As explained above, in the present invention, the conventional brake device installed coaxially with the sheave in the machine room is not used.
It is not affected by the abnormal wear phenomenon that occurs between the sheave and the main rope, and moreover, during normal stops that occur frequently,
The stopping operation is performed by electrical control of the linear motor until the car comes to a stop, and the braking mechanism is used only to maintain the stopped state, so this braking mechanism installed at the bottom of the car prevents the heel from moving relative to the rail. There is no friction and no abnormal wear occurs. Furthermore, when the car malfunctions, this braking mechanism acts as an emergency stop device in the same way as in the past, and there is no need to separately equip a brake device and an emergency stop device as in the past, making it possible to realize an elevator with a simple configuration. .
