A passenger transport installation in which a large number of people can be efficiently transported between at least two vertically-spaced places. Stations communicate with a vertical elevator passage or passages along which vehicles can move upward and downward, and the vehicles stop at the stations to allow passagers to get on and off. While passengers get on and off the vehicles at the stations, other vehicles carrying other passengers can move upward and downwardly along the elevator passage or passages.

Passenger transport installation, vehicle for use therein, and method of

A braking device for an elevator winding machine generates a braking force by contacting a rotary body driven by a rotary shaft of the winding machine with a brake section supported through the intermediary of an elastic body. The elastic body has a nonlinear elastic characteristic so that a starting shock to the passengers in the elevator car is prevented and the braking torque detecting accuracy is improved.

Braking device for elevator winding machine and elevator using the

An elevator apparatus includes an electric motor for driving the elevator apparatus, an elevator cage adapted to be lifted or lowered by the electric motor, a brake device for holding and retaining an elevator driving system, including the electric motor, and a malfunction detecting device responsive to the application of a torque to a retainer section of the brake device during the lifting or lowering of the elevator cage.
