Abstract
The use time till a display unit including an hour meter (a time measuring device) is replaced can be continued even if the time measuring device fails, and false alteration after shipping can be prevented while infallibly resetting the hour meter to zero when the vehicle equipped with the hour meter is shipped from the factory. The cargo handling vehicle includes a first storage device for accumulatively storing the vehicle use time measured by a first time measuring device provided in a display unit of the vehicle and a second storage device for accumulatively storing the vehicle use time measured by a second time measuring device provided in a control device. The control device allows the first and second storage devices to communicate the accumulated use times stored therein when the electric power of the vehicle is turned on. The control device compares the accumulated use times and writes the longer accumulated use time in the storage device storing the shorter one.
