LOWER TRAVELING BODY OF MOBILE CRANE
To provide a lower traveling body of a mobile crane that can reduce deflections that are caused in an axle 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: In a lower traveling body 101, a right crawler frame 2R includes right load receiving parts 21R and 22R protruding to a left side from detachment sites 201 and 202 of a right frame main body 20R, and a left crawler frame 2L includes left load receiving parts 21L and 22L protruding to a right side from detachment sites 203 and 204 of a left frame main body 20L. The right load receiving part 21R and the left load receiving part 21L receive downward loads from intermediate parts M1 and M1 of right-front and left-front axle parts 11R and 11L and support the right-front axle part 11R and the left-front axle part 11L. The right load receiving part 22R and the left load receiving part 22L receive downward loads from intermediate parts M2 and M2 of right-rear and left-rear axle parts 12R and 12L and support the right-rear axle part 12R and the left-rear axle part 12L.SELECTED DRAWING: Figure 7
【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アクスルに生じるたわみを小さくする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では、右クローラフレーム２Ｒは、右フレーム本体２０Ｒの外れ部位２０１，２０２から左側に突出する右荷重受部２１Ｒ，２２Ｒを含み、左クローラフレーム２Ｌは、左フレーム本体２０Ｌの外れ部位２０３，２０４から右側に突出する左荷重受部２１Ｌ，２２Ｌを含む。右荷重受部２１Ｒ及び左荷重受部２１Ｌは、右前及び左前アクスル部１１Ｒ，１１Ｌの中間部Ｍ１，Ｍ１から下向きの荷重を受けて右前アクスル部１１Ｒ及び左前アクスル部１１Ｌを支持する。右荷重受部２２Ｒ及び左荷重受部２２Ｌは、右後及び左後アクスル部１２Ｒ，１２Ｌの中間部Ｍ２，Ｍ２から下向きの荷重を受けて右後アクスル部１２Ｒ及び左後アクスル部１２Ｌを支持する。【選択図】図７
