Heavydrive replaces a pane in a tight space on the St. Jakobshalle arena in Basel
Within just half a day Heavydrive GmbH had replaced a 6.5m tall x 2.8m wide pane on the St. Jakobshalle arena in Basel (Switzerland). The challenge of this project was that it had to be assembled under a 3m deep overhang. The 1.5 tonne pane also had to be inserted into a transom-mullion construction, and on a downward-sloping surface! What’s more, the frosty temperatures and strong winds didn’t make assembly any easier.
For this tricky project, the Tapfheim-based company delivered two vacuum suction systems to Switzerland: the VSG 1500 KMH with a lifting capacity of up to 1.5 tonnes, and the VSGU 1600 for the overhead assembly of panes weighing up to 1.6 tonnes. The VSGU 1600 was attached to the Heavydrive MRK 195.0 assembly crane. Using the overhead manipulator, the suction feature gripped the damaged pane in the centre, lifted it under the 3m overhang and took it out. Even the sloped surface, at an angle of about 15 degrees, didn’t pose a problem to the Heavydrive crane. The operator could balance on the sloped surface with the MRK crane’s four axles as well as a further three axles on the manipulator.
By remote control, the Heavydrive operator lifted the new pane directly from the wooden transport crate and guided it into the opening. The VSGU 1600 with 3-axle manipulators lifted the triple-glazed insulating glass pane from Thiele Glas under the overhang and placed it accurately into the transom-mullion construction.
The St. Jakobshalle arena in Basel (Switzerland) was designed by architect Giovanni Panozzo and opened in 1976. The building is used for indoor sports and concert events. From 2015 to 2018 St. Jakobshalle was renovated and modernised. Now the protruding canopy roof gives this building its distinctive look.
