LOWER TRAVELING BODY OF MOBILE CRANE
To provide a lower traveling body of a mobile crane that can reduce deformations that are caused when a suspended load is suspended from an upper turning body on the front side or the rear side of the lower traveling body.SOLUTION: In a lower traveling body 101 of a mobile crane, a right-front load transmission part 21R and a left-front load transmission part 21L are configured so that front-side loads can be respectively transmitted from a right-front opposing part ST1 and a left-front opposing part ST3 to a right-front transmission site 201 of a right frame main body 20R and a left-front transmission site 203 of a left frame main body 20L, and a right-rear load transmission part 22R and a left-rear load transmission part 22L are configured so that rear-side loads can be respectively transmitted from a right-rear opposing part ST2 and a left-rear opposing part ST4 to a right-rear transmission site 202 of the right frame main body 20R and a left-rear transmission site 204 of the left frame main body 20L.SELECTED DRAWING: Figure 3
【課題】下部走行体よりも前側又は後側にいて吊り荷が上部旋回体から吊るされたときの変形が小さい移動式クレーンの下部走行体を提供する。【解決手段】移動式クレーンの下部走行体１０１では、右前荷重伝達部２１Ｒ及び左前荷重伝達部２１Ｌは、前側荷重を、右前対向部ＳＴ１及び左前対向部ＳＴ３から右フレーム本体２０Ｒの右前伝達部位２０１及び左フレーム本体２０Ｌの左前伝達部位２０３にそれぞれ伝達することが可能なように構成され、右後荷重伝達部２２Ｒ及び左後荷重伝達部２２Ｌは、後側荷重を、右後対向部ＳＴ２及び左後対向部ＳＴ４から右フレーム本体２０Ｒの右後伝達部位２０２及び左フレーム本体２０Ｌの左後伝達部位２０４にそれぞれ伝達することが可能なように構成される。【選択図】図３
