<p><P>PROBLEM TO BE SOLVED: To effectively arrange a battery mounted on a turntable of a service vehicle in a good weight balance. <P>SOLUTION: The service vehicle 1 has the turntable 11, a boom 25 or the like, a driving force generation part, and a battery storage part 12. The turntable 11 is mounted on a travelling device 5, and the boom 25 or the like is attached to the front of the turntable 11. Then the driving force generation part is provided in the turntable 11, and the battery storage part 12 stores a battery consisting of a high-capacity secondary battery. The driving force generation part has a hydraulic pump 14, an electric motor 13, an operating fluid tank 73, and an oil cooler 71. The hydraulic pump 14 supplies hydraulic pressure used for operating the boom 25 or the like, and the electric motor 13 drives the hydraulic pump 14. The operating fluid tank 73 stores the operating fluid, and the oil cooler 71 cools the operating fluid. Then the driving force generation part is arranged below the battery storage part. The hydraulic pump 14, the electric motor 13, and the oil cooler 71 are arranged under a lower cover so that they are covered with the lower cover which is located in the position of the interior of the turntable 11 lower than the battery storage part 12. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
