Welded Steel Drag Chain

An extra wide conveyor chain offering a large contact area therefore reduced pin and bush loadings which in turn provides a reduced wear rate. Often found on in feeds for other systems which are used in the timber and paper processing industries.
The common W1 welded scraper attachment is available as standard along with the C1 full length carrier/plate attachment. Other attachments are also available upon request.
WD – Welded steel chain with through hardened pins and case-hardened bushes.
WDH – Welded steel chain – all components fully head treated.

Welded Steel Drag Chain

These extra wide chains are often used in heavy duty feeding application such as log feeds in lumber mills. They may also be found in numerous other industries with the most common being grain handling conveyors and the sugar processing lines. The welded formed barrel and long pin offer a large bearing area which helps to prevent wear, with the greater width also offering a large carrying area. Various attachments are available for these chains, with the most common being a folded scraper attachment welded on both sides.

We work hard so that your conveyor chain can too - Premium Manufacturing as Standard
All our conveyor chains are manufactured using the very latest manufacturing technology and techniques. With fully punched and shot peened link plates, CNC machined components, precision component fits, in house heat treatment, fully ground round parts and heavy-duty spin riveting, our standard is designed and proven to outperform other leading brands.

Cropped links from medium carbon steel
Our link plates are precision punched from cold drawn steel. Not only does this limit internal stress, but it also provides a precision hole pitch and increased tensile strength due to grain alignment.

Shouldered or flatted case-hardened bushes
Inserted with a press fit to prevent rotation and produced from on-size chromium-molybdenum seamless tube for minimum distortion, superior concentricity and maximum strength.

Shouldered or flatted case-hardened pins
Secured with a press fit and spin riveting. Selective in-house induction hardening allows deep case depth on wearing surfaces without stressing/cracking the pin ends during assembly and riveting.

Hardened and ground Precision Rollers
Through hardening and a light grind after heat treatment ensures a dimensionally accurate roller with a good hardness even after wearing during operation.

ISO 9001 and full traceability
Strictly manufactured to ISO 9001 with quality checks at every stage of manufacture. Our chains are fully traceable back to their original materials, which are also independently tested upon delivery.

Our Standard range and above features cover; British Standard (Z) Series, M Series and FV Series

Whatever your requirements, we have all the options covered
There are a wide array of nonstandard and heavy-duty conveyor chains used throughout industry today. These chains are often developed to offer extended service lives, increased strength, enhanced reliability and operational speed or perform special duties within the industries that they serve. Challenge has well recognised experience in many of these industries, including;
• Palm Oil
• Sugar
• Cement
• Automotive
• Timber and Paper
• Steel manufacturing
• Food
• Mining
• Waste and Recycling
• Bulk Material Handling
• Ovens
• Water Treatment
• Agriculture

We can cater for a wide range of special requirements, which includes but is not limited to;
• Plasma nitride hardened pins and bushes
• Stainless steel (all grades)
• Sherardized plates and attachments
• Molykote dry lubricants
• Hot dip glavanizing
• Zinc/nickel plating
• Food grade oils
• Nonstandard chain pitches

Sprockets to suit our entire conveyor chain range
Transmission and Conveyor chains are driven by sprockets. The even distribution of power relies on accurate gearing between the sprocket teeth and the chain rollers or bush.
As sprockets greatly affect the life of the chain, all Challenge sprockets from cast through to precision machine cut are manufactured to strict tolerances and quality controls. We also advise all of our customers to replace their sprockets whenever a chain is replaced in order to maximise the chains life.

All lengths/coils of conveyor chain are supplied with a standard connecting link on the end of each length or coil.
