Rudolf Fuka GmbH: Los fabricantes de herramientas

Esta empresa con sede en Colonia lleva más de un siglo creando soluciones que otras no ofrecen; por eso, esto no es una estrategia de nicho, sino una filosofía.

por Sascha Göbel, EW Europe Corresponsal

Rudolf Fuka GmbH from Cologne, Germany, is not an elevator company in the traditional sense. No technicians on call. No maintenance contracts. Instead: mechanical engineering. Components. Systems. The tools that enable other companies to do what they otherwise couldn't – keep older systems safe, keep paternoster elevators running and implement retrofits that no one else on the market offers.

Your author knows FUKA from their drive pulleys: Anyone in need of drive pulleys from an independent market source quickly comes across this company. FUKA keeps a wide variety of gray cast iron drive pulleys in stock and also helps with particularly unusual designs – its catalogue with order-specific parameters is comprehensive.

On May 26, I met with Torsten Fuka, Birgit Zaunegger and Rudolf Fuka at their facility in Cologne-Ossendorf. What I took away from the visit was an understanding of how a family-owned business remains relevant across four generations – not through growth at any cost, but through precision in identifying the problems it truly aims to solve.

From Hartmann to Fuka: 100 Years of Mechanical Engineering

Founded in 1924 in Cologne-Ehrenfeld, the company – initially called Hartmann Maschinenbau – had a machine park that enabled contract manufacturing: turning operations, precision parts, deep craftsmanship. The company, which today operates under the name Rudolf Fuka GmbH and supplies customers throughout Europe, has evolved far beyond these beginnings – without denying them.

The company was founded more than 100 years ago as a machining shop. Alfred Hartmann, who became a father figure to young Rudolf Fuka Sr. after his biological father's death, passed the company on to him – and Rudolf Fuka Sr. passed it on to Rudolf Fuka Jr. Today, at 83 years old, he sits before me and explains: "We're moving forward!"

He has gone through life and his professional career as an inventor – always polite and cheerful, attentive to people and their needs. The range of application problems and products he has tackled is reminiscent of Gyro Gearloose.

There are drive pulleys of all kinds and modernization kits for engine replacement. There’s a modular drive pulley for assembling different drive pulley variants and a vandal-proof call button that has been modified for this application. Remote data transmission in collaboration with Böhnke & Partner and the encoder reduction gearbox from Wachendorf, which processes mechanical conditions electronically with pinpoint accuracy. And then there's the retrofitting of dual-circuit brakes for existing systems – right down to tackling the maintenance of a wide variety of designs, not least the technology of the paternoster, the chain-circulating elevator.

Today, Birgit, Torsten and Rudolf explain to me their journey from a contract manufacturer to an internationally active elevator component manufacturer with its own production facilities. Torsten converted the sole proprietorship into a limited liability company (GmbH) in 2001. In 2004, Birgit – who had previously worked successfully in service management, though in a field unrelated to the industry – followed her brother's call back to their hometown of Cologne. Rudolf Fuka, who shaped the company for decades, remained involved.

What drives this dynamic: three people, three perspectives, one shared mindset. When asked about the FUKA DNA, all three answer without hesitation – and their answers complement each other without repeating themselves:

• "Curiosity and creativity!" – Rudolf Fuka
• "Moving forward together" – Birgit Zaunegger
• "Safety through quality" – Torsten Fuka

Three phrases that together describe a principle: We identify problems, develop solutions – and we don't do it alone.

Enablers, Not Mere Executors

Misconceptions about FUKA arise quickly: Companies that specialize in paternoster elevators and older systems are often categorized as niche service providers. That's not accurate. FUKA develops and supplies the components that elevator companies – from sole proprietors to large corporations – can use to solve problems for which there is otherwise no market solution.

Structurally, this is something different. No framework agreement with a manufacturer that primarily supplies its own service division. No high-volume business with standard parts. Instead: technical depth as a product, for anyone who needs it.

Dual-Circuit Brakes: Safety as an Engineering Challenge

Since EN 81-20 became mandatory on September 1, 2017, redundant braking systems – two independent braking units – have been required for new installations. If one fails, the other must keep the system safe. For older systems built under EN 81-1/2 or even earlier, this does not automatically apply: A single-circuit brake is a single point of failure. There is no general retrofitting requirement in Germany – but the liability risks for operators are growing.

FUKA supplies the components for this retrofit, but not as a standard product. Every existing elevator is different: space constraints in the machine room, compatibility with existing technology and certification requirements.

Paternoster: Cultural Heritage Needs Technology

Paternoster elevators are the technical curiosity of the elevator world: circulating car systems without doors, energy-efficient, space-saving and maintenance-intensive. Most are out of service or listed as historic landmarks. Almost no one wants to touch them – because spare parts are unavailable, the expertise is lacking and the business isn't profitable for large providers.

Rudolf Fuka GmbH is a sought-after source of expertise when it comes to the nitty-gritty: What needs to be tested, and how? How do you assess the operational safety and probability of failure of such systems, and what measures are appropriate? I'm looking forward to occasionally visiting a paternoster system in the Leipzig area that FB-Aufzüge, with the support of Rudolf Fuka GmbH, has comprehensively renovated and modernized.

Whether this is a passion or a business model is the wrong question. It's both – and that's exactly why it works.

Innovating Without a Patent: A Conscious Decision

FUKA's in-house developments include, among other things, vandal-proof call buttons, modular sheave components and solutions for encoder reduction gears – technology that emerged because someone identified a problem and asked: How can we solve this?

What's remarkable is that much of this was never patented. Not out of negligence, but out of conviction. Defending patents costs time, money and attention. And they restrict innovation. Instead, FUKA chose to let the industry benefit and to keep thinking ahead. That sounds like altruism, but it's also a strategy: Those who constantly optimize stay ahead – not through intellectual property rights, but through a competitive edge.

This attitude also explains why a traditional mechanical engineering company has developed solutions for electronics, control systems and safety technology – areas that don't actually belong to its own field. FUKA didn't ask whose responsibility it was. It saw the problem, sought a solution and built it.

Independence as a Principle

The elevator industry is consolidating: TK Elevator, KONE and Otis are expanding, while private-equity firms are entering the market. Family-owned companies are being acquired or pushed out. For FUKA, the situation is different – because its business model is structurally distinct from what large corporations are looking to acquire. No service network, no maintenance contracts, no end-customer business. Instead: technical expertise that is relevant to all providers in the industry.

Family Tradition and Succession

It's wonderful to see the harmony with which this family sits before me – rooted in tradition yet looking toward the future. What does "family tradition" mean in an industry increasingly shaped by corporations, private equity and consolidation?

"Let people take on responsibility! We all just want to be seen," said Torsten Fuka.

This philosophy shapes not only the leadership culture at FUKA but also succession planning. While Rudolf Fuka has two children of business-age – Birgit and Torsten – who now jointly manage the long-established company, Torsten's own children aren't quite ready yet, and Birgit's son is "still growing up."

I was impressed by how Torsten approaches succession planning through and with employees – and actively promotes it. This is not only pragmatic but also a sign of respect and foresight: A company is only sustainable if it depends not exclusively on blood ties, but on competence, passion and shared values. It's the same mindset that shapes the entire company: quality over quantity, retaining existing customers over acquiring new ones, technical solutions over marketing promises.

International Partnerships: Hyperion and the U.S. Market

FUKA is active not only in the German existing-equipment market, but also in the DACH and Benelux regions. A particularly promising development is the partnership with Hyperion Solutions in the U.S. – a company whose Titan Dual Plunger Retrofit Brake Kit 2025 was named 2025 Product of the Year by ELEVATOR WORLD.

What connects FUKA and Hyperion is more than just a shared market. Both companies are working to solve the same problem: introducing redundancy into the braking systems of existing elevators, where originally only one brake circuit was provided. The Titan kit retrofits older single-circuit braking systems and provides an emergency braking function for both geared and gearless drive-sheave machines – exactly the task to which FUKA has been dedicated for years in the European retrofit market.

The U.S. is a selective but strategically important market for FUKA – not in terms of volume, but where European engineering expertise and safety philosophy are in demand.

Conclusión

What happens to the old systems when companies like FUKA disappear? The answer is not abstract: Paternoster elevators come to a standstill. Retrofits are no longer carried out. The elevator company that needs the specialized knowledge can no longer find anyone who has it.

Rudolf Fuka GmbH is not a preservationist of the elevator world. It is a mechanical engineering firm that has precisely determined which problems it wants to solve – and that has built up the expertise to do so over generations. In an industry increasingly focused on volume, standardization and consolidation, this is not a romantic relic. It is a structural gap that someone must fill.

FUKA fills it – with curiosity, creativity and the quiet ambition to continually find the next problem for which there is still no solution. In and around Cologne, nationwide, in the DACH or BENELUX regions – or even in the U.S.!
