Expanding the machining capacity in Denmark

With substantial growth in our customer base in Denmark, Manufacturing Solutions has invested strongly in a new infrastructure and in new tools and machines in order to meet the demand from our customers.

Recently, a new and much larger plasma cutting machine has been added to our production assets.

At AH Industries, we are constantly looking for new ways to strengthen our competitive power, because that’s the only way we can keep our customers competitive, too. This sometimes means looking at better and more efficient ways of producing components.

As an example, in early 2016, our Danish cutting center was moved from Rødekro in Southern Jutland to the Ribe facility, a move that eliminated in one stroke much of the transport required to move components around. At the same time, we began looking at new investment possibilities to expand our capacity, and the first result is now in: Our brand new Zinser plasma cutter.

At 400 amps, the new cutter is more powerful than the one we have previously used. Among other things, this means that Manufacturing Solutions in Ribe now has the capacity to plasma-cut steel sheets up to 80 mm in thickness and with beveling up to 50 mm. Previously, such work had to be done manually with a torch or by the process of milling.


Much larger components with higher precision

The new plasma cutter allows us to handle steel sheets with sizes up to 3,000 mm X 12,000 mm. In beveling operations, the width of the component cannot exceed 2500 mm, but this should be more than sufficient for most applications. A series of exhaustive tests have shown that the cutter is just as precise as when using a traditional torch cutter – even when it comes to the notoriously difficult 90 degree cuts.

“We are located in the West of Denmark, near the North Sea and the offshore oil industry, and a lot of our customers serve this segment,” says business unit director Jeppe Lund from AH Industries’ Manufacturing Solutions. “Our customers in this industry, as well as in the shipyards, the wind business and other heavy industries, all have expressed a desire for us to expand our capacity in plasma cutting, and this latest investment is our reaction to this.”

Substantial customer growth

In fact, new plasma cutters and other investments are a natural result of substantial growth in new customers in the past year and a half. ”Our customer base has grown by 20 % in a very short time, and we expect further growth of app. 15 % in the coming year,” says Jeppe Lund. “Investing in machinery and in our own infrastructure means that we will be able to retain customers all across the country and beyond.”

New deliveries to the cement industry

AH Industries Industrial Solutions has recently completed the delivery of two large strike bars and eight apron feeders for cement crushers from our production facilities in Denmark and in Ningbo, China.

Strike bars and apron feeders are core components in material handling in the cement and mineral industry and must be able to withstand enormous forces – and to remain in operation for months and years on end without problems. This is why many global operators in the cement and mining industry turn to us for the manufacture and servicing of these crucial parts.


In recent months, we have completed the production and delivery of eight apron feeders and two large strike bar crushers for the cement industry in the Far East. Thomas Hamborg-Thomsen, business unit director for Industrial Solutions, says, ”we have enjoyed a long-lasting collaboration with major players in the cement industry for decades now, and this latest delivery shows the strength of these relations.

These components are critical to the running of cement plants, and they are real heavy-weights; in order to live up to our customers’ expectations, we need to have a strong global setup of suppliers along with our logistics and quality assurance setup – and we do.”

Anchor cages for wind turbines: A new ready-made solution from AH Industries

Over the years, AH Industries has delivered an increasing number of foundation solutions for major WTG producers in the Asian market.

Now, we are extending our customer base to include installations in Europe and in North America – and our solutions include both anchor cage parts and cages shipped in sections.

The global wind industry is one of the main markets for AH Industries and our three business units: Site Solutions, Manufacturing and Industrial Solutions. “This setup with three independent business units gives us a very strong position in the manufacture and servicing of wind turbine components worldwide,” says Thomas O. Kristensen, Head of Business Development at AH Industries.


“We have our Site Solutions to provide lifting equipment for erection of new turbines and servicing of turbines in operation, we have our Manufacturing Solutions unit which handles serial production of components for new unit wind turbines, and our Industrial Solutions business unit can take care of project production orders, service and prototyping. This is quite unique in the world of machining, and it allows us to develop and offer total solutions for all players in the wind industry.”

One example of this is our production of anchor cages as container-shipped kits.


Keeping wind turbines upright

Anchor cages are critical components in most on-shore wind installations. They form the reinforcement core of the turbine’s foundation and must be able to withstand and distribute into the foundation all dynamic and static forces developed once the turbine is installed and is in operation.

Quite substantial forces, too, as modern wind turbines of 2 or 3 MW can reach hub heights of more than 100 meters and have rotors with diameters exceeding 120 meters. At the foundation, the largest towers are more than 5 meters in diameter and are mounted on the foundation by 200 bolts or even more; bolts which are part of the anchor cage itself.

AH Industries now offer wind turbine producers and contractors the possibility of getting anchor cages as a ready-made kit solution including bolts, anchor ring and flanges– delivered on-site in containers or shipped as a just-in-time solution.

Segmented rings with proven strength

In the US, contractors have a tradition of installing anchor cages as complete units. But with wind turbines growing ever bigger, the challenges of logistics and transport grow with them. Hauling an anchor ring with a diameter of 5 meters or more is neither very practical or very economic.

At AH Industries, we have begun offering our anchor cages as segmented rings instead – we deliver the foundation rings in e.g. five segments of 72 degrees of circle each. And there are no worries over strength – in fact, segmented rings are just as strong as complete rings, once they are installed in the turbine foundation.

EN 1090-1 in place

As the anchor cages form part of the combined structure of the wind turbine, the production of the cages must comply with the EN 1090-1 standard for structural steel construction. AH Industries has this certification in place – as Thomas O. Kristensen explains: “With this certification in place, and a strong product on offer, we can give contractors and OEMs a solution which is superior in terms of logistics and installation time. In the US, we are up against traditional ways of doing things, but we can show clearly that our solution is far more competitive and just as good in terms of structural strength.”

Right now, AH Industries is receiving several orders for anchor cages with more on the way.

Cement factories and wind retrofit: New Industrial Solutions products

As a major supplier of large components to the international cement industry, Industrial Solutions handles the sourcing, machining, assembly and logistics involved in large-scale projects all over the world. Now, three new component types and one complete wind turbine concept are added to the product portfolio.

Industrial Solutions is an independent business unit with AH Industries. Recently we added three new product types to our range of components for the cement industry: Apron feeders for the transportation of rocks within the cement factory, strike bar crushers, for crushing of raw material and hydraulic trust devices, which act as a safety feature.


The new components are sourced and assembled by AH Industries at our facilities in both Denmark and in Ningbo, China, and delivered on-site ready for assembly. Initially, the new components are intended for cement factory installations in Pakistan, Vietnam and Algeria, but more facilities are sure to follow.


Close to the customers

Thomas Hamborg-Thomsen, director of the Industrial Solutions business unit within AH Industries, explains: “We are able to win these large commissions because we always maintain a close dialogue with our customers.

We have worked closely with their value engineers to discover how best to increase value across the supply chain, and we know their needs – not just in terms of components but also in terms of assembly, logistics and so on. Combined with our long track record in the cement industry, we believe this is what gives us the competitive edge in a tough market.”

Complete drive train solutions for the wind industry

Industrial Solutions is also adding a new concept for the wind industry to its portfolio of services.

“One of our latest product additions is a complete concept for drive train retrofit in wind turbines,” Thomas Hamborg-Thomsen says. “When performing a refurbishment of a wind turbine, it is often necessary to replace the whole drive train – the main shaft, main bearings and so on.

We can deliver all of this as a complete kit, ready to install either with new or retrofitted components per customer demand. And we can call on our colleagues in Site Solutions to deliver the hardware needed for installation of the drive train, too.”

Site Solutions is the special branch of AH Industries which specializes entirely in the development, production and servicing of dedicated equipment for the handling and installation of wind turbines.

“What this shows is that AH Industries is more than just a supplier of components – in fact, we can take care of the entire value chain for our customers – and that’s a huge benefit, because our customers only need one point of contact in order to get everything done” says Thomas Hamborg-Thomsen.

Wind tower foundations ready to install from AH Industries

With the world’s wind industry booming, new and better logistics solutions are needed to guarantee fast on-site installation of vital components.

Over the years AH Industries has developed a smart way of producing, packaging and delivering steel parts for tower foundations directly on site – as a readymade, timesaving kit.

When constructing foundations for wind turbines, huge forces need to be tamed. A modern wind turbine sweeps an area many times the size of a football field, and all the forces from the wind that are absorbed through the nacelle, tower and finally the foundation are quite impressive.

These forces need to be directed into the ground and to absorb the different types of loads inherent in the entire system – and this requires a very unique design. Contractors build big concrete foundations with anchor rings and bolts that are both strong and flexible, so that the tower can operate without suffering damage.


AH Industries has delivered systems of anchor rings and foundation bolts for very large wind turbines for many years. The manufacturing of the components usually takes place at the AH Industries facilities in Ningbo, China, from which the Australian and US markets are served, or from Ribe, Denmark, from which the adjacent markets are served.

As a unique feature the entire tower foundation can be delivered ready to install directly on site – in much the same way as you get a piece of furniture flat-packed and ready to assemble at home.

“We have decades of experience of manufacturing foundation components for wind turbines, and for delivering comparable large foundation components to the cement industry,” says Knud Andersen, CEO of AH Industries. “But with the projected growth in wind installations world-wide and the ever-increasing size of these projects, contractors need a fast and safe way of constructing foundations on-site without too many man-hours involved.

We have that solution ready for them. We can deliver just the right amount of parts on site packed for easy access and at the precise moment when the parts are needed. This makes a huge difference, because contractors can be sure to stick to their plans and to deliver the project to the end customers on time, as agreed.”

On-time delivery anywhere in the world

The steel parts of a tower foundation normally consist of a set of circular flanges that are held together by meter-long, extremely strong and flexible foundation bolts. The concrete is cast and the tower mounted on the foundation.

The steel allows the tower to flex with the wind – too stiff a construction, and the foundation will crack or the tower collapse. Therefore, real steel experience is needed when manufacturing such components.


But equally important is the logistics involved. Knud Andersen explains: “It’s a question of just-in-time delivery on site. This is absolutely crucial, because an installation team with nothing to do just costs a fortune for the contractor.

Therefore all components must arrive precisely on time and ready to be installed. We can deliver that through our dedicated logistics setup and in-house key production processes, no matter where the installation takes place.”
