RUD Gambarotta heavy duty apron feeders provide controlled, reliable extraction of heavy and abrasive bulk materials in demanding environments. Built for Australian mining, quarrying, cement and steel industries, they offer high durability, reduced maintenance and strong performance in harsh, remote and high-throughput conditions.

RUD Gambarotta EP and EPP series heavy duty apron feeders are designed for reliable extraction and controlled feeding of large, heavy and abrasive bulk materials. With reinforced steel pans, heavy duty chains, impact rails and high strength drive components, they deliver consistent throughput while protecting downstream equipment. These feeders are widely used across the Australian mining, cement, quarrying and steel industries, where durability, load control and low maintenance are essential.

The Role of Apron Feeders in Material Handling

The first stage of material handling, extracting material from a hopper, stockpile or unloading system, is one of the most challenging. Equipment must manage high impact loads, large lump sizes and abrasive materials without failure. Apron feeders are designed for this task. Unlike conventional conveyors, they provide a slow, controlled and positive feed, making them suitable for heavy duty, continuous operations. In Australia, where sites often operate remotely and around the clock, reliability at this stage is critical to maintaining plant uptime and avoiding costly disruptions.

How Apron Feeders Work

EP and EPP feeders use overlapping steel pans mounted on dual parallel chains to form a continuous moving deck. This deck travels slowly beneath the hopper, extracting and conveying material at a controlled rate. This movement prevents surging and ensures that downstream equipment (crushers and screens) receives a steady feed. Impact rails beneath the loading zone absorb the energy of falling material. The pans flex elastically under load, transferring most of the impact force into the frame before returning to their supported position on rollers, reducing stress on moving components. Support rollers with double ball bearings eliminate sliding contact, improving efficiency and reducing wear, which is important for sites with limited maintenance access.

Choosing the Right Feeder: EP vs EPP?

EP Series - Proven Performance

The EP series is designed for reliable performance in standard heavy duty applications.

EPP Series - Reinforced for Extreme Conditions

The EPP series includes additional reinforcement for more demanding environments.

EPP feeders are suited for extreme loads, high drop heights and highly abrasive materials, common in Australian mining and quarrying.

RUD TECDOS chain drive technology enables the precise and reliable movement of 35-tonne movable roof sections in a demanding bulk handling environment. Designed for durability in dusty conditions, the system ensures smooth operation and improved efficiency at a European port facility.

Bulk material handling requires more than just storage space. Operators must ensure easy access for loading and unloading while protecting stored materials from weather. A project at the Enns port precinct in Europe demonstrates how engineered chain drive technology can help. By incorporating an automated sliding roof system powered by RUD TECDOS chain drive technology, the handling hall at Danubia Speicherei provides operational flexibility while maintaining durability in demanding industrial conditions.

A Storage Facility Designed for Efficient Material Handling

The handling hall, operational for over a year, was designed for loose bulk goods such as animal feed. Strategically located with road, rail, and waterway access, the facility serves as a key logistics hub. It includes three reinforced concrete storage bays, each approximately 33 metres long, 10 metres wide and over 12 metres high.

Above each bay is a movable roof section measuring 33 x 10 metres. Unlike conventional roofs, these open and close automatically, allowing loading from above using cranes. Each roof weighs about 35 tonnes and can be controlled independently via a wireless remote, enabling separate access to all bays and improving operational flexibility.

Engineering the Movable Roof Concept

From the planning stage, Danubia Speicherei saw the advantages of a movable roof. The roof’s size and weight made design more complex than conventional buildings. They partnered with an engineering specialist experienced in lifting and mechanical handling technology, responsible for the drive system, control technology and mechanical integration. The company worked closely with RUD Germany to deliver a reliable drive solution for heavy loads.

TECDOS Chain Drive Technology for Heavy Loads

The roof system is powered by the RUD TECDOS Pi-Gamma Drive System, a compact chain drive solution for demanding industrial applications. Each roof section uses four drive units working together for smooth operation.

The Pi-Gamma system combines a fixed 180-degree chain deflection (Pi configuration) and a variable deflection between 90 and 180 degrees (Gamma configuration), allowing efficient operation in horizontal and vertical applications. The system uses a high strength round steel chain on a specially designed drive shaft, minimising mechanical forces while ensuring reliable power transmission. The TECDOS chain drive system is suitable for heavy industrial applications, including bulk handling infrastructure and large mechanical installations.

Each storage bay uses a 33m long round steel chain (TEC12), supported by rollers at two metre intervals to ensure smooth movement and reduce sagging.

Built for Harsh Bulk Handling Environments

Bulk storage environments pose challenges for mechanical equipment due to high dust levels. Chain drive technology was selected for its reliability in such conditions. Heavy duty chains resist dust contamination and require minimal maintenance. The system is also durable and corrosion resistant, suitable for outdoor exposure.

The Pi-Gamma system is compact, with TEC12 drive units having a pitch circle diameter of 82.3 millimetres and weighing around 12 kilograms, yet capable of moving extremely heavy loads.

Managing Wind and Weather Conditions

At over 12 metres tall, the roof structures are subject to wind forces. Engineers designed the system to withstand pressures up to 120 N/m². Roof sections can be mechanically locked during adverse weather. Narrow roof gaps prevent water entry, protecting stored materials. Snowfall can add up to 15 tonnes per roof, but the drive system can move loads of approximately 50 tonnes horizontally, ensuring reliable year round operation.

Designed with Future Expansion in Mind

Danubia Speicherei operates multiple facilities in the Enns port precinct. The new hall allows expansion by duplicating the layout, effectively doubling storage capacity while maintaining performance and efficiency using the same movable roof concept and chain drive technology.

Engineered Drive Solutions for Industrial Infrastructure

The Enns port installation highlights how modern drive technology supports large scale industrial infrastructure. By combining robust mechanical design with compact high performance chain drives, TECDOS Pi-Gamma systems provide reliable motion control for heavy structural components. For bulk handling facilities, ports and logistics operations, RUD’s engineered solutions deliver durability, flexibility and efficiency.

RUD TECDOS drive technology provides precise and reliable control of sluice gates in dams, reservoirs and industrial applications. By ensuring safe, consistent operation in critical water management systems, it supports compliance, protects infrastructure and improves long-term performance.

The Risk in Traditional Sluice Gate Drives

Many old sluice gates still use non-calibrated lifting chains and non-standard pocket wheels that were never designed to operate efficiently as a single unit. In such gates, lifting chains and pocket wheels are sourced from different manufacturers. These components may appear compatible, but they are not calibrated to operate together. As the non-calibrated chain articulates over a non-matching pocket wheel, misalignment can occur, resulting in pinging, jolting, and uneven load transfer.

Over time, this can accelerate wear and tear, increase vibration and place stress on the drive system. In the worst-case scenario, the chain can fail to sit correctly on the pocket wheel, preventing the gate from opening or closing when required. During high water flow or floods, this type of failure can have serious consequences, including flooding, plant shutdowns, or unplanned downtime for repairs. The issue is simple: non-calibrated lifting chains are not suited to precision sluice gate applications, particularly when paired with pocket wheels manufactured to different tolerances and standards.

RUD Precision Engineering

RUD is a world leader in drive technology. We provide solutions through a fully integrated approach to chain and drive technology. RUD lifting chains are 100% calibrated using state-of-the-art manufacturing and measurement technology. The matching pocket wheels are designed and produced to the same exact tolerances, ensuring smooth articulation, correct load distribution and reliable operation.

Both the chain and the pocket wheel are manufactured in Germany, in the same facility, drawing on more than 150 years of chain engineering expertise. This single-source manufacturing model eliminates compatibility risks and delivers precision not achievable with mixed-component systems.

TECDOS Drive Technology for Sluice Gates

The TECDOS Drive Technology builds on this foundation of calibrated chain engineering to deliver a robust, mechanical drive solution specifically suited to challenging sluice gate environments. TECDOS is a modular drive system that transmits force via a high-strength round-steel chain and precision-engineered drive units, such as the PI-GAMMA and OMEGA drives.

Unlike friction-based mechanisms or hydraulic systems, TECDOS relies on positive mechanical engagement. This ensures predictable, controlled movement under high static loads, variable operating conditions and frequent start-stop cycles, which are common in sluice gate applications. The cold-formed round steel chain offers exceptional strength, fatigue resistance and wear performance, making it ideal for wet, abrasive and corrosive environments found in water and wastewater infrastructure.

TECDOS is Ideal in Sluice Gate Applications

Sluice gates are hard on drive systems. Constant exposure to moisture, sediment, and challenging weather events can degrade standard rack-and-pinion drives, wire rope systems or hydraulic cylinders. These systems depend on friction surfaces, seals or fluid pressure, which can lead to variability, leakage and higher maintenance requirements over time.

TECDOS drive systems are engineered to minimise these failings. With fewer wear-prone interfaces and a mechanical load path, the system ensures consistent performance throughout its life. This is valuable in remote or difficult to access installations where maintenance opportunities are limited and downtime is costly. TECDOS systems are suitable for vertical lift gates, horizontal slide gates, isolation gates and flood protection gates and support linear, vertical, horizontal or inclined movements.

How does RUD TECDOS Drive help in sewage treatment plants?

Modern sewage treatment plants place extreme demands on mechanical drive systems and selecting the right drive technology is critical to achieving reliable, continuous operation in clarifiers, grit chambers and grease removal systems.

Modern sewage treatment plants operate in some of the harshest mechanical environments. Constant moisture, abrasive solids, corrosive gases and variable loads place extreme demands on drive systems used in clarifiers, sand traps and grease filter separators. Reliable, purpose-built drive technology is critical to ensuring stable and continuous plant operation. RUD’s TECDOS Drive Technology has been developed specifically to meet these challenges in sewage and wastewater treatment applications.

The Role of Drive Technology in Clarifiers

Clarifiers are large settling tanks that use gravity to separate solids from liquids. They include large scraper bridges that rotate continuously to collect settled sludge and move it into collection hoppers. Surface skimmers remove floating scum from the water surface.

The drive system powering this slow moving, high torque mechanism must operate with minimal vibration in outdoor installations exposed to sun, rain and dust.

TECDOS drive systems utilise high-performance round steel chains as the primary transmission mechanism, replacing conventional gear racks or friction-based drives. The chain based technology ensures consistent power transfer, calibrated movement and superior resistance to shock loads. The fixed head PI-GAMMA drive configuration ensures smooth and stable operation of scraper bridges under varying load conditions, contributing to longer service life and reduced operational disruptions.

Unlike traditional open gear drives, TECDOS components are designed with weatherproof construction and corrosion resistant materials, ensuring trouble free operation in permanently wet and chemical environments. This makes TECDOS ideal for circular and rectangular clarifiers in council sewage and industrial wastewater plants.

TECDOS® Systems

At the core of every TECDOS solution is a quenched and tempered round steel chain. RUD chains are engineered for exceptional dynamic strength and wear resistance, offering long service life in heavy duty drive applications.

Each chain is traceable through standard 3.1 inspection certificates, supporting material quality assurance and process safety compliance.

TECDOS systems are supported by engineered components designed for strength, alignment and serviceability, including:

This modular TECDOS drive system can be adapted for both new installations and retrofit projects in existing sewage treatment plants.

Benefits of TECDOS Drives in Clarifiers

The key advantages of TECDOS technology in clarifier applications include:

Applications in Sand Traps (Grit Chambers)

Sand traps, also known as grit chambers, are designed to remove heavy inorganic particles such as sand, gravel and small stones from incoming wastewater. These highly abrasive materials cause rapid wear in conventional mechanical drives.

TECDOS OMEGA drive systems are well suited for grit removal equipment. With a chain loop angle of up to 180 degrees and options for fixed or mobile drive arrangements, the system delivers reliable power even under high resistance load conditions. This delivers efficient grit removal, protects downstream equipment and reduces overall plant lifecycle costs.

Advantages for Grease Filters and Scum Removal Systems

Grease filters and scum removal mechanisms primarily handle floating fats, oils and grease (FOG). These substances are sticky, chemically aggressive and difficult for conventional drive components. TECDOS drives eliminate many slip and corrosion related problems through a chain based positive drive principle. Because power is transmitted mechanically via high strength steel chains rather than friction-based systems, performance remains stable even when exposed to oily and greasy residues.

This reliability enhances overall process stability and enables treatment plants to maintain compliance with discharge regulations.

TECDOS Advantages for Treatment Plant Operators

Beyond individual applications, TECDOS drive technology supports broader operational goals of modern sewage treatment plants:

The ability to deliver complete system solutions, including motors and customised mounting arrangements, simplifies project engineering and installation.

Why Chain-Based Drives Are Replacing Traditional Systems

Traditional clarifier and scraper bridge drives have often relied on rack-and-pinion systems or friction wheels. While these solutions can be effective under ideal conditions, they are vulnerable to accelerated wear, slippage and misalignment in real world wastewater environments.

TECDOS round steel chain drives provide positive mechanical engagement with proven, long-term performance. This is particularly critical in large diameter clarifiers, where uniform power distribution and high reliability are essential for process efficiency.

The Final Word

TECDOS Drive Technology is a modern, purpose-built solution for the mechanical challenges of sewage treatment plants. When used in clarifiers, sand traps and grease filters, the system delivers high torque capacity, superior resistance to wear and corrosion and outstanding operational reliability.

By combining high performance round steel chains with robust, modular drive systems such as PI-GAMMA and OMEGA, TECDOS enables improved system uptime, reduced maintenance costs and stable, predictable process performance.

Submerged Scraper Conveyors (SSC) play a vital role in handling hot, abrasive materials safely and efficiently across industrial operations. At RUD Australia, our advanced conveyor systems, built on decades of engineering innovation, deliver reliability, cooling performance and environmental compliance across demanding industries such as power generation, mining and waste-to-energy.

Submerged scraper conveyors (SSC) are the commonly used ash handling systems designed to move hot, abrasive bulk material through a water-filled trough. These systems are primarily used in coal based thermal power plants because they provide a reliable and environmentally friendly option for handling materials such as boiler ash. Unlike dry conveyors, the SSC operates in a water bath, a design that not only quenches the material but also suppresses dust. This mechanism enables safe handling of high-temperature materials while supporting compliance with environmental requirements.

How Submerged Scraper Conveyors Operate

A typical SSC uses a continuous wear resistant round case hardened steel link chain with scraper bars fitted with multilink attachments that travel along the floor of a steel trough filled with water. Ash is conveyed by an upper strand in the water filled tub. As the scraper bars move the ash toward the outlet, the trough’s inclined section raises the material out of the bath for discharge. Chains run over idlers, shafts and submerged overhung idlers (SOI). SOI are partly equipped with control facilities to monitor the operation and is a critical component in the system.

The water in the trough serves two primary functions: it rapidly cools the incoming ash and acts as a barrier to airborne dust. Once the scraper flights leave the submerged section, gravity allows excess water to drain from the conveyed material before it reaches the storage or processing area. The treated water is then either recirculated or disposed of in accordance with site water management procedures. Only the part of the conveyor above the intermediate bottom is filled with water, while the return strands run on dry wear rails.

Advantages of SSC Technology

Submerged scraper conveyors offer several advantages that are relevant in power generation and other high temperature applications.

Efficient vertical transport systems are crucial for industries that manage bulk materials such as agriculture, mining, and cement production. RUD Bucket Elevators are ideal and reliable vertical conveying systems to move materials safely and effectively with a low maintenance cost.

This article explains the benefits and applications of bucket elevators and the manufacturers across various industries. We also discuss how RUD can help choose the most appropriate bucket elevator suited to your requirements.

Types of Bucket Elevators

Bucket elevators come in two types: Chain and Belt. They transport bulk materials such as raw meal, dry dust, cement, etc., at various temperatures. The buckets are fixed to a chain or belt, conveying materials from the loading point to the discharge point in a vertical configuration. The system is enclosed, minimising material spillage and dust generation. The bucket elevator casings are self-supporting but require horizontal guides at least every 15 meters and below the elevator head.

Benefits of Bucket Elevators

Vertical Conveyance: RUD bucket elevators move large volumes of bulk materials vertically. This is beneficial to grain storage companies because the grains can be moved into silos without compromising the speed or capacity. Similarly, in mining, RUD elevators ensure the smooth movement of crushed ore through processing equipment

Strength and Durability: RUD bucket elevators are manufactured from wear-resistant components. In chain bucket elevators, chains provide the required strength to handle heavy and abrasive materials at higher temperatures. Whether moving crushed stones, ores, or coal in mining, or transferring grains or raw materials in cement plants, chain bucket elevators are built to withstand extreme conditions with minimal downtime. Textile or steel reinforced belt bucket elevators are ideal to transport free-flowing bulk materials, dust-free, in a continuous vertical conveyance to significant heights

Reduced Maintenance and Operational Costs: RUD bucket elevators can operate at peak efficiency with minimal maintenance and downtime. Chain elevators are inherently hard-wearing and resistant to wear and mechanical damage. Their unique design requires minimal lubrication and virtually no maintenance, leading to lower operating costs, reduced downtime, and extended system life. This cost-effectiveness is critical in industries like gas and cement manufacturing, where continuous production is required

Versatile Applications: RUD Bucket elevators can be adapted across numerous industries, including:

This versatility makes RUD bucket elevators an essential equipment for which bulk material handling is a priority.

Improved Safety and Environmental Protection: Safety and environmental factors are critical in the cement and mining industries, where dust poses health or contamination risks. With their enclosed structure, RUD bucket elevators minimise material spillage and dust emissions. Additional safety features, such as speed governors, overload protection and emergency stop functions, further ensure employee safety

RUD will display the TECDOS MSB (Multi Station Bench) at the Nonnenmann booth at the Molding Expo in Stuttgart from 6 to 9 May 2025. Nonnenmann is a reputable provider of mould solutions, and the Moulding Expo serves as a key gathering for companies across the tool, modelling, and mould-making industries.

Designed as an all-in-one solution, the TECDOS MSB simplifies the maintenance process for tools and moulds.

"This is brand new to the market: a single device capable of performing all the crucial steps in handling moulds and tools weighing up to 2.5 tonnes - including opening, turning, maintenance, and testing. While similar comprehensive solutions have existed, they were previously only available for heavy-weight categories," explains Anne Kühling, Product Manager for Conveyor and Drive Systems at RUD. "The new MSB station fills this gap, catering specifically to lighter, more compact tools and moulds."

All-in-One Tool Handling

The RUD TECDOS MSB maintenance station is based on the robust RUD TECDOS TMB industrial workbench, featuring an integrated turning table (120 x 80 cm). This design ensures that the tools are safe and ergonomic, turning up to a 2.5-tonne capacity, achievable with just a standard cordless screwdriver. Adding an opening function and a testing device transforms it into a comprehensive, all-in-one maintenance station. T-slot rails attached to one side of the tool turner securely hold the tool halves during manipulation.

A pneumatically supported plate allows operators to move moulds and tools weighing up to 2.5 tonnes easily and safely at the push of a button, enabling direct processing on the maintenance station. "The air cushion significantly facilitates the often-challenging initial opening of tools and moulds. Furthermore, the optional hydraulic unit for ejector tests allows even tool assemblies with backpressure pins to be opened," explains Jochen Schwegler, Application Technology Consultant at Nonnenmann GmbH, RUD's development and sales partner for the new station.

Streamlined Testing and Quality Control

The compact unit integrates easily into any factory or workshop. "Our experience and market feedback indicate that, due to time constraints, many moulds are installed directly into the machine without prior testing. If malfunctions occur later, for example, blocked temperature control channels, the entire mould must be removed for repair. This results in significant downtime and costs," emphasises Anne Kühling.

To prevent costly interruptions in injection moulding operations, the RUD TECDOS MSB allows operators to perform essential checks easily and quickly. This includes conducting ejector tests and leak tests of the temperature control channels directly on the station before machine installation.

Increased Occupational Safety and Ergonomics

Operating the TECDOS MSB is both ergonomic and safe, facilitating work practices that are compliant with stringent Work Health and Safety (WHS) regulations. "Dragging heavy loads across the factory floor with a crane or pulling them manually at awkward angles is not only unsafe but also contravenes fundamental WHS principles and safe work procedures," says Kühling. The RUD TECDOS MSB provides a safer alternative, reducing reliance on cranes, ropes, and potentially hazardous manual methods like using chisels for separation.

Broad Product Portfolio

Apron feeders are crucial components of material handling in many industries. Their robust construction and precise control capabilities make them uniquely suited for transporting challenging materials, such as high-temperature materials, in demanding environments.

Understanding the Mechanics of Apron Feeders:

Apron feeders are conveyors in which material is carried on overlapping steel plates, known as "aprons," that travel over sprockets, rollers, and gears. These components are fabricated from high-strength steel and designed to withstand significant wear and tear. Motors and gearboxes power the feeder, enabling controlled movement of the aprons and the material they carry. RUD apron feeders are connected by conveyor chains driven by a calibrated toothed pocket wheel.

The overlapping design of the plates is critical because it ensures smooth and consistent material flow while eliminating spillage. This feature makes apron feeders ideal for handling materials that are difficult to transport, such as:

Advantages of Apron Feeders:

Cement asphalt plants use bucket elevators to move the material to the plant mixing tower. Bucket elevators used in asphalt plants should withstand high material temperatures (frequently reaching 180-200°C) and operate at high capacity (e.g. up to 100-200 tonne/hour).

An asphalt plant in South Australia had operational capacity problems and frequent DIN bracket-type bucket elevator system breakage. The plant was only producing 85,000t annually, which was quite low compared to the standard 100t per hour over a 2,000-hour system life (200,000t per year). In addition, they experienced significant downtime due to replacing the chains and brackets every 8-12 months, negatively impacting their efficiency and throughput.

The Challenges with the Current System

The current system had a few shortcomings, such as:

In comparison to the short life of the DIN system, RUD endless chains only need to be replaced after producing approximately 200,000t. The bucket attachments, however, can be replaced after approximately 400,000t, which was a huge advantage to the plant. The RUD system is superior, with endless chains and bucket attachments, doubling the chain life and increasing component life by four times.

Description of the problem: 

The chain contact with the DIN shackles was wearing out faster in the interlink area because it had lower hardness. The wheel diameter was also too small for optimal chain life.  All the centrifugal load was applied on the bucket shackle as it moved around the wheel, resulting in higher interlink wear.

Some of the issues the plant was facing were:

Why did the client approach RUD?

Most bulk material handling sites in Australia using the DIN shackle system are gradually being replaced with the RUD 2WIN solution. The 2WIN system has a 3-link interlink contact, which makes conveyors more stable and provides longer component life.

The client was aware that RUD had successfully completed many upgrades of 2WIN conversions, so they invited RUD to propose a full conversion plan.

Some of the reasons for approaching RUD were:

The RUD Solution:

RUD implemented the 2WIN solution with a 3-link contact with the 19x75 chain, making the conveyor stable even on smaller-diameter wheels. This included replacing the treads with hardened wheels which fitted the existing casings. The treads were a bolt-on design for easy installation and replacement when required. The added benefit was that the capacity could be maintained or even increased with bucket spacing on a 19x75 chain.

RUD bucket elevator systems offer a range of proven, high capacity and flexible solutions for all vertical handling applications. The hardened steel chain systems support large capacity conveying, providing maximum throughput.

The Result:

Regular chain wear measurements will be monitored with a service and support plan to maximise chain life and performance. We use predictable life projections for scheduled maintenance to avoid unplanned downtime. Most of our component kits are planned and delivered well before a shutdown. Backup kits are supplied before planned outages to avoid unscheduled downtime.

A Win-Win Situation

The RUD 2WIN system ensures efficient operation in the demanding hot asphalt environment for many years. The 2WIN attachment, fixed on the bucket, distributes load, and extends the bucket lifespan. Additionally, these attachments are replaced only with every second chain change, maximising efficiency. Full tensioner wheel contact minimises tread wear and extends chain life. The hardened RUD components are superior to the previous wheel, and the treads only require changing every second chain set.

This upgrade with the 2WIN system is a WIN-WIN for both RUD and the client.

Why should you use RUD bucket elevators?

Increased Efficiency

RUD bucket elevators are designed to increase efficiency in mining, power plants and fertiliser plants. By using RUD Chains, the bucket elevators can convey more materials over a short distance than traditional conveyors. They also allow for quicker loading and unloading of materials compared to other elevators. This helps to save time and money, as well as reduce downtime. The high capacity and efficient performance of these elevators makes them the perfect choice for any industrial application that requires reliable and efficient material movement.

Reduced Maintenance Costs

RUD bucket elevators are designed to reduce maintenance costs and increase efficiency. They offer a range of advantages over traditional conveyor systems, including decreased downtime. RUD chains provide superior strength and durability, ensuring that buckets remain secure and upright throughout the elevator's lifecycle. This reduces the need for frequent repairs and replacements, leading to significant savings in maintenance costs. Additionally, RUD chains are made from low-maintenance components, with no need for regular lubrication or adjustment. This further reduces the overall cost of ownership in mining, power plant and fertiliser plant operations.

Increased Capacity

RUD bucket elevators offer an efficient and reliable way to transport materials over long distances or at high capacities. By using RUD chains, the elevators can lift up to 90kg per chain link, providing a strong and reliable system with high throughput. This makes them the perfect choice for transporting materials in power plants, fertiliser plants, and other industrial applications. With the ability to easily handle large volumes of material, RUD bucket elevators can significantly increase production output, reduce downtime, and improve operational efficiency.

Improved Safety

RUD bucket elevators are designed with safety in mind. RUD Chains have a built-in protection system that prevents unauthorised access to the drive system, providing an additional layer of safety when handling heavy loads. The chain is designed with a breakage detection system that automatically stops the elevator and alerts personnel if there is an unexpected increase in the chain tension or an unexpected decrease in chain speed. This ensures that the chain and any material being moved are always under control. The guard rail system also helps safe operation by personnel, preventing accidental contact with the running chains and come equipped with emergency stop buttons.

Large industries in bulk material handling require safe and efficient methods of conveying materials with minimal risk of spillage. Selecting the right conveyor for the process depends on factors such as type of the bulk material, location of the feeding and discharge point and other special requirements such as mixing, hygiene, toxicity in the process, etc.

Bucket Elevators are an ideal method of conveying bulk materials which require vertical elevation. Bucket elevators can handle a wide variety of bulk materials and can be manufactured with steel which offers resistance against abrasion. They also can be completely enclosed, minimising pollution from toxic materials and dust.

RUD is a pioneer in the conveying industry and RUD bucket elevators are sought after world-wide. Some of the advantages of the RUD bucket conveyor systems are:

RUD chain bucket elevators can handle high temperature, abrasive, sticky or sharp bulk materials, compared to belt elevators.

The various types of RUD bucket elevators are:

Round link chain bucket elevators

These are predominantly used for conveying of powdery, granular, lumpy, and temperature-loaded bulk goods. The highly wear-resistant RUD chains and sprockets ensure reliability with abrasive materials. Depending on the application, chain bucket elevators are available in special designs with a constricted chain of buckets or with a central discharge.

Central chain bucket elevators

These are ideally suited for large capacity conveying of coarse dry bulk goods and offer maximum conveying reliability, even when handling charge fluctuations, high-temperature materials, and materials with large single edge lengths.

Belt type bucket elevators

These bucket elevators use textile or steel reinforced belts to transport materials in a continuous dust-free vertical process. Suitable adaptations can be done to handle coarse-grained or higher temperature materials.

Maximum Capacity, Tough Applications, Proven Design

TECDOS CHAINS

Highly wear resistant for maximum safety

The core component of each TECDOS drive system is a highly wear-resistant, calibrated round link chain which can be used in adverse conditions or with abrasive materials. TECDOS chains have high grade strength to ensure maximum operating safety.

There are 2 types of chains which can be used for a wide range of requirements and applications:

TECDOS CHAIN CONNECTOR

For a reliable connection

TECDOS chain connectors help to connect chains and create a safe connection system. Connecting is easy because the overall dimensions are the same as the chain links. They can be used in both single and multi-strand conveyors, operating in medium to heavy duty conditions.

The advantages of CHAIN CONNECTOR:

TECDOS POCKET WHEEL

To complement TECDOS chains

TECDOS pocket wheels are designed to work with TECDOS chain and are available for single and multi-strand configurations from TEC 6 to TEC 260 sizes and for loads from 6 up to 260 kN.

The advantages of POCKET WHEEL:

TECDOS LIFT LIMITER

The lift limiter prevents the chain from “passing through” by limiting the unloaded sides of the chain, working as a route limiter.

TECDOS SLINGS

The TECDOS sling and lashing systems are available in various products such as:

TECDOS systems are ideal for applications where materials or equipment need to be swivelled, lifted, moved, or rotated safely and reliably. RUD quality is a result of years in research and development, creating bespoke drive solutions that are used by leading companies in maritime, engineering, automotive, wind power and by military forces around the world.

Part 1 of a 2 part post.

RUD has been a manufacturer of lifting chains for more than 140 years which are used in chain hoists across the world. In the course of its innovative journey, RUD developed a drive system by combining high quality and accurately calibrated steel chains to fit into complementing sprockets called TECDOS.

TECDOS modules are suitable for high loads and can be installed anywhere. They are an ideal replacement for pinion gear and wire rope drives. The biggest advantage of the RUD TECDOS systems is their reliability to work under the most difficult conditions. TECDOS is used across offshore and onshore projects, ports, jetties, mining, hydraulic steel engineering, entertainment, steel construction and shipbuilding. It is also used to move roofs insports stadiums, swimming pools, spa pools or event venues.

Watch the sliding roof video below:

Some of the components in the RUD TECDOS drive system are:

TECDOS OMEGA DRIVE

For linear or rotating movements

The TECDOS OMEGA drive with a loop angle of 180 degrees is suitable for both continuous linear and rotational movements. OMEGA drive is used in onshore and offshore projects to move cranes, align, and adjust loaders and to open and close cargo space covers on ships. When rotating, the OMEGA drive can also be used to lift and lower platforms, drive ferries, and extend telescopic booms and skidding systems.

The advantages of OMEGA DRIVE:

TECDOS PI-GAMMA DRIVE

For horizontal and vertical systems

PI-GAMMA drive system with a fixed 180-degree angle (PI) or a flexible angle of 90-180 degrees (GAMMA) is suited for horizontal and vertical applications. The PI-GAMMA pocket wheel block can pull the load along the round steel chain or move it to a different location.

Some of the uses of PI-GAMMA DRIVE are:

Innovative Fertiliser Conveying Solutions by RUD

RUD Australia, the subsidiary of the German-based RUD Group, has been providing innovative conveying solutions for various industries since 1984.

Large projects, commercial operations and complex industrial environments benefit significantly from conveyor systems. The use of conveyor systems helps mitigate the risk of damage or loss to materials being handled. This enables the efficient mechanised handling and transport of materials. Conveyors are particularly useful in challenging industrial settings where there are sizeable workloads and extreme weather conditions considered adverse or unsafe for human labour.

Among the conveying solutions RUD is known for include spillage drag conveyors, apron conveyors, chain-driven belt feeders, bucket elevator conveyors and floatation tank conveyors.

In particular, RUD has developed optimal solutions designed to address the need for safe and efficient conveyor systems in the transport of fertiliser.

Unique challenges

During bulk handling and transport, there are ever-present difficulties that industries need to anticipate. These include dust, contamination, and spills that usually occur at the transfer points of conveyor systems. Moreover, there are other problems to look out for, such as abrasion, belt misalignment and damage.

However, what makes fertiliser handling and transport particularly challenging is the added burden of the fertiliser being sticky and moist – thereby posing additional complications to the handling process.

But with RUD’s engineered fertiliser conveying solutions and systems, dust formation, material spillage and the risk of explosions occurring in critical transfer sections are minimised significantly. Moreover, the chance of any misalignment, abrasion and belt damage happening is effectively eliminated.

Fertiliser conveying solutions up to the task

RUD’s innovative fertiliser conveying solutions include belt bucket elevators and spillage drag conveyors.

Bucket elevators 

RUD bucket elevators enable the safe, quick, precise and efficient vertical transportation of fertiliser, cement, sand, gravel, potash and salt.  Quality componentry reduces downtime and allows for maximum efficiency.  Read more about this solution.

Spillage drag conveyors 

The heavy-duty, low-maintenance RUD spillage chain conveyor system is built to ensure efficient fertiliser transport in low-profile, reduced-access applications. Spillage chain conveyor systems can be fully enclosed, thereby enabling the safe, dust-free and watertight transport of bulk fertiliser material. Find out more.

Chain-driven belt feeder conveyors 

Our chain-driven belt feeder conveyors are designed for optimum productivity through a completely waterless operation, with the assurance of safety even when processing hazardous waste.  This system allows you to process solids faster and is suitable for both horizontal and inclined operations.
