Abstract
The present invention enables a reliable radio communication between a plurality of dump trucks and loaders, improves operability, and can flexibly cope with movement of the dump truck during the loading operation. To this end, a loader selecting means (2) is provided for each dump truck, and a plurality of channels are provided for each dump truck controller (6) and each loader controller (35), the dump truck controller (6) inputs a loader selection signal from the loader selecting means (2), and selects, from a plurality of channels, a channel available for communicating with the loader controller (35) corresponding to the loader selection signal to transmit a load weight value, and the selected loader controller (35) receives the load weight value on the channel available for communications, and displays the received load weight value on a weight display means (32).
