PROBLEM TO BE SOLVED: To provide a counterweight fitting device capable of connecting a connector and a counterweight without precisely executing work for adjusting a position of a construction machine and a position of the counterweight, and capable of fitting the counterweight to a predetermined position of the construction machine by adjusting a position in the width direction.SOLUTION: A counterweight fitting device 18 includes a link 28 connected to the rear end of a hydraulic excavator 2 via a bracket 26 so as to be free in the elevation movement and a pair of connectors 32 and 32 arranged on the tip of the link 28. The connectors 32 comprise a pair of connection pieces 38 and 40 extending from a bearing part 36 connected to the link 28 so as to be freely turnable around the central axis O extending in the width direction and freely tiltable to the central axis O, a connection pin 42 detachably connected between extension end parts of the respective connection pieces 38 and 40 and a pair of position adjusting members 44 and 45 projecting from an extension end part inner surface of the respective connection pieces 38 and 40.SELECTED DRAWING: Figure 4

    【課題】建設機械の位置及びカウンタウエイトの位置を調整する作業が精密になされていなくても連結具とカウンタウエイトとが連結し得ると共に、幅方向の位置を調整して建設機械の所定の位置にカウンタウエイトを装着し得る、カウンタウエイト装着装置を提供する。【解決手段】カウンタウエイト装着装置18は、油圧ショベル2の後端にブラケット26を介して俯仰動自在に接続されたリンク28と、リンク28の先端に配設された一対の連結具32,32とを含む。連結具32は、幅方向に延びる中心軸線Oを中心として旋回自在に且つ中心軸線Oに対して傾動自在にリンク28に接続された軸受部36から延出する一対の連結片38,40と、各連結片38,40の延出端部間に着脱自在に接続された連結ピン42と、各連結片38,40の延出端部内面から突出する一対の位置調整部材44,45とを備えている。【選択図】図4
