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.
