載のクライミングクレーン。[Scope of Claim for Utility Model Registration] (1) Depending on the height of the crane section that moves up and down along the mast erected on the pedestal, the mast and the adjacent building structure, etc. can be connected using restraining cable members. In the climbing crane that is connected and supported, the mast is rotatably supported on the pedestal, and a locking means for restricting the turning of the mast is provided, and the mast is connected to a building structure or the like by the restraining rope member. The climbing crane is characterized in that, when the mast is rotated, the locking means is released and the mast is rotated about its axis. (2) The climbing crane according to claim 1, wherein the mast is pivotally supported on a pedestal by a radial bearing and a thrust bearing so as to be rotatable about its axis. (3) In the above-mentioned utility model registration claim, the locking means is constituted by a flange member provided at the lower part of the mast and a wedge member insertably provided between the flange member and the pedestal. Climbing cranes described in scope 1.
