Abstract
An accumulated use time for cargo handling vehicles is accurately displayed by a time measuring device even if the time measuring device fails and is replaced. Units such as a display unit and a control unit of the cargo handling vehicle each include a time measuring device and a storage device. The device may perform in a synchronization mode in which the difference between the accumulated use times of both devices is made the same and a synchronization inhibition mode in which the accumulated use times are not changed. The accumulated use times are communicated between the function units, and the accumulated use time of the cargo handling vehicle and the absolute value of the difference between the accumulated use times of both measuring devices are taken into consideration. The appropriate mode is selected and the time measurement is carried out in the selected mode.
