An upper rotating body (3) of an electric hydraulic shovel (1) is provided with: an electric motor (13) serving as a power source; a battery (15) for storing power supplied to the electric motor (13); a power supply port (16) to which a power supply cable (17) for supplying power to the electric motor (13) or the battery (15) is connected via a relay cable (18); and a camera (23) that monitors (captures) the surroundings of the lower traveling body (2) and the upper revolving body (3). The camera (23) is attached to the upper rotating body (3) at a position higher than the power supply port (16), and captures an image of the power supply port (16). As a result, it is possible to confirm, by means of the monitor (10), the connection status of the power supply port (16) and the relay cable (18) with respect to the power supply port (16), the depression or entrainment of the power supply cable (17) during operation of the electric hydraulic shovel (1), and the like.
电动式液压挖掘机(1)的上部回转体(3)具备:成为动力源的电动马达(13);电池(15),其储存向电动马达(13)供给的电力;供电口(16),其经由中继线缆(18)连接用于向电动马达(13)或电池(15)供给电力的供电线缆(17);以及照相机(23),其监视(拍摄)下部行驶体(2)以及上部回转体(3)的周围。照相机(23)在比供电口(16)高的位置安装于上部回转体(3),拍摄供电口(16)。由此,能够通过监视器(10)确认供电口(16)、中继线缆(18)相对于供电口(16)的连接状况、电动式液压挖掘机(1)运转时的供电线缆(17)的踩踏、卷入等。
