Maximizing the productivity
A parent roll handling crane, also known as a dry end crane or winder crane, lifts the rolls of paper produced in a paper mill from the winding station. First, the paper needs to be dried, then passed through calenders to form its thickness, after which it is put on a storage rack, or placed on a transfer car for delivery to another part of the plant for coating or cutting. The empty spool shafts go back to the paper machine winder’s storage rails. Typically, there are one or two roll changes per hour.
A Konecranes parent roll handling crane is dimensioned for handling all process machine output in a standard paper mill. It is designed for accurate movements, needed when lifting heavy rolls around high-speed machines. Made for safety and durability, its electrics are protected from the potentially corrosive, warm and wet environment in which it operates. Larger roll cranes can have multiple purposes across plant processes, including maintenance.
Customer story - Oji Paper, China
" Safety and ease of operation are emphasized in every Konecranes product and service. Konecranes process automation is very advanced. We could even design safety areas in factory before hand. We were also impressed about the safety features of the crane. Cranes play a crucial part in paper production process. A non operation crane will stop the production. We see Konecranes as a strong partner. Not only as a supplier of crane but a long term partner"
