In the present invention, first three-phase AC power comprising voltage phases which are in phase with power-source power is outputted as operating power by a three-phase transformer (71A) which is one of two three-phase transformers making a pair among three-phase transformers provided for each power-supply line, second three-phase AC power, the voltage phases of which are out of phase by pai/6 with the power-source power, is outputted as operating power by a three-phase transformer (71B) which is the other of the two three-phase transformers making the pair and DC power supplied from a three-phase full-wave rectifier (1) to a common bus (B) is stored by a power storage device (4) of a crane apparatus (10) so that the stored power is supplied to the common bus (B) when the DC power declines.
