The commission

Fitting the paper rolls to the production machines called for a crane with two synchronised hoisting units with a lifting capacity of five tonnes each for smooth and even lifting and lowering operations. The crane installation was also to be designed for full access to all points.

Contract scope

The difficult installation environment ruled out using a standard crane unit. The crane location was on the first floor of the building and the new crane could only be installed via an opening in the floor. Each of the main crane components therefore had to be designed with this in mind.
The limited space presented a real challenge in terms of workplace accessibility and component dimensions. Blumenbecker Krananlagen Hamm therefore designed and built a special crane bridge to overcome these problems.
After undergoing trials in Hamm the crane was disassembled into its individual components, painted and shipped to Bielefeld. The old crane unit was dismantled, and its replacement installed, during a four-day production stoppage in October 2013.
