Abstract
(EN)
An electrically-driven service vehicle comprising a turning body (11) attached to a traveling carriage (7) so as to be horizontally turnable, a power shovel device (20) mounted on the turning body (11) to operate on receiving a hydraulic drive force, and a hydraulic drive force generating unit provided on the turning body (11), for generating a hydraulic drive force to operate the power shovel device (20). The hydraulic drive force generating unit comprises a hydraulic oil tank (73) storing hydraulic oil, a hydraulic pump (14) supplying hydraulic oil in the hydraulic oil tank to the power shovel device (20), an electric motor (13) driving the hydraulic pump, and a lithium ion battery (50) supplying drive electric power to the electric motor.
