Process cranes for Chinese paper factory

Demag Cranes has received an order for eight fully automated process cranes and a warehouse management system from Chinese company Anhui Shanying Paper Industry Co. Ltd. The cranes will be used in what will become the largest paper-roll shipping store in the world, Demag said, constructed at Shanying Paper’s headquarters in Maanshan, China.

The rolls produced by two new paper machines will be stored temporarily and prepared for shipping. The cranes are equipped with mechanical roll clamps, which can hold up to four rolls at a time. Commissioning of the store is planned for the end of 2012.

Like the production facilities, the cranes will be in operation 24/7. In each of the four bays, two cranes with load capacities of 4 tonnes and a span of 35m will travel on 162-metre-long crane runways. The cranes will take the packed rolls and stack them in a tower-like fashion up to a height of 14.3m. The long and cross-travel drives have infinitely variable speed control and reach maximum speeds of 120 and 100m/min respectively; depending on the load, lifting motions are controlled at speeds of up to 81m/min.

Lu Zhao Jin, vice general manager of Shanying Paper said: “The investment in a new paper-roll shipping store forms an essential component of our rigorous growth strategy. With Demag Cranes we are focusing on a reliable partner with first-class references for this large-scale project.”

Dr. Lars Brzoska, executive vice president of industrial cranes at Demag, responded: “The paper-roll shipping store operated by Shanying Paper represents a further milestone in terms of storage capacity and handling volume. With the automated stores we have used to date, we have provided our customers with considerable support in increasing handling rates over the entire process chain of paper production. In this way, we have also developed a very good position for ourselves in the growth market of the Chinese paper industry.”

Shanying Paper, based in Maanshan in the province of Anhui, is considerably expanding its capacity for paper for corrugated cardboard tubes. In the second half of 2013 the company will be commissioning two new paper machines with capacities of 1,540 tonnes of corrugated medium and test liner paper and 1,380 tonnes of test liner paper and Kraft liner paper in daily operation.
