To provide a revolving frame of a work machine and a method of assembling the revolving frame of a work machine, which are separable into at least two components, provided in front and rear, and which can easily perform the connecting work of the two components.SOLUTION: A revolving frame 120 is separable into a front frame 121 and a rear frame 122. A contacting portion 743A of a positioning block 743 contacts a rotation block 732 at the position where a front hole 73A and a rear hole 74A match each other when a pin fitting portion 742 of the rear frame 122 is fitted to a positioning pin 731 of the front frame 121 and the rear frame 122 is rotated downward. As a result, the connecting pin can be easily inserted into the front hole 73A and the rear hole 74A.SELECTED DRAWING: Figure 4

    【課題】少なくとも前後2つの部材に分離可能とされ当該2つの部材の連結作業を容易に行うことが可能な作業機械の旋回フレームおよび作業機械の旋回フレームの組立方法を提供する。【解決手段】旋回フレーム120は、前フレーム121と後フレーム122とに分離可能とされる。後フレーム122のピン嵌合部742を前フレーム121の位置決めピン731に嵌合させ、後フレーム122を下方に回動させると、前孔部73Aと後孔部74Aとが互いに合致する位置で、位置決めブロック743の当接部743Aが回動阻止部732に当接する。この結果、連結ピンを前孔部73Aおよび後孔部74Aに容易に挿入することができる。【選択図】図4
