摘要： One three-phase transformer (71A) 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 (71B) 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 (4) of a crane apparatus (10) stores DC power supplied from a three-phase full-wave rectifier (1) to a common bus (B), and supplies the stored power to the common bus (B) upon reduction of the DC power.

摘要： A three-phase full-wave rectifier (21) performs full-wave rectification of three-phase AC power (11A) supplied from ground power supply equipment, and supplies obtained DC power (12A) to a common bus (B). A Δ-Y connection type three-phase transformer (2) outputs three-phase AC power (11B) of a voltage phase shifted by π/6 from the three-phase AC power (11A). A three-phase full-wave rectifier (22) performs full-wave rectification of the three-phase AC power (11B) output from the three-phase transformer (2), and supplies obtained DC power (12B) to the common bus (B).

摘要： Provided is a quay crane which includes a seismic isolation device formed from laminated rubber, and which is capable of withstanding a large-scale earthquake. Particularly, provided is a quay crane including a seismic isolation device with a slide length of 1000 mm or over. In a quay crane including a seismic isolation device, the seismic isolation device includes: laminated rubber formed by laminating a steel plate and a rubber material; and an auxiliary support mechanism. The auxiliary support mechanism includes: a supporting body fixed to one of a top plate side and a bottom plate side of the seismic isolation device; and a contacting plate fixed to the other thereof. The supporting body and the contacting plate constituting the auxiliary support mechanism come into contact with each other at least in the event of an earthquake, and the auxiliary support mechanism supports a weight of the quay crane.
