ABSTRACT:
As earth and sand are loaded on a dump truck by operating a loader, a quantity of load to be carried by the dump truck is stepwise increased at every time when a loading operation is performed. To assure that the load does not substantially exceed a rated load given to the dump truck, there is a need of estimating a load to be carried by the dump truck during a next loading operation. To this end, there is provided an apparatus for representing a load to be carried by the dump truck for which representing is effected on the basis of the load which has been measured using a load meter of the type mounted on the dump truck. The apparatus includes a calculating unit for calculating the number of loading operations by addition at every time when the load is stepwise increased so as to allow a load to be carried by the dump truck during a next loading operation to be estimated with reference to the number of loading operations and the load which has been loaded on the dump truck till now and a display unit for representing an estimative load to be carried by the dump truck, the estimative load being calculated using the calculating unit.
