In idyllic Grossarl, on the site of the former Hochbrand 8-seater gondola lift, the new centrepiece of the Grossarltal-Dorfgastein ski area was recently created with an investment volume in the multi-digit million range. The construction of the Kieserlbahn marks the creation of one of the most advanced gondola lifts in Austria. The new 10-seater gondola lift enables visitors to reach the Kieserl summit plateau at 1954 metres above sea level in just 15 minutes.
The newly designed valley station offers a comprehensive service centre, which includes a sports shop, a spacious ski depot, a bistro, office space as well as an underground car park and flats for staff. In addition, the upper section of the mountain station has a panoramic restaurant with spectacular views.
From the outset, a high priority was placed on nature conservation as part of the planning, with extensive measures such as the creation of biotopes, larch willow projects, capercaillie habitats and dry stone walls as compensation. In addition, the operation of the lift is sustainably supplied with green electricity from hydropower.
For the construction of the lift supports and the valley station, Josef Kaiser Bau GmbH opted for the reliable formwork systems and scaffolding from RINGER in order to achieve the highest standards of quality and safety.
Formwork for the V-lift columns
The gondola lift extension and retraction support plays a key role in ensuring safety when the gondolas are transferred from the station to the ropeway system. It also supports the cable car support heads with deflection pulleys that guide the haul rope, which in turn supports the weight of the gondolas.
The formwork for this special support was erected using the extremely robust Steel Master steel frame formwork. The construction comprised double-sided formwork that reached up to around 8 metres high in places. The element composite consisted of large-format elements measuring 330 x 240 cm, supplemented by smaller modules.
Several RINGER push-pull props on both sides were used to support the huge formwork element surface. For the sloping end faces, formwork panels were fixed at the respective angle with H20 beams and various 20 kN floor props with a maximum extension length of 550 cm.
To support the formwork and reinforcement work, RINGER double railing scaffolding was also used on one side of the column formwork. Concreting was carried out with concreting platforms "L" suspended in the formwork.
Building column formwork
The large column structures below the gondola house in the valley station building were also formed using the RINGER Steel Master System. Work began with the erection of the reinforcement up to the required height, supported by the RINGER double railing scaffolding system. This was erected around all four sides of the columns, ensuring a comfortable and safe working environment. Once the reinforcement was complete, the Stahl Master elements were lifted into the scaffolding structure by crane and assembled.
The steel Master wall formwork also proved to be the ideal system for the operations building and the valley station itself. Climbing platforms were also integrated into the formwork as fall protection to ensure safety.
The commissioning of the Kieserlbahn in December 2023 was the culmination of years of planning and construction work, opening a new chapter for the Grossarltal-Dorfgastein ski area with one of the most modern cable cars in Austria.
