Grünberg cable car
Coordinates: 47 ° 54 ′ 48.3 " N , 13 ° 48 ′ 28.8" E
The Grünbergseilbahn is a cable car that leads to Gmunden's local mountain, Grünberg . The facility has existed since 1957 and has carried over six million passengers since then. The original two-cable gondola lift was dismantled in 2013, and the new aerial tramway , which opened in 2014, was built in its place .
Operator of the plant is the Traunsee Touristik GmbH , a subsidiary of Upper Austria Seilbahnholding , which in turn is a branch holding the Upper Austrian Holding , the investment management of the province of Upper Austria is.
Bicable gondola (1957 to 2013)
The original gondola was a two-cable gondola based on the Wallmannsberger system , which was built by VÖEST , and it was also the last of this system to be preserved in Europe. Construction began in 1956 and the ceremonial opening took place on September 14, 1957. The drive was arranged in the mountain station, the guy ropes for the pulling and carrying ropes with the tension weights in the valley station. At that time, the length of the first span from the valley station to the first support , which was 1396 m, was unusual . The railway had a total of three supports. In addition to the 18 gondolas that were initially available, eight more gondolas of the same system from the inventory of the Stubnerkogelbahn in Bad Gastein were purchased in 1973 in order to increase the passenger capacity from 180 people per hour in each direction to 300 people / h, as the capacity limit had been reached. In the years 2000 and 2001 the system was subjected to a fundamental overhaul and partial renewal. The suspension ropes, the drive, the gearbox and the electrotechnical equipment were renewed and the gondolas at Carvatech and the drives by Garaventa were overhauled. The installation of new suspension ropes was necessary because the reserve rope , an excess length of the ropes kept untensioned in the mountain station, had been used up by the regular relocation of the suspension ropes.
Although a cable car license was in place until 2017, the 2010 national holiday was the last day of operation of the facility, as it had reached the end of its service life. The very last public trip was auctioned on Ebay for charity. The original intention to dismantle the cable car and build the new one immediately was not implemented because objections from the property owners regarding the passage rights of the new construction had to be clarified. The dismantling of the plant began in spring and early summer 2013 only after an agreement was reached with all those affected. On May 15, 2013, 17 Dorotheum gondolas were auctioned at the valley station . Then the dismantling of the station building and the supports began. In June 2013 the old suspension ropes were finished. The auxiliary ropes used to pull out the old ropes initially remained taut at the position of the former rope route at auxiliary anchors, as these were used in spring 2014 for the rope pull of the new aerial tramway.

Accident 2004
On October 16, 2004, at around 1 p.m., an accident occurred in which two people were seriously injured. After exiting the valley station, an unoccupied gondola detached itself from the pulling rope and slid about 150 m downhill on the carrying rope. The gondola sliding down the valley collided with a gondola that had just left the station and was occupied by a woman and her grandchild. The three-year-old child was thrown out of the gondola window by the impact, fell eight meters into the parking lot of the train and was critically injured in the process. The grandmother was thrown to the bottom of the gondola and also seriously injured. The cause of the accident was a malfunction (“pinch clutch”) of the empty nacelle that had slipped back.
New aerial tramway since 2014
On May 18, 2013, the groundbreaking ceremony for the new large cable car to the Grünberg took place with the participation of Governor Josef Pühringer . The cost of the project was around 10 million euros, which was borne by the state of Upper Austria through OÖ Seilbahnholding .
The new aerial tramway was opened on June 14, 2014. The barrier-free lift largely uses the route of the dismantled gondola lift.
Due to the limited space at the valley station, the central axes of the two lanes are not parallel, but have a track width of only 90 cm in the valley station in order to reduce the overall width of the station building. For this, the track width at the first support is 10.25 m, in order to create enough distance for the gondola to meet halfway through. Automatic sliding platforms were installed in the valley station to bridge the gaps of different sizes between the gondola door and the fixed platform, depending on whether a gondola drives in on the left or right cable route. The valley station itself had to be built on a bored pile foundation of 35 piles with a depth of up to 17 m in order to transfer the forces in stable subsoil.
The four suspension ropes on this lift are not tensioned using tension weights , but are firmly anchored to rope bollards at the mountain and valley stations. The pull rope is an endlessly spliced loop to which the gondola drives are attached with rope clamps. This makes it possible to dispense with a safety brake device.
The train can be operated at the lower speed of 5.5 - 7 m / s to save personnel without a car attendant. Only the two stations are then occupied. The maximum speed when crossing the support is 8 m / s. If car attendants travel with them, the system can be operated at 10 m / s. The cabins offer space for 45 people in unaccompanied normal operation. If the number of passengers is high, 60 people and the then obligatory companion can be transported. The gondolas can be flexibly equipped with a quick-change system with 24 seats; There are special load openings on the front of the gondolas for the transport of long goods such as the ascent of hang gliders .
