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 tohigh 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:
High-performance chain wheels for controlled power transmission
Chain guides to ensure precise alignment and low wear
Special chain end attachments designed to transfer 100% of operating forces
Flexible attachment points that accommodate structural tolerances and alignment variations
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:
High reliability in continuous operation - Clarifiers typically operate 24/7, and TECDOS chains and drive heads are engineered for continuous service, reducing unplanned downtime
Smooth, vibration free rotation - The PI-GAMMA fixed head drive design ensures uniform power transmission, reducing mechanical stress on scraper bridges and structural components
Low maintenance requirements - Wear resistant materials and protected drive elements reduce inspection frequency and component replacement
Resistance to weather and corrosion - Critical components are designed to withstand dirt, moisture and corrosive substances commonly found in wastewater treatment environments
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:
Reduced unplanned downtime through durable and fatigue-resistant components
Improved plant availability through simplified inspection and maintenance routines
Safe operation supported by robust mechanical design and proven industrial standards
Flexible integration with motors from different manufacturers
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.

Western Australia's maritime industry faces unique challenges, particularly with vessel access due to the region’s extremely high tidal ranges, which can reach up to 11 meters. These high tides complicate the boarding process from jack-up barges or jetties, posing safety risks to personnel and impacting operational efficiency. Traditional methods of vessel access often prove inadequate and potentially unsafe in these demanding environments.
This is why the RUD TECDOS system is recommended as an ideal solution.
Exceptional durability:
The extreme conditions of Western Australia's coastal waters require equipment designed for exceptional durability and reliability. The RUD TECDOS system is ideal because it is resistant to corrosion and engineered for long exposure to seawater, contamination, and environmental wear and tear arising from the constant buffeting of waves. TECDOS systems ensure long-lasting performance even in the most challenging environments.

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:
Low chain hardness: Forged chain links were wearing faster due to lower hardness.
Small wheel diameter: The small wheels did not fit the chain size, accelerating wear in the interlink area.
Single-link contact: Each wheel rotated and pivoted the bucket on a single link, concentrating the centrifugal load and causing high interlink wear.
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:
High temperature - Resulting in the tempering of the forged shackles.
Head wheels getting worn - Because they were non-hardened.
High link wear due to the small diameter of the wheels and single link contact.
Noisier operation due to chain and shackles not being matched. For example, an 18mm chain was used for a 20mm shackle.
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:
Limited availability: The original 20mm shackles required frequent replacement and became difficult to source globally.
Enhanced chain performance: The 19x75 chain spacing offered improved pitch length and higher hardness (82hV, a 10% increase).
Superior hardening: Continuous chain case hardening provided significant advantages over existing chain hardness.
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.
Increased Efficiency - Ultra-hardened chain R100 chain systems handle larger capacities and process more material.
Easy Adaptability - Perfect for a lump or granular material.
Simplified Maintenance - Easy access casings facilitate fast replacement of teeth, treads, and wheel segments.
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.

Ensuring a safe and controlled operation is critical in the challenging conditions of marine projects. Marine environments are corrosive and heavily influenced by currents and tides. Hence, it is paramount that all factors are considered before installation to ensure long-term performance.
This article discusses the reasons why the RUD TECDOS drive solution was ideal for the Brisbane River Ferry Terminals.
The Challenge: Decoupling Walkway in a Marine Environment
International Consulting Engineering company Aurecon approached RUD seeking a drive solution to decouple the Brisbane River Ferry Terminal walkways. The biggest challenge was enabling controlled release and rotation of the walkway undercurrents and tides and preventing damage caused by the ebb and recess of the water flow.
Why TECDOS? Addressing Key Requirements
RUD invited Aurecon to a site visit to the Brisbane factory to demonstrate and showcase the capabilities of the RUD TECDOS system.
RUD TECDOS possessed several benefits that aligned with the project's specific requirements:
Corrosion Resistance: The zinc-coated RUD TECDOS chain is specially designed to withstand challenging marine environments, ensuring long-lasting performance without rusting even in a static position.
3D Flexibility: The inherent flexibility of the TECDOS chain allows for smooth and controlled movement of the walkway, accommodating slight misalignments while maintaining structural integrity. This is crucial for ensuring proper engagement and release during operation.
Compact Design: Compared to conventional wire rope cables, the TECDOS system utilises compact wheels with six pocket teeth, minimising space constraints within the terminal design.
Static Functionality: The system is designed to remain idle in a static position until decoupling is required. This ensures minimal wear and tear on the components during normal operation, extending their lifespan and reducing maintenance needs.
Accurately Rated Load Capacity: The TECDOS system offers accurately rated load capacities, ensuring the safe and reliable handling of the walkway under various load conditions, including potential debris accumulation or high water levels.
Click for more details of TECDOSPi-Gamma Drive and Omega Drive technology and why RUD is the world leader in drive technology based on the RUD round steel chain mechanism for horizontal, vertical and rotational applications.
The RUD Solution: A Controlled and Safe Decoupling Mechanism
The implemented solution leverages the TECDOS chain drive system to achieve a controlled and safe decoupling process:
Chain Release with Damping: The mechanism utilises the TECDOS chain to control and lift the rotating gangway (walkway support structure) away from its cradle through a dampener system. This dampener ensures smooth lifting motion, preventing sudden movements and potential damage.
Controlled Decoupling and Rotation: The control arm is integrated with the TECDOS chain to facilitate the lifting and subsequent release of the walkway. This allows the walkway to rotate controlled, aligning it with the downstream river flow to prevent damage during high tides, which increase water levels.
The Result: A Proven and Replicable Solution
The success of the RUD TECDOS implementation at the Brisbane River Ferry Terminal is evident by:
Multiple Installations: We have installed the TECDOS drive solution in seven ferry terminals across Brisbane. Each terminal uses nine TECDOS six-tooth pocket wheels, chains, and terminations per unit. Each unit features a fixed pocket wheel connected to the dampener for controlled speed and additional wheels facilitating lifting and releasing the gangway.
Operational Success: The fully fabricated and controlled system is operational across all seven ferry terminals, demonstrating its effectiveness in safely managing walkway decoupling during high tides and debris during flooding.
Watch the video of the engineering and design from Aurecon, which ensured an ideal option to ensure the critical ferry infrastructure is flood resilient, accessible and for travellers to enjoy and celebrate the river.
Conclusion: Addressing Marine Challenges with Innovative Solutions
The RUD TECDOS system on the Brisbane River Ferry Terminal demonstrates its versatility and effectiveness in addressing complex challenges in the marine sector. Its corrosion resistance, 3D flexibility, compact design, and precisely rated load capacity make it an ideal solution for applications requiring controlled movement and reliable operation in challenging environments.
In addition, the system's modular design and proven track record across multiple installations highlight its potential for wider implementation within the conveying and drive sectors, where accurate control, corrosion resistance, and space optimisation are critical considerations.

Christmas is the season for kindling the fire of hospitality - Washington Irving.
Christmas is doing a little something extra for someone. It is the season of giving, and who better to talk about giving than a charity? Our December Charity Champion is Sallyanne, who is very passionate about giving to the community through the #BeAnElf organisation.
The#RUDstory is about our employees, the charities they support each month, the values they hold dear, and their experience of teamwork, challenges and motivation at RUD.
How many years have you been involved with the Be An Elf charity?
I have been supporting the BE AN ELF charity for 6 years, and RUD Chains has been participating for the last 5 years. This is my favourite charity which I support as I love doing the shopping and giving back to the community.
What inspired you to continue advocating for this charity?
My children have been very fortunate to receive gifts on Christmas morning, and I wanted to teach my children to give back to the community. The Byrne family has been part of the BE AN ELF charity for the last six years, and we love making some local children happy on Christmas Day. This is RUD’s fifth year supporting the charity, which is exciting. One thing I love about this charity is the “Elves” deliver the gifts on Christmas Eve so the children receive their gifts on Christmas Day.
Why is this charity important to you?
I think the big smiles on the children say it all. Being given the gift ‐ granting the very longed-for item and brand from the top of their Wish Letter to Santa' is incredible. We've gone and done it ‐ granted that first wish ‐ bought a new pair of black school shoes, the next Wish Letter for a most desired Barbie, then a really longed-for 'new undies' that weren't holey and pre-worn. RUD and I want to make a difference, contribute to our local community and put smiles on children's faces.
How does the charity serve the community?
For the last 16 years in December, BE AN ELF volunteers read letters written by children to Santa and arrange gift bags for distribution. The letters are mostly written by local kids or their mums or dads asking for 'new shoes', ' bed sheets’, ‘pillow' or other necessities. The children are referred from services such as Centre Link, Social Workers, Neighbourhood Centres, Family Services and GP’s. The BE AN ELF mission is to put smiles on the faces of less fortunate local Queensland kids on Christmas Morning. When times are tough, it’s the little people who are struggling that suffer the most, and being different can be a hard lesson to learn.
How does the RUD team help with the cause?
The difference we make at RUD through the BE AN ELF is an empowering contribution to society’s vulnerable and smallest members who, most of the time, end up neglected because they do not have a voice.
Any additional comments?
I love contributing to this cause, and every year RUD contributes more wish letters which makes me so proud to work alongside such generous people. All for the same cause of making Christmas the most magical day of the year for all.
We are always looking for people in engineering, fabrication, welding, sales or marketing who believe that customers and culture are important. If there are no suitable roles,click hereto send us an expression of interest.
A gangway is a narrow walkway or platform that provides safe access to a ship, truck, or train. Ship gangways are used for the passage of both passengers/crew and cargo. They must move in all directions and be height-adjustable for use with different ships. The gangways must also be robust, secure and safe under challenging conditions.
RUD’s TECDOS Drive system offers an ideal solution for a gangway, using calibrated steel chains fitting into complimenting sprockets. TECDOS drive systems are an ideal replacement for pinion gear and wire rope drives because they function reliably even under the most challenging conditions.
For gangways, RUD TECDOS drive systems can include:
TECDOS PI-GAMMA DRIVE
The PI-GAMMA drive system, with a fixed 180-degree angle (PI) or a flexible 90-180-degree (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.
The advantages of PI-GAMMA DRIVE:
Ideal 2-in-1-solution.
Light and can be used in narrow spaces.
Can be used between a 90° and 180° redirection or a total 180° redirection.
Multiple lifting points.
Durable, reliable, and safe.
Easy installation without the need for a stable mounting base.
TECDOS PREMIUM ROUND LINK CHAIN
The core component of each TECDOS drive system is a highly wear-resistant, calibrated round link chain that can be used in challenging conditions or with abrasive materials. TECDOS chains have high-grade strength to ensure maximum operating safety. The Premium Round Link Chain is case-hardened.
TECDOS END CHAIN FIXING
The chain end fixing, which connects chains to supporting structures, transfers 100% of the TECDOS chain operating forces. Because of its adjustable axis, it also ensures maximum flexibility during use.
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.
The Project:
RUD Australia was approached to build a passenger gangway for a cruise ship terminal in Western Australia. The client could not implement the standard method of using a hydraulic cylinder, as it was too expensive and not cost-efficient for the required lift height.
The Solution:
After understanding the project's scope and the solution that best met the client's requirements, RUD developed a dual-strand loop drive component package for this project.
The Result:
RUD implemented a TECDOS 65 component package. Gear motors independently drove the Pi Drives.
The Project Inclusions:
2 x TECDOS 65 PI-GAMMA DRIVE
2 x TECDOS 65 HEBG END FASTENER
34m TECDOS 65 PREMIUM CHAIN
2 x POWERPOINT PP-VIP M36
2 x TECDOS 65 SPECIAL BOLT
2 x TECDOS 65 POCKET WHEELS
TECDOS systems are ideal for applications where materials or equipment must be swivelled, lifted, moved, or rotated safely and reliably. RUD quality is a result of years of research and development, creating bespoke drive solutions that are used by leading companies in maritime, engineering, automotive, and wind power and by military forces around the world.

Entertainment is big business. All musical and sporting events require smooth behind-the-scenes operations to create magic for the audiences. Many stadiums, opera houses and theatre buildings are constructed or renovated to accommodate a wide variety of events, from sports to live theatre, music concerts and dance performances. Hence, the stage needs to adapt quickly to new areas or shapes to accommodate the demanding requirements of such events. And the only way is by using systems such as mechanical chains that lift, lower, push, and pull equipment into a variety of configurations.
Every stage is different, which means that each component of the stage not only has to be durable and efficient but must also integrate into the whole equipment. Theatre and stage construction present technical challenges because of high loads on crossbeams, stage lighting, stage sets or entire stage platforms, which must move safely and reliably. In addition, technical equipment must operate quietly and out of sight, so as not to interfere with the performance.
A long history
RUD has been a world leader in lifting and drive technology with a history of manufacturing excellence for over 140 plus years.
The magic of a show is priceless. Many opera houses, theatres and stadiums across the world use RUD hoist chains and drive solutions that reliably raise and lower stage equipment such as crossbeams, platforms and curtains including setting up and dismantling shows. RUD chains and drive solutions also enable the smooth realignment of permanently installed lightning. Every event is unique and using RUD chains and drive technology guarantees a safe and easy process including customisation for each performance as required.
TECDOS from RUD is a drive system that combines high-quality and accurately calibrated steel chains which fit into complementing sprockets. TECDOS modules are suitable for high loads and reliable under the most challenging conditions. Every TECDOS round steel chain is stamped and issued with a standard 3.1 inspection certificate to ensure its traceability right back to the chain furnace.
Solutions for the entertainment industry:
All RUD products are finished in Galvanised Black Phosphate to blend with the stage equipment.
CASE-HARDENED ROUND STEEL CHAINS
Case-hardened RUD chains of RTS, RTD and RTB are the safe option for every electric hoist which require reliability and safety.
The benefits of RUD Case-Hardened round chains are:
They can be used in high-wear applications as per DIN EN 818-7-T.
They have a high vibration resistance which helps to resist fatigue fractures during operation.
D-PROFILE CHAIN
RUD D-profile chain, the round steel chain 2.0, is the leading technologically advanced round steel chain. Because of its large cross-sectional area, it has a higher maximum load, is case-hardened and designed for higher wear demands.
The benefits of RUD D-Profile chains are:
Used for motor-driven hoists.
Used in high wear loads in accordance with EN 818-7-T.
Has approximately 8% higher load capacity than comparable round steel chains.
TECDOS DRIVE TECHNOLOGY
RUD TECDOS products can manage the lifting and moving of all stage elements, safely and reliably.
Some of the TECDOS products used for stage operations are:
TECDOS ROUND LINK CHAIN: The core component of every TECDOS system application is a highly wear-resistant RUD round link chain for maximum service life.
TECDOS PI-GAMMA: The 2 in 1 Pi-Gamma is suited for horizontal and vertical applications with a fixed 180 degree application, or a flexible 90 to 180 degree application. The drive system ensures greater efficiency through flexibility.
TECDOS OMEGA DRIVE: TECDOS Omega Drive with a wrap angle of 180 degrees is recommended for continuous linear (linear drive) or rotary movements.
TECDOS Pocket Wheel: TECDOS pocket wheels are optimally designed to fit round link chains for smooth running and long service life.
TECDOS Chain Connector: The highly wear-resistant chain connector forms a reliable connection system even under challenging conditions. Endless chain loops are possible by means of a simple hammer assembly.
TECDOS Chain End Fixing: The chain end fixing for connecting chains to supporting structures transfers 100% of the TECDOS chain operating forces. Due to its adjustable axis, it ensures maximum flexibility during use.
TECDOS PowerPoint Lifting Point: The PowerPoint lifting point for connection to chains, hooks, and eyes, can easily be rotated 360° and swivelled 230°. The double ball bearing ensures easy tilting, turning and rotating for drive technology.
