    • PROBLEM TO BE SOLVED: To provide a climbing method of a climbing crane capable of supporting reaction force of a several hundred tons of a large-sized crane by an RC structural beam, in a very high RC structural building.
      SOLUTION: In the climbing method of the climbing crane, a reinforcing plate 13 supported by a column 1 is provided in a lower side of a PC beam 2 on which a base frame 10 of a mast 8 lower end portion is temporarily constructed and in a lower side of a PC beam 2 on which a hoisting/lowering device 11 of the climbing crane 5 is temporarily constructed. On the PC beam 2 on which the base frame 10 installed with the reinforcing plate 13, the mast 8 is slid up by the hoisting/lowering device 11 to install the base frame 10.
