  • Elevator and cleaning jig for elevator guide device
    Patent number: 8955649
    Abstract: An elevator according to an embodiment of the present invention includes a guide rail installed in an elevator hoist way in a vertical direction, an elevator car that ascends and descends along the guide rail, an elevator guide device, and a cleaning jig for an elevator guide device. The elevator guide device is fixed to the elevator car, and guides the running elevator car along the guide rail without bringing the elevator car into contact with the guide rail while a predetermined clearance is maintained with the guide rail using magnetic force generated by a magnet guide unit. The cleaning jig for an elevator guide device is installed on the guide rail to come into contact with a magnetic pole of the magnetic guide unit to remove a foreign matter attached to a surface thereof when the elevator car passes the cleaning jig for an elevator guide device.
