現在在芝加哥高達1127英尺的「詹漢考克中心」 (John Hancock Center) 裡的電梯,以一分鐘1800英尺的上升!由於鋼鐵結構的發明,興建摩天大樓也不是夢想了。位於芝加哥市的十層「家庭保險大樓」 (Home Insurance Building) 1885年興建,被認為是當時全世界最高的大樓,共有四部電梯。而1913年興建的伍爾沃斯大樓 (Woolworth Building) ,高約792英尺,共有26部電梯;1931年興建完成的「帝國大廈」 (Empire State Building) ,高約1250英尺,共有58部電梯。因為有這些新的高聳建築物不斷興建,後來由歐提司的兒子管理的歐提司電梯公司,生意也有穩定的成長。

Today the elevators in Chicago's 1,127-foot John Hancock Center soar upward at 1,800 feet per minute! With the introduction of steel frame construction, the skyscraper became possible. The 10-story Home Insurance Building in Chicago, built in 1885, was considered the world's first tall building, requiring four elevators. The 1913 Woolworth Building (792 feet) boasted 26 elevators; the 1931 Empire State Building (1,250 feet) required 58. With new and taller buildings, business at the Otis Elevator Company, later run by Otis's sons, rose steadily.
