Abstract

See full text

An excavator includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, actuators configured to drive driven portions including the lower traveling body and the upper turning body, a power storage mounted on the upper turning body and used as an energy source for driving the actuators, a cooling circuit configured to cool the power storage, and a fan mounted on the upper turning body and configured to blow air to a radiator and a condenser for cooling the radiator and the condenser. Further, the power storage is arranged such that the power storage is apart from a path in which air outside the upper turning body, by an operation of the fan, is introduced into inside the upper turning body, passes across the heat exchanging device, and is discharged to the outside of the upper turning body.
