Worldwide production of hybrid towers for wind turbines in German factory quality
Mobile factory from Max Bögl wins bauma Innovation Award
The success story continues: The mobile factory from Max Bögl Wind AG has won this year's bauma Innovation Award in the category Construction Method. The manufacturing concept for wind turbines, which is unique worldwide, convinced the jury as a technical and innovative product as well as for its contribution to climate protection and resource efficiency. The mobile factory has already been described in detail in an article in CPI 2/2019.
The bauma Innovation Award has been presented in five categories every three years since 2007 on the occasion of the world-leading trade fair of the same name for construction machines, building material machines, mining machines and construction vehicles and devices. This year Max Bögl Wind AG convinced the jury, which was made up of representatives from science and industry, with the unique concept of the mobile factory. The Bavarian company is the market leader in the manufacture, delivery and erection of hybrid towers. With the award-winning mobile production concept, the manufacture of hybrid wind turbine towers – a combination of concrete elements and steel segments – is possible in German factory quality virtually anywhere in the world. The evaluation criteria in the Construction Method category, which are referred to for the award under the leadership of the German Machine and Plant Construction Association (VDMA), include level of innovation, contribution to resource efficiency and implementation requirements.
Optimised process sequences worldwide
The hybrid towers are manufactured at Max Bögl in two stationary plants in series production. In order to make the manufacturing of the tower system cost-effective and efficient in international projects too, the series production concept was transferred to a mobile concept. "The change from the classic individual construction to building-related series production is an important building block for our company so that we can implement projects even more quickly, flexibly and cost-effectively. Internationally too, we are falling back here on already established manufacturing processes at our parent plants", explains Stefan Bögl, CEO of the Max Bögl Group. As a trained mechanical engineer, he incorporated the series production concept into both the company and the development of the mobile factory from the very start. "The standardised processes allow us to quickly train the local workforce on assignments in the most diverse regions and at the same time to guarantee high process reliability." It was possible to adapt the entire equipment for the mobile manufacturing concept – for instance the CNC concrete grinding system. It ensures that the concrete segments of the hybrid tower are ground in the same quality as with stationary plants. The concrete tower can thus also be erected internationally under any weather conditions. With a production duration of approx. two days per tower, the mobile factory operates very quickly and efficiently.
Award is a success for all employees
Stefan Bögl is delighted by the award: "From the idea to the implementation and now this award: the entire Max Bögl team has contributed to this success with great dedication and know-how. Only those who think courageously and take on challenges can implement innovative projects and make a difference sustainably." Josef Knitl, Chairman of Max Bögl Wind AG, underlines the success of the mobile factory: "Sustainability and climate protection start with the production of renewable energy sources. With the first successful project in Thailand we have proven that we can manufacture resource-saving hybrid towers in German factory quality anywhere in the world. Such projects will be crucial in future so that the energy change can be successful worldwide."
Successful first use in the Far East
The tallest wind turbines in Southeast Asia were built with the mobile factory at the beginning of this year. It proved to be the case here that the manufacturing concept satisfies all demands of German factory quality on the one hand and increases the local added value on the other. Max Bögl Wind AG erected a total of 90 hybrid towers for the Thepharak wind farm, each with a hub height of 156.5 metres. In doing so the company mainly used local materials and manpower. This increased the cost-effectiveness of the project, relieved the infrastructure and environment and is good for the region overall.
