Автоматические лифты начинают появляться уже в 1930-х годах, поскольку их развитие ускорилось из-за того, что поразительные операторы лифтов поставили на колени крупные города на небоскребах (и, следовательно, их лифтах), таких как New Your и Chicago. Эти электромеханические системы использовали релейные логические схемы повышенной сложности для управления скоростью, положением и работой ворот лифта или группы лифтов. Система Otis Autotronic начала 1950-х годов создала самую раннюю систему прогнозирования, которая могла предвидеть схемы движения внутри здания, чтобы наиболее эффективно использовать движение лифта. До 1980-х годов элеваторно-управляемые лифтовые системы оставались обычным явлением, и их постепенная замена твердотельными микропроцессорными средствами управления теперь является отраслевым стандартом. Большинство старых лифтов с ручным управлением были оснащены автоматическим или полуавтоматическим управлением.
