Underfloor railway scale with SysTec weighing electronics

Freely programmable weighing terminal fulfills customer-spectific requirements

The raw material lime is of enormous importance to the economy. Lime is used for iron production, for example, but also for the manufacture of plastics, glass, paper and pharmaceuticals.
Kalkwerke Oetelshofen GmbH & Co KG mines the raw material in the Osterholz quarry in Wuppertal-Hahnenfurth and has highly efficient lime kilns. Lump lime or limestone powder can be transported directly from the kilns to the customers via a rail network. The railway scale is approved as non-automatic weighing instrument (NAWI). W&M approved processes are essential for billing procedures. For safety reasons, it is also important that the wagons do not exceed a certain target weight. Therefore, Kalkwerke Oetelshofen have their own railway scales, which were recently replaced by SysTec partner Waagenbau Dohmen GmbH with a larger scale (15 m long) and upgraded with the SysTec IT8000E weighing terminal.
 

Key facts

• Weighing capacity: Up to 100 t, accuracy class III, W&M approved

Due to a new purchase of wagons by a customer of Kalkwerke Oetelshofen, the existing track scales were 1.25 m too short for the longer wagons of the future. Therefore, the existing weighbridge had to be replaced and the weighing pit extended. Due to the complicated installation situation under a loading system, the existing weighbridge could not be dismantled and the new weighbridge installed using cranes. The weighbridge had to be lifted using hydraulic presses and placed on cross beams. These cross beams rested on several heavy-duty rollers. With the help of these heavy-duty rollers, the weighbridges could be pulled out from under the loading station and pushed to the crane ready for loading. The crane was then able to load the old weighbridge and later lift the new weighbridge into the track bed.
