Zusammenfassung: | To enable easy assembly of a hydraulic pump on a support part.SOLUTION: A turning work machine includes a swivel, a battery unit, an electric motor for rotating a drive shaft using electric power the battery unit outputs, the hydraulic pump having an input shaft to which motive power is input from the drive shaft, and adapted to be driven by the motive power input from the drive shaft to the input shaft to discharge working oil, the support part supporting the electric motor and the hydraulic pump on the swivel, and a bracket separate from the hydraulic pump and connecting the hydraulic pump and the support part. A structure having the bracket mounted to the hydraulic pump is mounted to the support part via the bracket.SELECTED DRAWING: Figure 19
【課題】油圧ポンプを支持部に容易に組み付けできる。【解決手段】旋回作業機は、旋回台と、バッテリユニットと、バッテリユニットが出力した電力によって、駆動軸を回転させる電動モータと、駆動軸から動力が入力される入力軸を有し、且つ駆動軸から入力軸に入力される動力によって駆動されて作動油を吐出する油圧ポンプと、電動モータ及び油圧ポンプを旋回台上に支持する支持部と、油圧ポンプとは別体であって、且つ油圧ポンプと支持部とを連結するブラケットと、を備え、油圧ポンプにブラケットが取り付けられた構造体が、ブラケットを介して支持部に取り付けられている。【選択図】図19 |
