High-flying screen

Back in December 2010, Metso’s exclusive distributor for Switzerland, Drossard Sales & Service GmbH, caused quite a stir when the LT96 jaw crusher really took off. Contracted by Martitechnik AG, the Metso distributor transported the LT96 by cableway to its assigned operating site at an altitude of 2474 m in the Swiss Alps. In September 2011, the distributor was able to repeat this extraordinary action in Switzerland, this time taking Metso’s ST3.5 mobile screen to a height of just under 1857 m (Fig. 1). The realization of this project was preceded by meticulous planning – especially as two cableways with different capacity requirements were involved in the transport of the machine. Besides the necessary technical data such as the load centre of gravity, stability aspects and dimensions, it was important to take into consideration the weather and the necessary light as the cableway only transports loads in daylight. The new ST3.5 screen is supporting the “Linthal 2015” project. The mobile Lokotrack is involved in the expansion of the Linth-Limmern power plants, where it is helping with the preparation of the terrain for the major construction site and for the processing of aggregate (Fig. 2). This unique power plant project – a joint venture between the Swiss Canton of Glarus and Axpo AG – is aimed at increasing power generation at the Linth-Limmern hydropower plant (KKL), thus assuring the future power supply for North-Eastern and Central Switzerland. The project is to be completed within five years and will employ a total of 250 ­people. The total costs of the project amount to around 2.1 bill. Swiss francs. The new ST3.5 mobile screen, which Drossard Sales & Service GmbH transported by cableway, is also the first one in Switzerland. Not only the type name ST3.5 (3 stands for the number of products/double-deck screen; 5 for the screen width – corresponding to around 1500 mm)...
