REVOLVING FRAME FOR CONSTRUCTION MACHINE
PROBLEM TO BE SOLVED: To provide a revolving frame for a construction machine, for preventing cracking in a skirt plate by dispersing stress on the skirt plate when a torsional load is applied thereto.SOLUTION: A revolving frame 22 includes a bottom plate 30, a pair of left and right vertical plates 32, 34 erected on the bottom plate 30 and extending in the longitudinal direction, a plurality of left supporting members 36 extending out of the outer face of the vertical plate 32 located on the left side in the left direction, and a left skirt plate 40 connected to the extending ends of the plurality of left supporting members 36 and extending in the longitudinal direction, the plurality of left supporting members 36 including a rear cab supporting member 36b for supporting a cab 24 at its rear side, the rear cab supporting member 36b having a front plate 56, a back plate 58, a top plate 60 and a bottom plate 62, the top plate 60 being formed with a first slit 60d slenderly extending in the horizontal direction.SELECTED DRAWING: Figure 3
【課題】捩じり荷重が作用したときにスカート板に生ずる応力が分散され、スカート板に亀裂が入ることが防止される建設機械の旋回フレームを提供する。【解決手段】旋回フレーム２２は、底板３０と、底板３０上に立設され且つ前後方向に延びる左右一対の縦板３２，３４と、左側に位置する縦板３２の外面から左方向に延出する複数の左サポート部材３６と、複数の左サポート部材３６の延出端の各々に接続され且つ前後方向に延びる左スカート板４０とを含む。複数の左サポート部材３６には、キャブ２４の後側を支持する後キャブサポート部材３６ｂが含まれる。後キャブサポート部材３６ｂは、前面板５６、背面板５８、天面板６０及び底面板６２を有する。天面板６０には、左右方向に細長く延びる第１のスリット６０ｄが形成されている。【選択図】図３
