Abstract: An electrically driven industrial vehicle comprising a revolving body (11) attached to a undercarriage (7) so as to be able to turn horizontally; a power shovel device (20) for receiving a hydraulic drive force and operating, the power shovel device being mounted on the revolving body (11); and a hydraulic drive force generating unit provided to the revolving body (11), for generating hydraulic drive force for operating the power shovel device (20). The hydraulic drive force generating unit has a hydraulic fluid tank (73) for storing hydraulic fluid; a hydraulic pump (14) for feeding the hydraulic fluid in the hydraulic fluid tank to the power shovel device (20); an electric motor (13) for driving the hydraulic pump; and a lithium ion battery (50) for feeding electrical drive power to the electric motor.

Abstract: 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).

Abstract: The crawler belt 20 is structured of a plurality of inner shoes 21; a plurality of outer shoes 30 arranged to oppose each of the inner shoes; an endless ring-shaped rubber belt member 26 retained between the inner shoes and outer shoes respectively opposing each other; and an endless ring-shaped steel wire 27 embedded in the belt member extending in the longitudinal direction. The inner shoes 21 are arranged side by side along the inner periphery of the belt member, the outer shoes are arranged side by side along the outer periphery of the belt member, and concave portions are arranged in the longitudinal direction between the inner shoes and formed openly toward the inner periphery for receiving the sprocket teeth. Thereby, it is possible to reduce the travel noise while maintaining the advantages of the strength, durability and repairability of steel crawler belts.
