PROBLEM TO BE SOLVED: To effectively improve assembly workability upon implementation.SOLUTION: A construction machine comprises a revolving frame 30 and an engine frame 50 mounted to the revolving frame. The revolving frame has: a pair of right and left main frames 31 extending in a front and rear direction; a rear end frame 41 connecting rear ends of the pair of right and left main frames to each other; and a transverse member 42 bridged between lower edge parts of the pair of right and left main frames at a predetermined distance forward from the rear end frame. The engine frame has a pair of right and left longitudinal frames 54 extending in the front and rear direction at an interval that is smaller than the interval between the pair of right and left main frames in a right and left direction by a predetermined distance, and a plurality of transverse frames 57 connecting the pair of right and left longitudinal frames to each other. Each longitudinal frame of the engine frame is arranged on the inner side between the pair of right and left main frames. A front end of each longitudinal frame is mounted to the transverse member of the revolving frame, and a rear end of each longitudinal frame is mounted to the rear end frame of the revolving frame, respectively.SELECTED DRAWING: Figure 3

    【課題】組立作業性の向上を実施上有効に図る。【解決手段】建設機械は、旋回フレーム30と、旋回フレームに取り付けられたエンジンフレーム50とを備える。旋回フレームは、前後方向に延びる左右一対の主フレーム31と、左右一対の主フレームの後端部同士を連結する後端フレーム41と、後端フレームよりも所定距離前方で左右一対の主フレームの下縁部間に架設された横部材42とを有する。エンジンフレームは、左右方向に左右一対の主フレーム間の間隔よりも所定寸法小さい間隔を隔てて前後方向に延びる左右一対の縦フレーム54と、左右一対の縦フレーム同士を連結する複数の横フレーム57とを有する。エンジンフレームの各縦フレームは、左右一対の主フレーム間の内側に配置されている。各縦フレームの前端部は旋回フレームの横部材に、各縦フレームの後端部は旋回フレームの後端フレームにそれぞれ取り付けられている。【選択図】図3
