Germany, Bargteheide – Quality and performance strength to endure the harsh conditions high up on a mountain

 

When using heavy machinery for construction work in the Alps, it comes down to two things: quality and performance strength. This is the only way for the machines to endure the harsh conditions high up on a mountain.

Industrial gear units in the Swiss Alps

The expansion project Linthal 2015 in the Swiss Alps demonstrated that industrial gear units from NORD have what it takes.

For this project, an underground central chamber for a new pumped storage power station is being built at an altitude of about 1,700 m and 600 m inside the mountain.

Pump water to power the turbines that genarate electricity

It will pump water from the existing Limmernboden reservoir at an altitude of 1,860 m to the 600 m higher Muttsee in order to power the turbines that generate electricity. The excavated rock from two new chambers had to be conveyed out of the mountain.

 The NORD SK 12407 industrial gear units were on continuous duty.

Two Nord industrial gear units

For this purpose, two NORD SK 12407 industrial gear units were on continuous duty. These two NORD industrial gear units powered conveyor systems in a sub-station transporting 500 t of excavated material per hour with an extreme incline of 45 degrees and a height difference of approximately 180 m. The excavation of the rock was carried out continuously in an intensive 24/7, 3-shift operation.

Trasport of rock at high altitudes in an Alpine environment full of dust

Any downtime of the machinery would have put the project schedule at risk. Industrial gear units from NORD easily managed the transport of 2,445,000 m³ of rock at high altitudes in an Alpine environment full of dust. The project manager was extremely satisfied not only with NORD DRIVESYSTEMS but also for its exclusively produced modular industrial gear units.

Ten weeks from ordering to delivery of the drives

The output torque was of up to 290,000 Nm in a one-piece UNICASE housing: “It only took ten weeks from ordering to delivery of the drives.” In addition to that, the good cost-benefit ratio in combination with excellent consulting and perfect customer service impressed the Swiss who are known to aim for accuracy and perfection.
