The anode height measuring precision pole changing system is installed on the multifunctional crane of the electrolytic aluminum workshop. The system automatically measures the height of the residual pole in the tank, the height of the residual pole itself, the height of the new pole itself, and the height of the new pole should be placed in the tank. Instead of manually completing the replacement of the residual anode. Thus, it improves the precision of the polarity change, improves the safety production capacity, reduces the labor intensity, and realizes the automation and intelligence of the anode pole changing operation.
