  • Patent number: 6062344
    Abstract: In an elevator system, first and second car carrying bases move up and down along first and second segments of a hoistway, respectively. First and second support members are located on the first and second car carrying bases, respectively. A car is moved up and down within the hoistway while being selectively supported by the first or second car carrying base. The first and second car carrying bases are arranged so as not to overlap each other when projected on a horizontal plane. Each car support member can shuttle between a support position and a nonsupport position, the support position being a position at which the car support member supports the car by projecting into a moving path of the car and the nonsupport position being a position at which the car support member is retracted from and is outside of the moving path of the car.
