Wheat flour, starch, and wheat gluten for the worldwide food industry are produced by Jäckering Mühlen und Nährmittelwerke GmbH in the North Rhine-Westphalian city of Hamm. To do this Jäckering procures grain from within an 500 kilometer radius. Bulk good freighters deliver the grain daily at Hamm harbor, where it is milled and further processed. Jäckering has relied on a materials handling machine from SENNEBOGEN since 2009 for unloading and charging the hopper attached on the harbor building.

The challenge associated with the logistics concept was the depth of the harbor basin in conjunction with the higher positioned silo hopper. In close collaboration with the local Sales and Service Partner, BRR Baumaschinen Rhein-Ruhr GmbH, it was possible to configure the SENNEBOGEN 840 as the optimal machine, and it has now completely replaced the three former harbor rail cranes. In order to achieve an appropriate reaching depth in the hull, and simultaneously cover the height of the silo hopper, the machine was elevated by 2.7 m with a mast. The 840 M special is powered by a powerful 194 kW diesel engine and it has a 20 m equipment length with special materials handling kinematics. The all-wheel drive of the wide-gauge undercarriage also ensures flexible implementation of the materials handling machine along the harbor basin.

Equipped with a 3.5 m³ double shell grab, operator Suleyman Durmus handles up to 400 tons an hour – just under 30 seconds are required for a cycle. Thus the machine already delivers more than the existing hopper can process. From the hopper the grain ultimately goes into the modern milling plants. Approximately 240,000 tons are processed each year, the majority of which ends up as starch or wheat gluten in world trade.

For the operator, the 2.6 m maXcab, which can move forward, and be elevated by 3.0 m, offers the highest level of operating comfort. Together with the armored class floor window and an extensive lighting package the operator always has an unrestricted view of the work area, which is very effectively illuminated. Additional railings all around the upper carriage guarantee safe work and easy access for maintenance and service.
