Success Story with Hoesch Hohenlimburg GmbH

Three-Dimensional Store Visualization and Identification of Steel Slabs - Exact to the Inch

Inventory management system of Hoesch Hohenlimburg
Moved objects: steel slabs
Crane system with LPR® sensors

The challenge:
Headquartered in Hagen, Westphalia, Hoesch Hohenlimburg GmbH specializes in hot-rolled steel strip. Here, “Hohenlimburg medium strip” is manufactured from slabs by hot rolling in widths up to 685 mm and thicknesses of 1.5 to 16 mm. The heavy steel slabs delivered to Hagen are stored temporarily side by side and on top of each other and all need to be identified without error in order to avoid confusion when picking them up with a crane, for example.

The solution: A state-of-the-art inventory management system has the function of identifying the slabs individually on delivery, of assigning optimal store positions and of coordinating the subsequent processing sequence efficiently. To effect this, LPR® units mounted on the crane trolleys record every single movement of the trolleys and so enable consistent identification of all moved objects in store. The movement profiles are then combined with data obtained by laser surface scanning the slab piles and with existing information taken from a data base system.

The project´s success: The inventory management system now has position data of every single stored object down to an accuracy of ±50 mm available. This allows three-dimensional store visualisation that can be used for coordination of logistics as well as for intuitive instructions for the crane operator generated by the system. There is virtually no risk of confusing slabs anymore and at the same time, the store turnover was increased by 20 percent.
