<p>A driving engine of a lifting system and an installation method of the driving engine are provided to improve assembling efficiency, and to align the driving engine conveniently by installing a driving unit near a guide rail and reducing the size of the driving engine. A lifting chamber, a balance weight and a driving engine(20) are installed in a path(10), and the lifting chamber and the balance weight are operated with driving units(3,3'). The driving engine includes a driving shaft(4), the driving units, a motor(1) and a brake(2). Supporting and driving units(19,19') are installed corresponding to the gap of the driving units, and the driving units are integrally formed with the driving shaft and directly machined. The driving shaft is installed by a central bearing operated in a symmetrical surface of the driving units, and the inner diameter of the central bearing is formed to be larger than the outer diameter of the driving units.</p> |
