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).
