A lift device includes a cable member having opposed ends thereof suspended via guide members and longitudinally movable by a lift drive unit, a lift unit connected to one of the ends of the cable member for lifting an object along a lift passage, a balance weight connected to the other end of the cable member and movable along a balance-weight lift passage, a detection device for detecting a height of the balance weight to check whether or not the balance weight is positioned higher than a lower end of the balance-weight lift passage by a predetermined value when said lift unit is moved to its uppermost position, and a warning device for warning an abnormal elongation of the cable member if the detection device detects that the balance weight is not positioned higher than the lower end of the balance-weight lift passage by the predetermined amount. The invention also discloses an automated high-raised parking system using this lift device. |
