Abstract: An emergency stop apparatus for an elevator having a simple structure as well as effectiveness, which may facilitate to reduce manufacturing and maintaining cost.

Abstract: Disclosed is an elevator having covers capable of minimizing a generation of turbulent flows at upper and lower portions of the elevator cabin so as to reduce noise and vibration during the operation of the elevator. The elevator according to the present invention comprises upper and lower horizontal supporting members made of shaped steels having a L shape in cross section and plate strips, and covers having a dome and a truncated pyramid shape. In the elevator according to the present invention, the covers can temper impacts, due to air flows in a hoistway, against the elevator cabin during the operation of the elevator. As a result, noise and vibration due to the impacts can be reduced.
