Attaching Gondolas
A lot has happened, and our GrebenZEHN cable car is taking shape. The valley station and mountain station are completed, and the gondolas have been attached. Now, the specialists from LEITNER are working on programming, adjusting, etc., all the cable car-related matters so that around Christmas, the GrebenZEHN 10-person gondola can turn for the first time with ski guests. More details can be seen in the video below.

Splicing
Our cable was spliced. What does that mean?
In short, the two ends of the cable were connected to create a continuous cable. For this, the 70-ton heavy steel cable had to be opened at both ends and twisted together again. This process is called splicing. Due to the friction of the cable and the interweaving of the individual small ends, a break-resistant, permanent, and non-detachable connection is created. Thanks to the professionals at Rope Service Teufelberger for their excellent work, allowing our gondolas to "travel in circles" in the future.

Cable Pull
An important step took place at the beginning of November for the GrebenZEHN cable car with the cable pull. The hauling rope, weighing 70 tons, was pulled into position using a guiding rope and a lot of mechanical force. Employees of Grebenzen and LEITNER AG, as well as their subsidiaries and partner companies, had their hands full pulling the rope over a track length of approximately 2.8 km. With tension and splicing at the end of the roughly 6 km long hauling rope, a feat of strength and an i mportant step towards completion were achieved.
Currently, cable car technicians and electricians are working on the drive, various circuits, and control elements. Thus, there is nothing standing in the way of the approval process and the first operating days in December.

All Supports Installed
On October 6th, the 17 supports along the new GrebenZEHN cable car were brought to the site and directly installed by helicopter The hauling rope, weighing 70 tons, Aérospatiale AS 332, better known as the "nickname" Super Puma, with the help of several specialized teams. An important step has been taken. The spectacle also attracted the interest of many onlookers. For those who could not be there, we have prepared some photos and a video of the support installation below.

Drive Installation
It is the end of September, and the installation of cable car technology is in full swing. The drive of our new cable car is located in the mountain station. The LEITNER DirectDrive has been delivered, and the installation has begun. The pictures clearly show that it is a direct drive, which brings many advantages.
More information about the LEITNER DirectDrive:
The basis for every safe cable car ride is a reliable and powerful drive concept.
The LEITNER DirectDrive is globally unique, a drive system that was designed without a gearbox and impresses with its almost noiseless operation and exceptionally low maintenance requirements.
For more than 20 years, the gearless drive system DirectDrive, along with the frequency converter LeitDrive from LEITNER, has set standards worldwide. Customers appreciate, compared to other drives and direct drives, especially the low maintenance effort, the high reliability of the system, and the enormously high user and maintenance friendliness. In most cases, repairs can be carried out within a few hours without affecting ongoing operations. More than 250 cable car installations in over 25 countries are already equipped with this technology.
A station with DirectDrive offers the highest possible smoothness, minimal maintenance effort, and unbeatably low operating costs (no gearbox revision, no gearbox oil change). In addition, it reduces energy consumption during operation by up to 5% compared to a conventional drive.
Progress at the Valley Station
A lot is happening at the valley station as well. As you can see in the photos, the service buildings are almost finished. Even windows and doors are already installed. The formwork and concrete work of the gondola garage are progressing well. Our construction company Wagrain Bau has reached about halfway through the walls. On the mountain side, the wall has been backfilled. The first supports leading out of the valley station have also been pre-assembled and are waiting only for the support head and the roller battery.

Concrete Flight for Supports
Currently, there is a lot of activity in the air over the Grebenzen. Concrete for the support foundations is being flown in by a helicopter. Some supports are not accessible "over land." Helicopters are often used in cable car construction. The next time will be for setting up the supports…

Progress at Mountain and Valley Station
The construction work is progressing rapidly. The walls of service buildings are being concreted. Steel for reinforced concrete walls at the gondola hall is being prepared. At the track, concrete work is also being done for the support pedestals.
Especially at the mountain station, you can already see through individual parts that Leitner AG has already delivered that a cable car is being built here. Drives and rollers are already ready for assembly. The first work on the cable car technology will begin shortly.
Pipeline construction for snow reliability
Pipeline construction for snow reliability
In addition to the work on the cable car, our Grebenzen employees are diligently renewing pipelines for the snowmaking system. New lines are needed at the mountain station of the cable car. Also, for the snowmaking of the new ski slope – from the mountain station of the cable car to Starnberg 2 – we want to ensure.

Concrete, Excavators, and Iron
Excavation work, concrete, and iron preparations are continuing at all corners. Here are some insights from all areas. Individual support foundations are already finished, like that of support 16 not far from the Grebenzenhaus. At other locations for supports, the excavator is working.
01.08.2022
Start of Excavation at Valley Station
With the beginning of August, excavation work at the valley station has started. The extensive area of the valley station and the gondola garage requires a larger space than at the mountain station. Several excavators and large dump trucks from the company Karl Pitzer from Schladming are in use.
For the construction of the support foundations and the valley station, the company Wagrein Bau is responsible. Absolute professionals in the construction of lift systems,
Working on the Route
The rough clearing work has already been completed, and the harvester has already left the Grebenzen. Excavation work for the supports can now begin.

Start of Construction
In the months of May and June, all approval processes went positively. Thanks to everyone involved.
On July 11, 2022, the official start of construction for our new cable car took place. First, our construction company for the mountain station, Porr, with its regional branch, began their work.
At the same time, work on the route commenced. Woodcutting with a harvester and heavy equipment began here to carve out the path through the forest.
