PROBLEM TO BE SOLVED: To provide an electrically-driven work machine that does not require prior installation of a power cable on a ceiling of a factory or the like, does not cause twisting or the like of the power cable during turning operation or the like, and does not allow the power cable to interfere with a vehicle body.SOLUTION: An electrically-driven work machine includes a lower machinery 2 and an upper turning body 15 installed rotatably above the lower machinery 2, and provided with an electric motor that serves as a driving source. A power collector 30 is installed between the upper turning body 15 and the lower machinery 2, for leading a power source supplied from the lower machinery side to the upper turning body side. A cable support device 60 is installed on a side part of the lower machinery 2, for supporting a cable 1 on a power source side connected to an external power source and supplying the power source to the lower machinery side.
【課題】工場の天井等に予め電源ケーブルを架設する必要がなく、また、旋回動作等を行う際に電源ケーブルにねじれ等が生じることがなく、また電源ケーブルが車体に干渉するおそれのない電動式作業機械の提供。【解決手段】下部走行体２と、この下部走行体２の上方に旋回可能に配置され、駆動源となる電動機を備えた上部旋回体１５とを有し、上部旋回体１５と下部走行体２との間には、下部走行体側から供給された電源を上部旋回体側に導く集電装置３０を設け、下部走行体２の側部には、外部電源に接続されて、下部走行体側に電源を供給する電源側ケーブル１を支持するケーブル支持装置６０を設ける。【選択図】 図１
