Joint managing director Marcus Wittrock said: “We have been running this type of crane since 2003 and our customers expects us to offer the full product range."
Fellow MD Oliver Herrmann added: "The market for MK cranes has developed quite positively for us in recent years. In the meantime, these are increasingly sought after machines, which is why we are not only replacing, but also expanding the fleet."
The group includes Herrmann & Wittrock, Ulferts, Titschkus & Wittrock, and Ulferts & Wittrock - can trace its origins back to 1909 when Hermann Titschkus established a haulage company. Crane rental began in 1970 with Mennen & Wittrock, followed by the founding of Ulferts in 1972 and Ulferts & Wittrock in 1989. Over the years, the group has expanded through startups and takeovers.
The companies run a fleet of 200 mobile cranes up to 700 tonnes and crawlers up to 650 tonnes as well as forklifts and aerial work platforms.
