Abstract
One three-phase transformer (A) out of two paired three-phase transformers among three-phase transformers provided for respective feeder lines outputs, as operating power, first three-phase AC power of the same voltage phase as that of power-supply power. The other three-phase transformer (B) out of the two paired three-phase transformers outputs, as the operating power, second three-phase AC power of a voltage phase shifted by π/6 from that of the power-supply power. The power storage device () of a crane apparatus () stores DC power supplied from a three-phase full-wave rectifier () to a common bus (B), and supplies the stored power to the common bus (B) upon reduction of the DC power.
