Water Management

The “Iron Gate”, on the Danube River in the southern Carpathian Mountains on the border from Romania to Serbia, is regarded as one of the most impressive gorges in Europe. Two river power stations built in 1972 – “Iron Gate” 1 and 2 – with a lockage had tamed what had been up until then the most dangerous section of the Danube River for navigation. For the maintenance of this lockage, Columbus McKinnon Engineered Products GmbH, Kissing/Germany, has now designed and installed a special lifting device. The linear lifting solution consists of four high-precision and proven heavy-duty screw jack elements SHE 100.1 made by Pfaff-silberblau. These lift and lower the heavy lock gate weighing some 200 t by 700 mm – with a deviation of less than 0.1 mm.

Summer 2015 will see the inauguration of the region’s first flood barrier in Greifswald on the German Baltic Sea coast. Columbus McKinnon Engineered Products, Kissing/Germany, is deploying its SHE worm gear screw jacks of the Pfaff-silberblau brand to move the sliding gates of the harbour pier into place to protect against flood waters.

Thanks to their robust design, the successful SHE screw jack elements from Pfaff-silberblau are perfectly equipped for use in difficult environmental conditions. Designed specifically for use in the extremely aggressive conditions of the paper industry, the company Columbus McKinnon Engineered Products GmbH (Kissing/Germany) has now extended its versatile SHE range with the option “stainless”. The newly developed SSP series from Pfaff-silberblau with integrally cast swivel brackets is easy to clean and satisfies with ease the exacting requirements with regard to corrosion protection in the paper making and processing industry.
