PURPOSE:To enhance the efficiency of operations by a method in which turning angles of boom, etc., and inclined angles of a radio-driven working vehicle are detected, and the detection signals are displayed on a transmitter with an operator to notify exact working states to the operator. CONSTITUTION:A transmitter 12 to operate a back hoe on remote control basis is provided with a receiving block 45a and a display block 45b. Information detected by the bottom sensor of vehicle of working conditions, e.g., throttling amount, etc., of engine and presence or absence of operating the lever of the back hoe is received by the receiver 7 of the vehicle and displayed. On the other hand, the receiver 7 of the vehicle has a detection block 36a and a transmitting block 36b. Information of conditions of the vehicle is detected by each sensor and sent to the transmitter 12. The conditions of the vehicle can thus be displayed on the radio operator of the operator, and while knowing exact working conditions, the operations can be continued. |
