Abstract: A hydraulic excavator is provided with an electric motor, an electrical equipment, a cooling fan, a partitioning member, and a cooling unit. The electrical equipment is connected electrically to the electric motor. The cooling fan generates cooling air. The partitioning member forms a ventilation path for guiding the cooling air. The cooling unit is arranged so as to block the ventilation path. The cooling unit has first and second cooling devices. The first cooling device cools a cooling medium for the electrical equipment. The second cooling device is arranged laterally to the first cooling device.

Abstract: A hydraulic excavator is provided, facilitating access to the lower side inside an engine compartment, allowing a maintenance job to be performed in a reasonable posture. The hydraulic excavator includes a revolving frame, an engine arranged on the revolving frame, and a counterweight arranged on the revolving frame, at the back side of the engine. A recess indented from the bottom face in the upward direction is formed at the counterweight. An opening is formed at the revolving frame for allowing a person to access from the lower side of the revolving frame to the space between the engine and the counterweight. The recess has a section overlapping with the opening, when viewed from the top.
