing experienced with some slings. Cover pads, made from reinforced nylon fabric, are available to protect the roundsling when lifting sharp edged loads. These are sewn around the roundsling making them movable if necessary. Round slings, as with flat webbing slings, are colour coded for ease of identification and are available in a complete range of sizes and strengths. Always ensure that the webbing or roundsling is appropriate for the job and if in doubt ask - our technical support team are always available to help.  click here for table of specifications How to order

Code of Good Practice for Flat Webbing Slings and Round Slings
Rope Lifting Slings
As with all forms of lifting slings, care must be taken to ensure that your rope sling does not become damaged and terefore weakened by misuse. In particular care must be taken to prevent the sling from being damaged by the object being lifted. Common causes of such damage can be avoided by:-
For full details of all our rope products please see our main rope section. If you are in any doubt about the sling, please contact out technical department who will be happy to advise on our lifting slings.  click here for table of specifications Steel Wire Rope Slings
Wire Rope Slings are available in a wide range of sizes, configurations and capacities as illustrated. The slings are manufactured to BS1290, and BS302; BS365 for Galvanised slings. Slings are supplied with either soft or thimble eyes secured by ferrules. The safe working load of the sling is clearly stamped on the ferrule. We can also supply a wide range of end fittings to suit particular applications, including hooks, shackles etc. Special slings will be constructed on request. As with all lifting slings, wire slings must be regularly and thoroughly inspected. Regular lubrication can considerably increase the life of a wire rope sling. The lubricant should be suitable for the purpose; if in doubt please check with our technical staff before using a lubricant. Do not use solvents to clean a wire rope before applying lubrication. Paraffin is not recommended, but if absolutely necessary can be used with a cloth to prevent excess paraffin penetrating the wire rope. If broken wires are found in a wire rope these should not be cut off - grip the broken ends with pliers and bend backwards and forwards until the wire breaks in the gusset between the strands.  click here for table of specifications Chain Lifting Slings
Although webbing and round slings are hugely popular for most lifting purposes, chain is still used primarily for many specific types of lifts. Chain is of primary use when lifting loads which may cause damage to the webbing, even with protective sleeves. Chain is still mostly used for lifting strip steel, scrap metal and any drums containing certain chemicals, i.e. alkalines. As with webbing and roundslings, care must be taken when using chain for lifting. If lifting loads that have sharp corners, protect the chain as much as possible as the links may become damaged and alter shape. This can cause severe weakening to the chain and must be repaired immediately.  Chain Working Load Limits
When deciding the size of chain sling required, consideration must be given to the mass of the load and the angle between the legs. As the angle increases the working load limit decreases, as shown below - the most popular angle is 90°. (SWL in tonnes - Safety factor 4:1. Limits refer to normal use and equally loaded sling legs).  click here for table of specifications The Working Load Limit (W.L.L.) is the maximum load which should be applied to a chain sling when used in normal working conditions and is based on a safety factor of 4:1. As working conditions can vary widely the Safe Working Load (S.W.L.) should be determined by a competent person with full working knowledge of the service conditions of the chain sling. When chain slings are to be used in temperatures above 200°C or in acidic conditions, or if you are uncertain about anything, advice should be sought from our technical staff. Asymmetric loading conditions
For unequally loaded chain slings we recommend that the Working Load Limits be determined as follows:-
Specification
All our chain slings use Grade 80 chain that conforms to BS EN 818-4 and all components are fully compatible with chain dimension and strength. The chain and components are manufactured from quenched and tempered alloy steel and have a very high strength factor, with a high wear resistance and guarantee for a long life. We operate a high quality control programme and rigorous testing of every component ensures complete safety, whilst every sling is individually marked with its safe working load and an unique numbering system for complete traceability.
