To utilize a merit of suppressing a rear end turning radius that a cable holding member does not protrude behind a rear end of a revolving structure even if the rear end turning radius is suppressed.SOLUTION: In an electric driven hydraulic shovel, a cable holding member 55 is configured such that a first opening of a cable insertion path formed in an upwardly convex arcuate shape is opened on a rear end side of a revolving structure with respect to a shaft 53, and a second opening is opened on the opposite side of the first opening across the shaft 53. A cable extending from an external power source is configured to be passed through the cable insertion path from the rear end side of the revolving structure through the first opening, taken out from the second opening to the front side of the shaft, and connected to a control panel.SELECTED DRAWING: Figure 5
【課題】後端旋回半径を抑えても旋回体の後端よりも後方にケーブル保持部材が突出せず、後端旋回半径を抑えるメリットを活かす。【解決手段】電気駆動式油圧ショベルにおいて、上方に向かって凸の弓形に形成されたケーブル挿通路の第１の開口が軸５３に対して旋回体の後端側で開口し、第２の開口が軸５３を挟んで第１の開口と反対側で開口するようにケーブル保持部材５５を構成し、外部電源から延びるケーブルが、旋回体の後端側から第１の開口を介してケーブル挿通路に通され、第２の開口から軸よりも前方側に取り出されて制御盤に接続されるように構成する。【選択図】図５
