Cranes and hoists

Cranes and hoists Double-girder bridge cranes by Konecranes perform crucial tasks in production In order to ensure faster and more efficient flame-cut part production, the company Jebens, a subsidiary of Dillinger Hüttenwerke AG, has installed three new double-girder overhead cranes. The equipment features of these cranes include magnetic control and magnetic hooks, as well as a crane cabin providing a better view for the crane operator. T he company Jebens GmbH is specialised in a particular technique in terms of steel production: custom-made flame-cut parts from eight to 1,200 mm thick. In addition, it is specialised in welded components, which are also manufactured for mechanical and plant engineering. Production is adjusted accordingly in a sophisticated and flexible way by the about 160 employees at the Jebens headquarters in Korntal-Münchingen, Germany. Here, more than 30 different cranes are used in the production facilities: from semi-portal to single and double-girder overhead cranes made by different manufacturers. All cranes and hoists undergo regular servicing and maintenance by the company Konecranes. For this reason, the operator has contacted Konecranes also for the planning and installation of new cranes for flame cutting machines, which are the core of production. 50 f+h Intralogistics 3/2014

Cranes and hoists “The requirements for the new cranes are high and we have accurately and jointly identified them together with Jebens. In fact, as longstanding service partners for cranes, we know the production processes in detail,” explains Dragan Maslic, Sales Engineer of industrial cranes and components at Konecranes in Stuttgart, Germany. Magnetic control and magnetic hook for all-round safety The task of these new cranes is to equip the flame cutting machines with plates and remove residual materials. To this end, they must partly transport large and heavy steel parts and store them precisely. Konecranes has therefore designed three double-girder overhead cranes with a load capacity of 24 and 40 tonnes, which precisely meet these requirements. By using the magnetic load handling device that is directly mounted onto the hook of the new crane, the steel parts can be handled efficiently. An emergency generator ensures that the loads are securely held in the event of failure of the public electricity network. One of the new overhead cranes is equipped with an ergonomically designed cabin (Image 01). In this way, thanks to the good all-round view, the crane operator Sophisticated production processes have greatly affected crane technology can, for example, unload raw materials quickly and precisely from the lorry. All cranes are controlled by radio and have infinitely variable cross travel and lifting speeds, as well as maximal lifting heights from six to 13 meters (Image 02). “Thanks to the three new double-girder overhead cranes, the transport processes for our flame-cut part production are now faster and, as a result, more efficient, thus allowing us to save time and energy. The cranes were installed in a very short time during operation,” says Jürgen Bosch, Technical Director of Jebens GmbH.
