RUD - Round Steel Link Chains and Conveyor Systems

With over 130 years' experience we are developing future-oriented solutions with chain systems and components for different applications on the basis of the round steel link chain. All our products are a result of our passion to creativity and perfection in our core competences metal working, welding, heat treatment and surface technology.

The longstanding partnership with our customers, their satisfaction and confidence in us are the foundations for our success. Our ongoing commitment to customer oriented, technical innovations, research and development throughout the organisation as well as for highest quality and safety is our common responsibility.

Through our actively practiced, open and trusting corporate culture as well as our ongoing training and education, our international family enterprise is a motivated, energetic, flexible and competent team.

CHAIN COMPONENTS FOR ASH HANDLING SYSTEMS

As well as supplying round link chain and components for heavy-duty elevators and conveyors, our long relationship with the coal-fired power generating companies includes the supply of chain components for ash handling systems. Continuous removal of this highly abrasive, corrosive and, sometimes, super-hot material requires the most robust and reliable systems.

Until now, scarper bars have been attached to the drive chains by various means ranging from passing rudimentary bolts in between the links to complicated in-line flat-link assemblies that require an entire team for routine maintenance breaks. Invariably these methods require the attachment of complicated and inelegant fixing points to the ends of the scraper bars.

Bad geometry and poorly tensioned drive chains lead to uneven wear, irregular travel and scraper 'jumper' which reduces system efficiency and, most significantly, the TPH removal rate.

As part of our on-going product development programme, a careful study of ash-handling systems, detailed client consultation and extensive field trials have given birth to the Duomount.

DUOMOUNT

The Duomount attachment consists of two identical, reversible, drop-forged chain components. The claw-shaped ends pass through the 'eyes' of two adjacent chain links to firmly embrace the joining link. To avoid fouling the claws do not protrude beyond the diameter of the chain.

As completion of the operation the two parts of the Duomount are bolted together forming a simple flange at the end of the scraper bar (for best results, the flanges should be integrated at the point of manufacture.) Apart from the unique design and high quality performance of the Duomount attachment one of its main advantages has to be seen in the fact that the chain remains intact and fully tensioned during the entire assembly works. The whole process is a matter of few minutes only and can even be executed by non-skilled staff.

HIGH-PERFORMANCE MATERIAL HANDLING SYSTEM

RUD Apron Conveyors are designed for multiple purpose and have been installed in dry deashing systems of fossil fired power plants.

Along with the advantages of the round steel link chain as the pulling element, the RUD apron conveyor has the following advantages:

• Completely closed slat floor over the total lifespan
• No opening of the slats when moving around the drive wheels
• Short pitch reduces polygon effect
• Lower construction height due to smaller diameter wheels
• Robust simple construction with high slat rigidity
• Round link chain system is self cleaning and can work in wet, abrasive, corrosive and dirty environments without seizure of links.

RUD CONVEYOR SYSTEMS

RUD conveying systems provide best possible solutions for unit loads, for bulk material and the mining industry based on round steel chain as a conveying mechanism. Design and supply chain based, for bulk material handling, individually engineered for each specific requirement.
