Elevator test tower
An elevator test tower is a structure usually 100 to over 200 metres (300 feet to over 600 feet) tall that is designed to evaluate the stress and fatigue limits of specific elevator cars in a controlled environment. Tests are also carried out in the test tower to ensure reliability and safety in current elevator designs and address any failures that may arise.[1]
Examples of an elevator test tower are the National Lift Tower in Northampton, England; the Solae Tower in Inazawa, Japan; and the TK Elevator Test Tower in Rottweil, Germany (owned by ThyssenKrupp).
History
In 1888, Otis completed an elevator test tower at their factory in Yonkers, New York; this was possibly the first elevator test tower in the United States.[2]
