The Eibsee cable car was an aerial cableway between the valley station at the Eibsee and the mountain station at the Zugspitze summit . With almost 2000 m of all aerial tramways in the world, it overcame the greatest difference in altitude within a section. The operator was the Bayerische Zugspitzbahn Bergbahn AG (BZB), a subsidiary of the Garmisch-Partenkirchen municipal works . After the cable car ceased its service on April 2, 2017, it was replaced by the Zugspitze cable car in December 2017 , which runs almost the same route. The new Eibsee cable car sets three world records, namely the largest difference in overall height; In addition, it has the largest steel structural column and the longest free span.
history
The reason for the construction of a cable car from the Bavarian Eibsee to the Zugspitze was that the tourists wanted to get to the Zugspitze summit faster than was customary until then with the cogwheel, slope and summit train. It was decided to build an aerial tramway.
Construction of the Eibsee cable car by the Ernst Heckel company from Saarbrücken began in 1961. During the construction, the Heckel company merged with the companies of the two great German cable car pioneers Julius Pohlig and Adolf Bleichert to form the new Pohlig-Heckel-Bleichert (PHB). In 1961 the shell of the valley station and the two pillars were completed. Due to the unfavorable weather , construction work dragged on until the end of 1962.
During the maiden voyage on December 1, 1962, a journalist crashed into a control cabinet, which activated all the brakes not only in the valley station, but also on the drives at the same time and triggered the entire system to brake. As a result, due to the subsequent overbraking, a pulling rope threw itself over a supporting rope. The cabin had to go slowly down into the valley, which meant that the inauguration had initially failed. Two weeks later the suspension rope was thrown off in a hurricane despite safety precautions, so that additional storm protection had to be installed. A large amount of ice may have contributed to this. This delayed the start of public operations. On May 15, 1963, the railway went into public service. At that time it was already out of date with a capacity of only 300 people per hour compared to other aerial tramways of the time. This was due to the limited space at the summit and the very long inclined length of the cable car, which did not allow larger cabins.
The Eibsee cable car was owned by the Bayerische Zugspitzbahn Bergbahn AG .
Since the low transport capacity of the old Eibsee cable car sometimes led to long waiting times, a new building was considered in 2008.
In 2012, the new building was finally decided, with costs of 30 million euros expected.
After almost 54 years of operation, during which over 21 million passengers were transported, the Eibsee cable car ceased operations on April 2, 2017.
technology
The Eibsee cable car was exported after Doppeltragseil- and Doppelzugseil system aerial tramway . The valley station was designed as a drive tensioning station , while the opposite station ( mountain station ) was only a reversing frame. The drive for aerial tramways is usually located in the mountain station, as this reduces wear and tear and the necessary starting power, which in this case was not possible due to the space available at the summit. The drive group essentially consisted of the main and auxiliary drives and the emergency drive. The main drive had 750 kW , the auxiliary drive 100 kW and the emergency drive 192 kW. In the valley station there were also the service brakes attached to the cardan shaft as well as the safety brakes that acted directly on the drive rope pulley, which could be triggered by the safety circuit and which could bring the train to a standstill even when the motor was running. In 2005, the entire drive group, including the drive cable pulleys, was overhauled by the Doppelmayr company .
The two cabins each held 44 + 1 people (44 passengers and a cabin attendant). They were produced by the Zarges company in a lightweight construction, in line with the standard at the time . The cabins were connected to the 16-roller drives via the hanger , here a half-timbered hanger . The drives had four safety brakes per lane and could throw off the pulling cables in the event of danger. The running gear had a pendulum damping that reduced the swaying of the cabin in the track axis.
The drive was attached to two pull cables with a diameter of 28 mm, which were driven by the motor, by means of a fixed clamp. The four 46 mm thick suspension ropes in a fully locked design were the carrying track. The suspension ropes were tensioned in the drive station and attached to a total of four bollards on the mountain. They were never replaced, so that during their 54 years of operation only a single suspension cable set, consisting of four suspension cables, was used. The ropes ran over two supports (half-timbered construction) 65 m and 85 m high. These were dismantled in spring 2017 as a result of the new construction of the cable car.
The cramped space conditions at the summit caused another special feature of the Eibsee cable car. The lanes moved away from each other towards the mountain station, so that the platforms of the two mountain stations were in the same building, but with a separate waiting area and platform for each rope lane, 24 meters apart. The two lanes of the Eibsee cable car were also shifted lengthways by 18 meters, which is why only 4435 meters were covered in a driving game on the 4453 m long system ; the distance between the two lanes widened to 24 m up to the Zugspitze summit, so that the cabins entered separate mountain stations, which, however, were connected to one another in the building complex on the summit. The Eibsee cable car overcame an altitude difference of 1950 m; to date, this is the largest height difference of all aerial tramways ever realized in a section.
