 RUBBLE MASTER Conquers Swiss Mountains
RUBBLE MASTER RM100 in action at largest Swiss energy project Linthal 2015
When engineers manage to move a 28 ton "lightweight" RUBBLE MASTER RM100 from the valley from 817 m to 2150 m above sea level using a material cableway, it has all the makings of a "heavyweight" contest. And this was precisely the case some months ago, high up in the Swiss mountains for the expansion of the Linthal power station (Linthal 2015) in the Swiss canton of Glarus.
The best choice for extreme jobs
"The deciding factor in favour of the RUBBLE MASTER RM100 was without doubt the fast availability from the local dealer Biedermann-Unterhalt- & Vertriebs GmbH (BUV). The combination of the low weight and the compact design which made it possible to take the crusher up the mountain with our material cableway in one go without any additional work was another deciding factor," explains Jonas Wyrsch, project manager for Linghal 2015. "The crusher fulfils our requirements in every respect! In addition to this, the instructions on how to handle the machine were very professional, BUV really looked after us," says the project manager.
 "Light enough to take a trip with the cableway"
The recycled material is being used to make ski slopes and as ballast material to begin with. All in all around 25 000 t of rock will be processed in the first phase. The versatile RUBBLE MASTER RM100 produces up to 145 t of 0/40 mm cubic aggregate per hour. The feed material is limestone rock measuring up to 850 mm which has been blasted from the mountain. "Being involved in this prestigious project confirms once again the many areas of use and value retention of the RUBBLE MASTER crushers," says a delighted Gerald Hanisch, RUBBLE MASTER founder and CEO. "The RUBBLE MASTER RM100 is even light and compact enough to take a trip with the cableway," says Hanisch, with a smile on his face.
Extreme conditions
"The Limmern power station consortium faces some particularly tough challenges in this construction project," says Jonas Wyrsch. "The job sites are up to 2474 m above sea level, in winter there can be metres of snow and the low temperatures stretch both man and machine to the limit."
Once this project is finished another high-climbing challenge awaits the RUBBLE MASTER RM100: it will be taken to around 2500 m above sea level where it will again make a major contribution to the construction activities. As, however, the transport capacities of the second material cableway are lower compared to the first one, the enormous benefits of the impressive weight-to-performance ratio will be of particular value.
The Linthal 2015 project
The existing plants of the Linth-Limmern (KLL) power stations generate 450 MW of energy. The Linthal 2015 project will see this figure increase considerably:: the plan is for this pumped-storage power station to produce around 1,450 MW of electricity by the end of 2015. The aim is to secure the electricity supply to north-east and also central Switzerland also in the future. With an investment of 2,1 billion sFr (2,2 billion $), Linthal 2015 is the most outstanding hydroelectric power project and currently the largest construction works in the energy sector in Switzerland. Five years have been scheduled for construction. Up to 250 people will be working on various job sites throughout the construction phase.
