Mechanical engineering company Kurtz Ersa required a new crane to lift larger and heavier components into a new milling machine. It needed to lift 16 instead of the previous 5 tonnes and to travel on the existing crane runway. The lifting height and restricted clearance above the crane bridge also played a part. Stahl- und Kranbau Oeder, one of STAHL CraneSystems\u2019 partners, developed a customised low-headroom crane with an unusual design.<\/p>\n

Kurtz Ersa produces particle foam and casting machinery at its plant in Kreuzwertheim. The powerful machines are used all around the world \u2013 from low-pressure casting of engine blocks to pre-expanding and shape-moulding helmets and shoe soles. Kurtz Ersa relies on 235 years\u2019 experience, well-trained personnel and ultramodern machinery to produce these high-precision machines. At the beginning of August 2015, Kurtz Ersa commissioned a new travelling column milling machine that works to 0.017 mm accuracy over 10 m and with which larger and heavier components can now be processed. However neither the existing crane nor the crane runway were designed for the required lifting capacity of 16 tonnes. Designing a new 16 t crane for the existing crane runway proved to be more difficult than expected and posed insoluble problems for some crane builders.<\/p>\n

On the one hand, the limited clearance between crane runway and ceiling played a role, on the other the specifications for the lower edge of the load hook which could not collide with the milling machine\u2019s spindle motor. Specialist for customised cranes, Stahl- und Kranbau Oeder from Eckental in Franconia, South Germany, found the optimum solution: \u201cThe crucial point of the system was definitely the restricted installation situation and the existing crane runway which we could not reinforce,\u201d Rudolf Lang remembers, an engineer from Stahl- und Kranbau Oeder, one of STAHL CraneSystems\u2019 certified partners. Oeder supplied a customised crane with a headroom of only 943 mm from the upper edge of the wire rope hoist to the lower edge of the hook, that utilises the lifting height up to 236 mm below the crane runway and still manages with the restricted space above the crane runway.<\/p>\n

\u201cThe starting point was a standard CraneKit from STAHL CraneSystems with two 8 t wire rope hoists from the compact SH series \u2013 together with our motto: When space is tight, we\u2019re the people you need,\u201d Rudolf Lang says. His solution is based on a number of off-standard designs that would not be possible with a standard crane. \u201cWe had to devise a special construction for the crane bridge,\u201d Rudolf Lang explains. \u201cOn this crane, two SH wire rope hoists with modified crabs travel on rails mounted inside the bridge girders. Only this feature together with altering the distance between the bogie endcarriages made it possible to build such a compact crane.\u201d The load is distributed onto coupled crane endcarriages with a total of 8 wheels so that the maximum load capacity of the crane runway is not exceeded. The load actually suspended from the hooks appears on the display of the radio remote control.<\/p>\n

The crane is also equipped with the safety features necessary for tandem operation. This can be activated via the remote control and enables lifting heavy and long workpieces safely. Norbert Jonas too, Kurtz Ersa\u2019s production manager, is more than satisfied with the new crane. \u201cYou need creative engineers like Rudolf Lang and his colleagues to design a crane with these specifications \u2013 a remarkable achievement and a technically convincing crane. We\u2019ll certainly get in touch with Stahl- und Kranbau Oeder for future projects.\u201d<\/p>\n
