LOWER TRAVELING BODY OF MOBILE CRANE
To provide a lower traveling body of a mobile crane that can reduce deflections that are caused in a crawler frame when a suspended load is suspended in an upper turning body on the front side or the rear side of the lower traveling body.SOLUTION: A connection part of a lower travelling body 101 is configured so that a right-front straight line LA which passes any point included in a front-side load reception surface and any point included in a right-front load transmission surface passes a right-front end roller 261 or a front side of the right-front end roller 261, and a left-front straight line LC which passes any point included in the front-side load reception surface and any point included in a left-front load transmission surface passes a left-front end roller 261 or the front side of the left-front end roller 261, in a planer view.SELECTED DRAWING: Figure 3
【課題】下部走行体よりも前側又は後側において上部旋回体に吊り荷が吊るされたときにクローラフレームに生じるたわみを小さくすることが可能な移動式クレーンの下部走行体を提供する。【解決手段】下部走行体１０１の連結部は、平面視において、前側荷重受面に含まれる何れかの点と右前荷重伝達面に含まれる何れかの点とを通る右前直線ＬＡが右前端ローラ２６１又は右前端ローラ２６１よりも前側を通り、前側荷重受面に含まれる何れかの点と左前荷重伝達面に含まれる何れかの点とを通る左前直線ＬＣが左前端ローラ２６１又は左前端ローラ２６１よりも前側を通るように構成される。【選択図】図３
