TECHNOLOGY REPORT | PROCESS CRANES

the coils are processed, have also received new Demag cranes. In two of the bays the process cranes are fitted with calibrated weighing equipment and highly accurate position measuring systems. As well as coil handling, these cranes will replace and position the carriers for the blanks. Sway control is important here: of the 12 cranes, six will be designed as low deadweight V-type cranes, having high load capacities and reduced oscillation characteristics. So Demag did rather more than simply supply a set of cranes. Project


management, project planning, and delivery of an integrated solution from a single source were part of the remit. The integrated solution includes the Demag Warehouse Management System, which is now responsible for controlling the entire material flow in the expanded steel service centre. In essence, therefore, Demag is embedded in the production process. Demag configures the warehouse management system for individual requirements in each application and, here, designed it to meet the specific


requirements of high-availability crane handling required for the steel industry. In the Stahlo warehouse the Demag WMS ensures (among other things) the optimal use of the available space. The direct connection to the Stahlo ERP (Enterprise Resource Planning) system creates the conditions for a continuous flow of information. Crane makers Kranbau Köthen of


Saxony-Anhalt, Germany, specialise in bespoke, process and automatic cranes. They too are just completing a very large
