摘要:
A haulage vehicle includes a body, a load measurement device that measures a mounted load value of the body, a traveling electric motor, and a travel control device that outputs an electric motor command value, the travel control device sets a backward movement limiting set value to ON when it is determined that the haulage vehicle is in execution of either loading work or dumping work, and sets the backward movement limiting set value to OFF when a forward position signal and an accelerator pedal command value are inputted, an electric motor command value formed of a backward movement limiting command value is outputted to the traveling electric motor when the backward movement limiting set value is ON, and an electric motor command value formed of a normal command value is outputted to the traveling electric motor when the backward movement limiting set value is OFF.
