Electric excavator
The turning frame (20) turns around a turning center (CP). The battery (31) is supported by the rotating frame (20). The electric motor (33) is supported by the turning frame (20) and is supplied with power from the battery (31). The hydraulic pump (34) is supported by the turning frame (20), is driven by the electric motor (33), and is disposed closer to the turning center (CP) than the electric motor (33) in plan view.
回转框架(20)绕回转中心(CP)回转。电池(31)支承于回转框架(20)。电动马达(33)支承于回转框架(20)，从电池(31)被供给电力。液压泵(34)支承于回转框架(20)，且由电动马达(33)驱动，在俯视时配置于比电动马达(33)靠近回转中心(CP)的位置。
