Promenade lift
Pier and elevator

The Promenadenlift is a public passenger elevator in Baden in the canton of Aargau . It leads from Bahnhofplatz down to the Limmat promenade and overcomes a height difference of 27 meters. Together with an adjoining footbridge over the Limmat, it enables a direct pedestrian connection between Baden train station and the southern part of Ennetbaden .

description

The pedestrian connection between Baden and Ennetbaden consists of three prefabricated steel constructions , which form a design and architectural unit with Warren half-timbering , stepped Vierendeel girders and volume- forming sheet metal girders . From the southern end of the station square, which had been lengthened by twelve meters as part of this project, a 12-tonne passerelle with a span of 16.25 m leads to the lift tower, thereby balancing out the horizontal of the steep slope. Due to the carrier height of 1.60 m, it is possible to use the carrier as a railing at the same time. In this way an additional railing and handrail construction could be dispensed with.

The lift tower is 35.57 m high, its external dimensions are 4.90 × 3.10 m. The two vertical trusses with transverse reinforcements and the base made of in-situ concrete are distinctive . The two girders weigh 24 tons each, the cross-sections of the chords decrease towards the top of the tower. Together with the rear cross members, the belts form an emergency staircase. Glazing separates them from the actual elevator shaft. The elevator cabin is almost three meters high, and the engine room is at the top of the tower.

At the lower end of the lift, paths lead in three directions: northwards to the spa district , southwards towards the old town, eastwards over the Limmat to Ennetbaden. The 52-ton footbridge over the river presents itself as a simple beam. Its span is 51.82 m, with a height of 3.80 m and a width of 3.10 m. Here, too, two lattice girders form the load-bearing elements; they are connected to one another in the lower and upper chord levels by means of cross girders. The pavement made of grating rests on two secondary longitudinal girders in the lower chord level . The abutments are also made of in-situ concrete.

The promenade lift is accessible around the clock for pedestrians and cyclists, use is free of charge. There is a bike-and-ride facility on the Ennetbaden side of the footbridge.

development

For a long time, Baden and Ennetbaden were only connected by the wooden bridge and the leaning bridge . For many pedestrians and cyclists, this meant a considerable detour despite the short straight line distance. A project from 1982 envisaged the construction of a funicular between the Bahnhofplatz and the Limmatpromenade . It would have been 120 meters long and with an incline of 23% would have overcome a height difference of 27 meters. The top station was planned for the stairs in front of the reformed church , a footbridge over the Limmat was supposed to connect Ennetbaden.

In 2002, both communities presented a development plan for the spa district and the adjoining shore zone to the south as far as the old town. In 2003/04, in a design competition, they looked for a way to cross the river near the train station, which also took into account the considerable height difference between the Limmat promenade and the Bahnhofplatz. The “FACHMANN” project from the Zurich-based architecture firm Leuppi & Schafroth was awarded the contract .

In mid-March 2007, a special transporter brought the prefabricated elements here at Zwahlen et Mayr in Aigle . From the banks of the Ennetbaden, a 500-tonne crawler crane placed the bridge structure on the abutments prepared on both sides. He then placed the two elements of the lift tower on the opposite bank, where they were welded together. In April, a 120-tonne pneumatic crane inserted the passerelle from the Baden side, followed by the assembly of the lift cabin and the technical equipment in May. The inauguration of the Limmatsteg and the promenade lift took place on June 30, 2007.

Baden and Ennetbaden shared the construction costs of 4.2 million francs each half, the new connection reduced the footpath between Ennetbaden and the train station from 20 to two minutes. The Steel Construction Center Switzerland awarded the bridge-elevator combination with the Prix ​​Acier 2007 , the Swiss Pedestrian Association with the main prize of the Flâneur d'Or 2008 . The lift is used around a third more often than originally assumed. An average of around 2500 users are counted every day.
