Electrically driven industrial vehicle
摘要：
A shovel loader (1) has a vehicle body frame (9), a travel device (5), a loader device (20), and a drive power generation section for generating drive power for making the travel device (5) travel. The vehicle body frame (9) has a pair of side frames (9a, 9a) arranged on both the left and right sides of the shovel loader (1). The loader device (20) is made up of a pair of lift arms (21,21) vertically swingably attached to the pair of side frames (9a, 9a) and of a bucket (29) vertically swingably attached to the forward end of the pair of lift arms (21,21). The drive power generation section has a pair of electric motors (71,71) for individually transmitting drive power to the pair of travel devices (5,5) and capable of being controlled independent of each other so that a vehicle (10) can be made to travel in a manner the left and right are independent of each other, and also has a battery (50) for supplying electric power to the electric motors (71,71).
摘要（中）：

铲装置（1）具有车身框架（9），行走装置（5），装载装置（20）和用于产生用于使行进装置（5）行进的驱动力的驱动力发电部。 车身框架（9）具有布置在铲式装载机（1）的左右两侧的一对侧框架（9a，9a）。 装载装置（20）由一对提升臂（21,21）构成，该提升臂垂直地可摆动地安装在一对侧框架（9a，9a）上，一对铲斗（29）垂直地可摆动地附接到 一对提升臂（21,21）。 驱动发电部具有一对电动机（71,71），用于将驱动力单独地传递给一对行驶装置（5,5），并能够彼此独立地进行控制，使得车辆（10）能够 使得左右移动彼此独立，并且还具有用于向电动机（71,71）供电的电池（50）。
