In addition, in a preferred embodiment, in addition to the active braking by the linear motor, the bogie and the car frame are provided with some kind of carriage brake to slow down the movement of the carriage, It may be allowed to be restrained.

This means that the bogie moves by its wheels so as to approach the elevator car frame,
It will be clear from the overlapping rails as described above. The bogie can be moved by a rope drive commonly used in horizontal movement systems or by any suitable type of linear or rotary motor, but this is not important in the present invention. The position transducer shown in the present application is:
It consists of similar or separate parts, one of which may be the bogie's wave guide 63 and the marker plate 80, but apart from this, It comprises a wave guide 52 and the marker plate 77 of the car frame. Instead of being configured as a component, other forms of position transducers may be used as desired, for example, position transducers that are located in or adjacent to the hoistway. it can. This is to provide a single set of position signals indicating that the carriage is on either the bogie or the car frame. Similarly, other types of linear motors can be used. In fact, if desired, the present invention can be constructed by disposing a movable part on the carriage, but in view of the fact that the cab moves to the bogie, it is extremely difficult to drive in this way. It is.

The present invention has been shown by two sets of primary portions 59, 60 on the bogie 28 so that the bogie 28 moves in either direction. However, it will be appreciated that if desired, if the bogie moves to the right in moving the cab, only one of the primary sides 59, 60 provided is required. . The invention relates in each case to
