PURPOSE: A power supply apparatus of the excavator using the electricity as the power source is provided to improve the reliability and the stability of the device by comprising a supporting frame to reinforce the stability. CONSTITUTION: A transmission tower(10) is mounted on the top of an excavator main body(10). A wire(9) is secured by a guide plate(19) and induced through a wire transfer tube(18). The wire transfer tube prevents the wire from being entangled since the wire is allowed to be twisted. A reinforcing support(15), a horizontal connection table(16), and a diagonal connection stick(17) are used in order to reinforce a transmission tower tube(14). |
