PURPOSE: To allow a passing operation and to obtain a high operating efficiency by providing plural elevator shafts in which the secondary conductor of a linear motor is buried vertically or horizontally to the side wall, and composing the system to allow to transfer a cage to a neighboring shaft along a bypass secondary conductor.

CONSTITUTION: Elevator shafts 31 and 32 which have a size to arrange three cages 10 are provided in two lines, and one side shaft 31 is used for the upward operation while the other side shaft 32 for the downward operation. While secondary conductor passages 70a to 70c for vertical movement are lined parallel to the shafts 31 and 32, bypass secondary conductors 71 for traverse to make the cage convert the secondary conductor passage are buried at plural positions between the neighboring secondary conductors for vertical movement. On the other hand, while a primary coil 20 positioning opposite to the secondary conductor buried in the shafts 31 and 32 is provided to the side surface of the cage 10, four wheels 40 steered while maintaining the cage in the horizontal condition when the cage is transferred from the present shaft to the neighboring shaft are provided respectively to the side surface where the primary coils 20 are provided.
