The world´s highest elevator test tower is located in Japan with a height of over 200 m. On a surface area of 25 m x 20 m, nine elevator shafts are available for Hitachi engineers to carry out extensive testing on the latest and future generations of transport technology. Ensuring safety and reliability are not just the highest priorities for elevators: the construction of the tower´s concrete frame also took place with safe and reliable formwork and scaffold systems.
For forming the shaft walls with thicknesses between 0.30 m and 1.00 m, the PERI solution relied on VARIO GT 24 girder wall formwork. The formwork elements were combined internally with CB 240 climbing scaffold to create large-sized moving units. Externally, the VARIO was hydraulically climbed from cycle to cycle using ACS selfclimbing technology - without requiring a crane and in all weathers.
The detailed execution plan of both climbing formwork variants took into consideration the fact that the wall thicknesses continuously taper and the ground plan changes at a height of 110 metres. Steel frames fitted to the inner side of the shaft also affected the formwork and climbing platform arrangement.
“Through the use of the PERI ACS climbing formwork, we can also achieve quality and safety at great heights. In addition, the number of
components which are to be moved is minimized due to the large-sized formwork units.”
