Manufacturing - Our Technical Expertise

We manufacture our products from beginning to end – from the yarn to the final packaged webbing, sling, or lashing strap. Our manufacturing follows several processes and use several different machines for production and testing, of components and finished products. You can find out a little more about our tools below.

The most important steps of producing our lifting slings and lashing straps are:

Weaving – It all starts here, learn a little about the machines we use and the range of webbing we can produce.

Dyeing – This gives us control of the appearance, to provide specified standard colours and bespoke.

Sewing – The key step. If you have ever used a sling that has failed in use (not from us, of course), it is normally the sewing that has given way, not the webbing itself. Find out a little about our sewing machines here.

Round Slings – A special sling also made from polyester, but not woven, see our dual-head Round Sling machine here

Testing – We test to the requirements listed in the applicable EU Standards, both destructive and non-destructive. Meet our large breaking strength test machine here.

Weaving

Weaving the webbing is the foundation of our products. We use top quality yarn and excellent looms to produce webbing of the highest quality.

All products are traceable back to the yarn batches used in their weaving. This means we can provide you with all test results of the raw material used to make your products.

We have a mix of Taiwanese Kyang Hye, and Swiss Jakob Müller AG machines. Both of these manufacturers have world-class reputations, and long histories producing top class looming machines, with Kyang Hye from 1964 and Jakob Müller since 1887. Our choice of looming machines from the top end of the market is deliberate in order to produce top quality webbing.

Our mix of machines lets us produce any width of webbing from 25mm up to 300mm wide. For our North American clients we can also produce webbing of Class 5 and Class 7 breaking strength. We can control the yarn combination used in manufacture, so can provide exactly the webbing grams/meter you need, and indicative black lines and selvedges.

Our loom state webbing is available for bulk purchase, please contact us if you are interested in this product.

If you have any questions or would like a little more information on our machines please let us know.

Dyeing

Our standard yarn is white, and so the loom state webbing is also white (with optional coloured yarn lines). Our dyeing machine helps us perform two operations on the plain woven webbing.

Firstly, and obviously, it adds colour. We can provide the standard colours that indicate Working Load Limit, but we are also able to provide bespoke colouring, and some shade variation if required.

Secondly, the heating and cooling processes experienced by the webbing while being passed through the dyeing machine help to set and tighten the webbing. This reduces the elongation experienced by the webbing under load, and we are therefore also able to pass plain white webbing through without colouring to change the final behaviour.

Both the plain heat-set webbing, and coloured webbings are available to bulk order, please contact us if you have interest in these products.

If you have any questions or require any additional information on our dyeing please let us know.

Sewing

Sewing is a key step in the production of the final lifting slings and lashing straps. Whether it is the join in an Endless sling, creating the eyes of an eye-to-eye lifting sling, or attaching the hardware of a ratchet tie-down, the quality of the sewing is of the utmost importance. This is often the point where a sling will fail, and we therefore control this area very carefully.

Sewing is also very important if producing multi-ply products. Common lifting slings can be simplex (single ply) or duplex (double ply) but we can manufacture products up to 4 ply thick. For these you require experienced sewing staff and good sewing machines.

Finally, the labels and any reinforcement are also attached by sewing. Clearly, a lot of action happens in this department.

We have a mix of manual and automated sewing machines, with the bulk of production using the automated sewing machines. These follow computer controlled sewing patterns designed by our technical manager to provide both quality and consistency. Our sewing staff are also highly trained and experienced, and produce excellent work on our slings.

If you have any questions or require any more information on our sewing, please contact us here.

Round Slings

Round Slings are an alternative type of lifting sling. They are also mainly made from polyester, but this is not woven into webbing and then processed into the required slings.

Instead a single long strand of polyester filament is wound round and round between two points to form a continuous loop, of the required diameter. This is enclosed within a polyester ‘skin’ or cover, to protect the load bearing core. The skin is typically coloured to match the Standard requirement for Working Load Limit.

Our Round Sling machine is dual-head, with which we can produce two slings in parallel. One side can produce Round Slings up to 70 tonnes breaking strength, and the other up to 100 tonnes breaking strength.

We can enclose your Round Slings in single or double covers, and also manufacture adjustable wear sleeves for you – coloured and printed if required. Our European round slings are manufactured according to EN 1492-2.

We are also happy to supply you with yarn, covers or accessories, should you wish to manufacture yourself.

As for our webbing products, all Round Slings and accessories are traceable back to the yarn batches used in their weaving. This means we can provide you with all test results of the raw material used to make your products.

If you have any questions or would like a little more information on our Round Slings or machines please let us know.

Testing

Once you have a finished sling, how do you know it will lift the load it says it will? By testing it.

Our main testing machine is a large hydraulic machine capable of a tensile force of 100 metric tonnes, and testing samples up to 300mm wide. The sample pins are easily interchangeable to different diameters for testing according to EU and US Standards. It is computer controlled and capable of being programmed to carry out the test required, whether this be a breaking test, tension test, holding test or cyclic test. The speed of elongation can also be controlled.

All test reports can be provided for your products.

If you have any additional questions on our testing, or would like any more information, please contact us.
