COUNTERWEIGHT SUPPORTING STRUCTURE IN CONSTRUCTION MACHINE
PROBLEM TO BE SOLVED: To improve position accuracy of a counterweight attachment seat surface and a fastening hole provided on a counterweight supporting part when a counterweight is supported on the counterweight supporting part via a fastening bolt.SOLUTION: A counterweight supporting part 16 is constituted by a supporting plate 17 erectly fixed on a rear portion of a revolving frame 9, and a support member 18 attached to the supporting plate 17 fixed to the revolving frame 9. The support member 18 is constituted by a base member 20 fitted and fixed in such a manner of freely adjusting a longitudinal position with respect to a through hole 17a opened to the supporting plate 17 and having a counterweight attachment seat surface 20a, and a bolt fastening member 21 fixed in such a manner of freely adjusting a vertical and lateral position with respect to the base member 20 and having a fastening hole 21a to which a fastening bolt 15 is fastened.SELECTED DRAWING: Figure 3
【課題】カウンタウエイトをカウンタウエイト支持部に締結ボルトを介して支持する場合に、カウンタウエイト支持部に設けられるカウンタウエイト取付け座面および締結孔の位置精度を向上させる。【解決手段】カウンタウエイト支持部１６を、旋回フレーム９の後部に立設固定される支持プレート１７と、旋回フレーム９に固定された状態の支持プレート１７に取付けられるサポート部材１８とを用いて構成するとともに、該サポート部材１８を、支持プレート１７に開設された貫通孔１７ａに前後位置調整自在に嵌合固定され、カウンタウエイト取付け座面２０ａを有するベース部材２０と、ベース部材２０に上下左右位置調整自在に固定され、締結ボルト１５が締結される締結孔２１ａを有したボルト締結部材２１とから構成した。【選択図】図３
