Efficient throughput in large format
Top quality and high-speed handling
Since March 2010, the PM2 in Eisenhüttenstadt, Germany, has been producing corrugated base paper that has a width of 10.2 m and is the highest-performing paper machine in the world. Testliner and Wellenstoff weighing between 70 and 130 g/m2 are produced on the basis of fully recycled paper. The prime objective is for the installation to reach maximum performance as quickly as possible. The reels will then be filled with 1,800 m of base paper every minute.
High performance at world-class level
Only eight months after it was first put into operation, the PM2 achieved a world record for the production of paper with a weight of 90 g/m² in continuous 24-hour operation. In April 2011, the factory set another world record: Wellenstoff paper weighing 80 g/m² continuously ran off the machine at a speed of 1,650 m/min for 30 hours.
Cranes for efficient logistics
The high production output requires reliable flow of material, which demands smooth logistics and efficient handling up to and including the shipping operation. To satisfy these requirements, Demag Cranes & Components supplied the entire crane equipment for the paper factory and the paper roll store and networked the production and logistics operations with a warehouse management system.
Demag cranes play a leading role wherever parts of the installation have to be safely transported, reels have to be picked up in cycles to match the paper machine operating cycle and rolls of paper have to be carefully stored.

Rotating spreader for heavy loads
Additional flexibility of these three crane installations is provided by two further hoist units, which enable all maintenance and repair work to be carried out. Two DR-Pro rope hoists travel along the crane girders of each crane in the form of cantilever crabs. Thanks to their compact design and fast lifting speeds, they are used for installing and removing machine parts that weigh up to 10 tonnes.
