To provide a support structure for hoisting a climbing crane, which can reduce a weight by minimizing a bending load acting on horizontal members and the number of components so as to reduce an amount of work and the number of days required for assembly and disassembly.SOLUTION: A support structure for hoisting a climbing crane 1, comprising a cross base 3 on which a mast 2 is erected, and a guide mast 4 that can be raised and lowered along the mast 2, includes a base support structure base 5 having a leg 7 constructed by arranging a mountain-shaped truss structure 6 so as to surround the mast 2 from all sides and connecting adjacent lower ends, a rectangular base horizontal frame 8 whose four corners are horizontally supported by tops of the truss structures 6 and which supports four tip ends 3a of the cross base 3 at the four corners during climbing, and a base support frame 9 which is erected at the four corners of the base horizontal frame 8 so as to straddle the tip ends 3a of the cross base 3, and can connect protruding pieces 4a protruding from the guide mast 4 to upper side surfaces to support them.SELECTED DRAWING: Figure 1
【課題】水平材に作用する曲げ荷重を最小限に抑えて軽量化を図り且つ部品点数を減らして組立・解体時における作業量や日数の削減を図り得るクライミングクレーンの昇降用支持構台を提供する。【解決手段】マスト2が立設される十字架台3と、マスト2に沿って昇降自在なガイドマスト4とを備えたクライミングクレーン1の昇降用支持構台に関し、山形を成すトラス構造体6をマスト2を四方から取り囲むように配置し且つ相互の隣接する下端同士を連結して構築した脚部7と、各トラス構造体6の頂部により四隅を水平支持され且つクライミング時に十字架台3の四つの先端3aを四隅で支持する矩形枠状のベース水平枠部8と、該ベース水平枠部8の四隅に十字架台3の先端3aを跨ぐように立設され且つガイドマスト4から張り出される突片4aを上部側面に連結して支持し得るベース支持フレーム9とを有するベース支持構台5を備える。【選択図】図1
