A balancing device for a gondola comprises an arm, a pair of wires(5), a cage, a pair of winding drums(7,8), a body(10), a pair of balls(15), a pair of sensors(20,21), and a control unit(30). The arm is extended out of a building(1) from the rooftop. The wires are extended downward along an outer wall of the building through a front end of the arm. The cage is hung on lower ends of the wires. The winding drums ascend or descend the cage by winding or unwinding each wire by a pair of driving motors(M1,M2). The body is fixed to the cage, wherein a pair of horizontal moving paths(11,12) whose lower surfaces are inclined downward and closed ends(13) face each other. The balls reciprocate on each horizontal moving path. The sensors are provided on each open end(14) of the horizontal moving paths to sense the contact of the balls. The control unit controls the driving motors by signals from the sensors to lift the cage in a horizontal state. Each horizontal moving path is formed on the same imaginary line orthogonal to each wire.
