SCHWING – Concrete pump components and contract manufacturing
"voestalpine Böhler Welding is more than just a reliable supplier. We also work together with their welding experts in research and development."
The longest distribution boom of a SCHWING concrete pump, mounted on a lorry, reaches an incredible 61 metres. One can imagine the forces that it must withstand when the concrete is pumped up. This requires the greatest expertise in lightweight, high-strength steel and the production of „high-end products“. voestalpine Böhler Welding is a reliable partner.
Competence in the high-strength sector.
St. Stefan in Lavanttal is the site of the main production plant of SCHWING-Stetter, a globally leading group in the field of concrete technology and concrete construction equipment. The 500 employees in the Carinthian plant are a main reason why SCHWING-Stetter lorry-mounted concrete pumps enjoy a worldwide reputation for process safety, longevity and durability. The steelwork is manufactured from the foundation up to the boom mounting system, including hydraulic components, such as the boom’s inner, outer and extension cylinders. The company offers its expertise on the free market, particularly in the field of hydraulic cylinders where it is more than just a contract manufacturer. The range of services spans from engineering to just-in-sequence delivery.
SCHWING controls vibrations.
Important criteria for lorry-mounted concrete pumps are stability, lightweight construction and the control and containment of vibrations that occur in dynamic pumps. This is secured by good design and advanced manufacturing and welding technologies.
Supplier and research partners
Managing Director Horst Jöbstl: „We use fine grain steels with a yield strength of 700-960 MPa. For many years, voestalpine Böhler Welding has been a reliable supplier of high-strength welding consumables. However, the cooperation goes beyond that. voestalpine Böhler Welding, together with academic institutions, is also our partner in research and development. Research topics are new materials and welding consumables for high resistance to fatigue while exposed long-term to vibrations. In this way, voestalpine Böhler Welding enables SCHWING to strengthen and expand its competitive edge”.
