Hitachi Elevator Test Tower
Hitachinaka, Ibaraki, Japan
The world’s highest elevator test tower, with a height of more than 200 meter, was constructed in Hitachinaka City, Ibaraki Prefecture in Japan. Here PERI Japan K.K. is providing the general contractor Shimizu Corporation and both the subcontractors Yokogawa Construction Co Ltd. and Murakami Komuten Ltd. with its climbing and formwork systems. The completion is planned for Spring 2010.
Office buildings are getting taller and larger all around the world. The demand for safe and reliable elevators with high speed and high capacity has been increased for the last decades. Mito Works of Hitachi Ltd. is the center of research, development, and manufacturing of Hitachi’s elevator business. They are developing and testing Hitachi’s new elevators using their 90 meter high testing tower so far.
The newly constructed elevator test tower will have nine hoist ways; one of them will be an ultra high speed elevator that allows conducting tests for a new generation of elevators with a maximum speed up to 1,300 meter per minute. Hitachi is not only concerned with the research and development of technology for increased safety, but also with the reliability and the comfort of the elevators of the future.
For this project approximately 900 square meter of concrete wall is being constructed by using PERI’s Climbing Systems and the VARIO Wall Formwork with a height of 5.1 meter. The VARIO Wall Formwork System is supported by both the ACS (Automatic Climbing System) and the CB240 Climbing System. The climbing cycle is eight days for 41 climbing sequences.
14 ACS units are used for the exterior part of the construction, and 16 units of CB240 for the interior part. The building’s shape changes at 110 meter. Thus two ACS units have to be modified to meet the different shapes. At that height twelve ACS units and ten CB units will be used until the final height of 203 meter will be reached.
The building’s wall thickness is steadily decreasing from 700 mm to 300 mm; further features of this project are the steel frames set in the interior part and in the columns.
In general, scaffolding and formwork is being prepared and constructed separately in Japan. However, by using the ACS and CB 240 Systems PERI Japan K.K. offers a combined solution with which the involved contractors are able to shorten the construction period and to minimize the number of workers needed at the jobsite.
It is the target of PERI Japan K.K. to propose the best technical solution while always bearing in mind to ensure maximum safety and economical advantages of the formwork construction.

“As we're using PERI ACS system with scaffolding and formwork together, we can also concentrate on quality and safety control, even in the high-rise level. PERI Plywood can be used for approx. 40-70 times. Furthermore, because of the large VARIO panels, the amount of components could be minimized.”
