To provide a counterweight supporting structure for preventing falling of the counterweight when a fixture breaks.SOLUTION: A counterweight supporting structure 5 has a supporting part 61 provided to the revolving frame of a construction machine and a counterweight 32 fitted to the supporting part 61 using a fixture. The counter weight 32 has an engagement part 74 protruded to the supporting part 61 side, and the supporting part 61 has an engaged part 64 engaged with the engagement part 74. The engaged part 64 has a recessed part 64U, and at least one part of the engagement part 74 is engaged with the recessed part 64U. The counterweight supporting structure 5 has a fixing member 66 for fixing the engagement part 74 to the engaged part 64.SELECTED DRAWING: Figure 9
【課題】取付具が破損した場合のカウンタウェイトの脱落を防ぐことを目的とする。【解決手段】カウンタウェイト支持構造５は、建設機械の旋回フレームに設けられた支持部６１と、取付具を用いて支持部６１に取り付けられたカウンタウェイト３２と、を備え、カウンタウェイト３２は、支持部６１側に突出した係合部７４を備え、支持部６１は、係合部７４が係合する被係合部６４を備える。被係合部６４は、凹部６４Ｕを備え、係合部７４の少なくとも一部分が凹部６４Ｕに係合する。カウンタウェイト支持構造５は、係合部７４を被係合部６４に固定する固定部材６６を備える。【選択図】図９
