57 ft long Climbing Platforms on 2 ACS Brackets
Andromeda Tower in Vienna, utilizing
PERI ACS Automatic Climbing System
When completed, the Andromeda Tower will reach a height of 340'' (103.60 m) with 32 stories. The main core is 50'' x 50'' (15 x 15 m) with wall thicknesses differing between 2 and 8 inches. It consists of five separate subcores containing bathrooms, elevator shafts and a staircase.
Only four ACS platform units, each 57'' (17.30 m) long, were used on the outside. Due to the geometry of the structure, these were mounted on different core elements with the formwork panels attached asymmetrically. The system was controlled by means of two hydraulic power packs giving a lifting capacity of 45 kips (200 kN) per unit. The inside of the core was covered with 13 shaft platforms, three CB climbing platforms and a further ACS automatic climbing unit. This arrangement allows workers to move safely inside and outside the core on a single level. Extended GT 24 girders fitted with lumber provide a safety handrail system. Variable beams allow the shaft platforms to be easily adapted to the wall projections, and all of the platforms may be raised independently. Specially designed openings in the climbing units allow crane access to the lower levels for lifting the forms and materials.
