Tower Cranes vs Mobile Cranes Article





Der Leitwolf. Leader of the Pack.

From humble beginnings as an iron foundry in 1854, the pioneers at WOLFFKRAN introduced the first tower crane ever in 1913. Since then, over 100 years later, WOLFFKRAN is still the “Leader of the Pack” in technology and quality for tower cranes worldwide.

WOLFF tower cranes have been seen on some of the largest jobsites in the world from Berlin to Dubai, from the Wembley Stadium in London to the Vienna Airport, as well as here at home, at the reconstruction of our own World Trade Center in New York City.

With engineering that is second to none, WOLFF tower cranes get the call of duty whenever difficult projects have to be mastered. For these reasons, we at Custom Service Crane, Inc. have elected to put our trust in WOLFF tower cranes for all of our heavy lift machines.

Our Wolffkran tower cranes have already been contracted for demanding jobs, such as the extensive “East End Transformation” at Washington University in St. Louis where three of our towers are located. Click below for photos or to view live webcam footage on the Washington University website.
