Tadano Demag

Tadano Demag GmbH is a German manufacturer of mobile cranes based in Zweibrücken, Rhineland-Palatinate, and part of the Japanese Tadano Group. Its production heritage reaches back to a mechanical workshop established in Zweibrücken by Christian Dingler in 1827. Over nearly two centuries, the site evolved from manufacturing presses, steam engines, foundry equipment and industrial machinery into a major European center for heavy mobile-crane engineering. The facility became associated with Demag during the postwar consolidation of Germany’s machinery industry. Demag acquired a stake in Dinglerwerke in 1954 and subsequently brought the business fully into its construction-machinery organization. During a reorganization of the group’s construction-equipment operations, mobile-crane activities were concentrated in Zweibrücken in the early 1980s. The site later became known for large telescopic all-terrain cranes and lattice-boom crawler cranes, including the very-high-capacity Demag CC 12600 crawler crane introduced in 1998. After the restructuring and breakup of Mannesmann’s industrial businesses, the mobile-crane activities were separated into Demag Mobile Cranes GmbH in 2001. Terex acquired the Zweibrücken plant in 2002 and integrated it into Terex Cranes. For a period, cranes were marketed under the Terex-Demag name and then primarily under Terex. The Demag name was restored to the crane business in 2016, reflecting the commercial value of the established German engineering identity. Tadano acquired the business in 2019 and initially operated it as Tadano Demag GmbH. In 2020, Tadano Europe Holdings GmbH was established in Zweibrücken as the holding company for the group’s European activities, alongside Tadano Demag GmbH and Tadano Faun GmbH as operating production companies. Tadano Demag entered protective shield restructuring proceedings in 2020 and completed insolvency proceedings on 1 April 2021. The reorganization strengthened coordination between the Zweibrücken plant and Tadano Faun’s facility in Lauf an der Pegnitz, including the movement of vehicle-carrier chassis from Lauf to Zweibrücken for final crane assembly. Although the Tadano Demag corporate name remained in use, Tadano discontinued the Demag product branding after the acquisition. By autumn 2021, models were being presented under the Tadano name. The Zweibrücken operation nevertheless remains an important Tadano engineering and manufacturing base for large mobile cranes. Its range includes multi-axle all-terrain cranes with telescopic booms and modular lattice-boom crawler cranes, with lifting capacities reaching up to approximately 1,600 tonnes for the company’s broader product scope. The company serves construction contractors, crane rental firms, infrastructure developers, industrial projects, energy businesses, petrochemical facilities and other customers requiring high-capacity lifting. In 2023, the Zweibrücken operation employed approximately 1,100 people. In 2024, management announced restructuring measures involving workforce reductions and the closure and sale of the Wallerscheid site, while retaining and modernizing the main Dinglerstraße plant. The agreed measures included a reduction of 249 positions, investment in the principal site, modernization of production, painting and training facilities, and the creation of additional areas for large-crane inspection and repair.

The industrial history of the Zweibrücken site begins in 1827, when Christian Dingler opened a mechanical workshop employing ten people. The business initially produced oil and cutting mills and later expanded into printing presses. Dingler’s toggle press became widely known as the Dingler press and helped establish the company’s reputation beyond the local market. After acquiring the Schönhof estate in 1834, Dingler created a larger machine factory. An iron and metal foundry, steam-powered equipment and eventually steam engines were added during the nineteenth century. The company expanded into heavy industrial machinery under the Dinglerwerke name. It produced water wheels, turbines, hoisting and conveying equipment for mines and steelworks, and other machinery. In 1897 it became a joint-stock company. Its first rail-mounted crane was built in 1906, and by the 1930s its product range also included cranes, rollers, asphalt-paving machinery and concrete-paving equipment. During the Second World War, parts of the business were relocated and used for military-related production, including submarine components. The company also participated in the construction of a large wind tunnel project in the Ötztal region. Demag acquired a stake in Dinglerwerke in 1954 and eventually took full ownership. The Zweibrücken operation was incorporated into Demag’s construction-machinery division. In the 1970s and early 1980s, ownership passed through the Mannesmann group, and the mobile-crane activities were concentrated in Zweibrücken during a construction-machinery reorganization. Mannesmann acquired Demag completely in 1983. The site then developed a strong position in large mobile and crawler cranes. A notable engineering milestone was the 1998 launch of the CC 12600 lattice-boom crawler crane, rated at 1,750 tonnes and equipped with advanced boom, drive, Superlift and Ringlift configurations. Following the breakup of Mannesmann’s industrial businesses after Vodafone’s takeover, the mobile-crane operation was separated as Demag Mobile Cranes GmbH in 2001. Terex acquired the Zweibrücken plant in 2002 and incorporated it into Terex Cranes. The cranes were initially associated with the Terex-Demag name, but the branding was subsequently shortened to Terex. A subsidiary site at Bierbach, originally established in 1925, was reactivated in 2006 and later closed and sold in 2017. The Demag brand was revived in 2016. Tadano acquired the business in 2019 and retained the Tadano Demag corporate designation. In 2020, Tadano formed Tadano Europe Holdings GmbH to coordinate European operations. Tadano Demag entered protective shield proceedings in 2020 and completed the insolvency process in April 2021. The restructuring increased operational coordination with Tadano Faun in Lauf an der Pegnitz. Chassis produced at Lauf were sent to Zweibrücken for final assembly and delivery. The Demag product name was phased out after the acquisition. By autumn 2021, crane models carried the Tadano name, aligning the German operation with Tadano’s global brand architecture. The Zweibrücken plant continues to develop and manufacture large all-terrain and crawler cranes. Its modern product examples include the five-axle AC 5.250-2 and extended-boom AC 5.250L-2 all-terrain cranes, as well as the 1,250-tonne-class CC 78.1250-1 crawler crane. In 2024, Tadano Demag announced a restructuring involving the Wallerscheid site and the Zweibrücken workforce. The agreed plan reduced the number of affected positions to 249, kept the main Dinglerstraße plant operating and included investments in production, painting, training, inspection and repair capabilities. In 2025, Noriaki Yashiro was appointed chairman and chief executive officer.
