Abstract
The present invention makes it possible to, in a configuration provided with electrical components such as an inverter device for controlling an electric motor, obtain a high degree of freedom with regard to the layout of the electrical components and efficiently place the electrical components in a limited space. An excavator comprises: an electric motor; a hydraulic fluid tank in which hydraulic fluid is stored; a hydraulic pump that is driven by the electric motor and supplies the hydraulic fluid within the hydraulic fluid tank to an actuator; and an inverter device that, with respect to the hydraulic fluid tank, is provided at a position away from a left-side surface part of the hydraulic fluid tank.
Claims8
A construction machine comprising:
- a hydraulic oil tank that tanks a hydraulic oil, wherein the hydraulic oil tank is placed on one side of a swing frame in a right-left direction;
- a battery unit that supplies power to an electric motor, wherein the battery unit is placed on another side of the swing frame in the right-left direction relative to the hydraulic oil tank;
- a hydraulic pump driven by the electric motor thereby to supply the hydraulic oil in the hydraulic oil tank to an actuator;
- and
- an electric device provided for the hydraulic oil tank, the electric device being provided in a position spaced apart from a side face of the hydraulic oil tank and wherein the electric device is located in front of the battery unit and to a side of the battery unit facing the hydraulic tank.
A construction machine comprising:
- a prime mover;
- a hydraulic oil tank that tanks a hydraulic oil;
- a hydraulic pump driven by the prime mover thereby to supply the hydraulic oil in the hydraulic oil tank to an actuator;
- an electric device provided for the hydraulic oil tank, the electric device being provided in a position spaced apart from a side face of the hydraulic oil tank, wherein the electric device is provided in a state of being supported on a pedestal that supports the hydraulic oil tank, and wherein the pedestal forms a space part on a back side of a support face part that supports the hydraulic oil tank, and the construction machine comprises a second electric device provided in a state of being supported on the back side of the support face part.
