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 working vehicle includes a revolving pump output calculating section that calculates the revolving pump output where the output of an electric motor is converted to be the output of a hydraulic pump. A reduction amount determining section determines a reduction amount for the output of the hydraulic pump during the multiple operations based on the revolving pump output. A pump output determining section determines a value, where the reduction amount is subtracted from the output of the hydraulic pump which is determined according to the state with the multiple operations, in a first control mode as the output of the hydraulic pump during the multiple operations. The pump output determining section increases the output of the hydraulic pump during the multiple operations in a second control mode more than in the first control mode.

Abstract: A structure for mounting a diesel oxidation catalyst device to a generator motor includes: a generator motor arranged between an engine and a hydraulic pump; a diesel oxidation catalyst device mounted on an upper part of the generator motor; and a bracket provided between the generator motor and the diesel oxidation catalyst device and adapted to separately arrange the diesel oxidation catalyst device above the generator motor, wherein a boss with screw hole erecting upward is formed on an upper part of a generator motor housing, and a lower part of the bracket is fastened to the boss with screw hole with a bolt.

Abstract: A structure for mounting a diesel oxidation catalyst device to a generator motor includes: a generator motor arranged between an engine and a hydraulic pump; a diesel oxidation catalyst device having an approximately cylindrical shape and mounted at an upper part of the generator motor; and a bracket provided between the generator motor and the diesel oxidation catalyst device and adapted to separately arrange the diesel oxidation catalyst device above the generator motor, wherein a cylinder center axis of the diesel oxidation catalyst device is within a width of a generator motor housing in a rotation center axis direction.
