PROBLEM TO BE SOLVED: To provide an enough rotation stop support insertion space for an engine support erected in the vicinity of a transverse frame of a main frame of a swivel frame for a swivel work machine so as to allow an operator to access inside the support easily and ensure the rigidity of supports to install them securely.SOLUTION: An engine support 18a for a swivel frame 8 is erected by joining a pair of bent plates 20 and 22 having an L-shaped cross section to form a rectangular cylindrical shape, and on the upper edge of which, a support plate 24 having a bolthole for mounting an engine is joined. One side of the bent plate 20 is joined with a transverse frame 56, and the other side extends in parallel with an outer surface 52a of a main frame 52, one side of the bent plate 22 is joined with the outer surface 52a of the main frame 52, and further, the bent plate 20 is provided with an opening 21 that allows an operator to access from the outside to the inside of the rectangular cylindrical shape by the fingers.

    【課題】旋回作業機の旋回フレームの主フレームの横フレーム近くに立設されるエンジンサポートの回り止めサポート挿入スペースを十分にし、作業者のアクセスを容易にし、かつサポートの剛性を確保し強固に設置する。【解決手段】旋回フレーム8のエンジンサポート18aが、一対の断面L形の曲げ板20,22を矩形筒状に接合して立設され、上端部にエンジンを載置するボルト穴を有した支持板24が接合され、曲げ板20の一辺が横フレーム56に接合され、他辺が主フレーム52の外側面52aと平行に延び、曲げ板22の一辺が主フレーム52の外側面52aに接合され、さらに曲げ板20が、外方から矩形筒状の内側に作業者の手指によるアクセスを可能にした開口21を備えている。【選択図】図2
