Following the rebranding of Wolffkran Norge AS as a subsidiary of Wolffkran Holding AG, the company is now heavily involved in two major construction projects in Oslo. Five WOLFF 7534.16 Clear cranes are playing a critical role in the redevelopment of Oslo’s Ulven district, a former industrial area, in partnership with Norway’s largest construction firm, Veidekke.
Two WOLFF cranes have been integral in constructing the “Ulvenkroken” residential complex, a 180-unit building. Each crane, with a lifting capacity of 16.5 tons and a jib radius of 60 meters, was used to transport heavy prefab components and to pour elevator shafts continuously using slipform technology, achieving an impressive lifting speed of 185 meters per minute.
The project leveraged WOLFF’s two-part foundation anchor system, a sustainable solution allowing the reuse of high-quality parts. Operational challenges, including the proximity of nearby cranes and coordination with adjacent railways and roads, were managed effectively through synchronized anti-collision systems.
In a parallel project, three WOLFF cranes are constructing Veidekke’s new headquarters, a sustainable building located near Ulvenkroken, which received a visit from Crown Prince Haakon during construction. The Oslo projects mark the first collaboration between Veidekke and Wolffkran Norge AS. “Wolffkran supported us through every phase, from planning to night operations,” notes Morten Opstad Aarseth, Veidekke’s Project Manager, calling it a “successful debut.”
