The raw material lime is of enormous importance to the economy. It is used in various industries — for example, in iron production and in 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. 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. The railway scale is approved as non-automatic weighing instrument (NAWI).

Installation process of the weighbridge
Due to a new purchase of wagons by a customer of Kalkwerke Oetelshofen, the existing scales were 1.25 m too short for the longer wagons. 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 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 weighbridge 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.
