PURPOSE: A lifting device of a gondola magnifies the range of expansion of a cage and a counterweight and changes the position of a rope according to the position movement of the cage and the counterweight, thereby remarkably reducing the serious shake and improving the safety of the working and boarding. CONSTITUTION: A lifting device of a gondola comprises a pair of cage arms(2), a pair of counterweight arms(3), an interlocking part and a rope. A pair of cage arms(2) are positioned in parallel at the intervals on a frame(1), connect a circularly rotating sprocket(24) in the middle of a first, second and third cage arm members(21,22,23) and sprockets(25,26,27) with a chain(28) and expand in multi stages by the chain(28) transmission. A pair of counterweight arms(3) are positioned in parallel at the intervals in a pair of cage arms(2), connect a circularly rotating sprocket(34) in the middle of a first, second and third counterweight arm members(31,32,33) and a sprocket A, B and C(35,36,37) with a chain(38) and stretch in multi stages in the inverse direction of the cage arm(2) by the chain(38) transmission. The interlocking part interlocks the cage arm(2) and the counterweight arm(3) with the driving force of a driving motor. The rope connects respectively the cage(6) and counterweight(7) which are positioned on the cage arm(2) and counterweight arm(3) respectively. |
