To provide a boom supporting structure capable of efficiently dispersing force transmitted to a boom.SOLUTION: A boom supporting structure comprises an outer supporting part (a first outer vertical wall 33, a second outer vertical wall 34) to support the boom (a base end boom 11) from the outside of the boom (the base end boom 11), and an inner reinforcement part (a first inner vertical wall 43, a second inner vertical wall 44) to reinforce the inside of the boom (the base end boom 11). The inner reinforcement part (the first inner vertical wall 43, the second inner vertical wall 44) is arranged at the position corresponding to the outer supporting part (the first vertical wall 33, the second outer vertical wall 34) via the boom (the base end boom 11).SELECTED DRAWING: Figure 3
【課題】ブームに伝わる力を効率よく分散することができるブーム支持構造を提供する。【解決手段】ブーム(基端ブーム11)の外側から、ブーム(基端ブーム11)を支持する外側支持部(第1外側縦壁33,第2外側縦壁34)と、ブーム(基端ブーム11)の内側を補強する内側補強部(第1内側縦壁43,第2内側縦壁44)と、を備え、内側補強部(第1内側縦壁43,第2内側縦壁44)は、ブーム(基端ブーム11)を介して、外側支持部(第1外側縦壁33,第2外側縦壁34)に対応する位置に配置される。【選択図】図3
