Summary:To provide an electric construction machine which improves safety during maintenance.SOLUTION: An electric construction machine is provided with: a base plate; high voltage devices placed on the base plate and including an inverter to which power is supplied from a power source and an electric motor driven with the power inverted by the inverter; non-high voltage devices which are placed on an area other than an area where the high voltage devices are placed, on the base plate, and which include a hydraulic pump driven by the electric motor, a hydraulic valve delivering hydraulic oil discharged by the hydraulic pump, and a cooling unit cooling various devices; an exterior cover comprising a high voltage device cover openably/closably covering the area provided with the high voltage devices on the base plate and non-high voltage device covers openably/closably covering the area provided with the non-high voltage devices on the base plate; and inside the exterior cover, a partition part partitioning the high voltage area in which the high voltage devices on the base plate are arranged from the non-high voltage area in which the non-high voltage devices on the base plate are arranged.SELECTED DRAWING: Figure 2 【課題】メンテナンス時の安全性を向上させる。【解決手段】ベースプレートと、該ベースプレート上に設けられ、電源からの電力が供給されるインバータ及び該インバータが変換した電力によって駆動される電動モータを含む高電圧機器と、ベースプレート上の高電圧機器とは異なる領域に設けられて、電動モータによって駆動される油圧ポンプ、該油圧ポンプが吐出する作動油を分配する油圧バルブ、及び、各種機器を冷却するクーリングユニットを含む非高電圧機器と、ベースプレート上の高電圧機器が設けられた領域を開閉可能に覆う高電圧機器カバー、及び、ベースプレート上の非高電圧機器が設けられた領域を開閉可能に覆う非高電圧機器カバーを有する外装カバーと、外装カバーの内側で、ベースプレート上の高電圧機器が設けられた高電圧領域とベースプレート上の非高電圧機器が設けられた非高電圧領域とを区画する仕切り部と、を備える。【選択図】図２
