<p>PROBLEM TO BE SOLVED: To eliminate time required for charging batteries and increasing efficiency of a manual-operation truck by supplying AC power supply from the facilities side to the manual-operation truck side in a power supply device, driving a drive means by being connected to a facilities-side power supply means formed on the manual-operation truck, and reducing the weight of the manual-operation truck. SOLUTION: An AC power supply applied from a power application part 160 is connected to a power supply transformer and a power supply device 166 containing a rectification part. One of a power supply output terminal of the power supply device 166 is connected to a first electric motor 140 and a second electric motor, and the other power supply output terminal is connected to a motor drive part 170 and a control unit 180 generating a control signal to the motor drive part 170. Casters 105 for moving a manual-operation truck in an arbitrary direction are formed on the bottom face of a main body 110. This constitution can eliminate any necessity of a time for charging caused by conventional inner energy exhaustion of batteries, reduce the weight, and improve efficiency of the manual-operation truck.</p> |
