Abstract: A quay crane including auxiliary equipment, which is equipment other than main equipment for performing main operations of the quay crane. The auxiliary equipment includes: a main equipment cooling device for cooling the main equipment; a loading and unloading lighting device for lighting a loading and unloading operation range of the main equipment; a room cooling device for cooling a room; and a room lighting device for lighting the room. If an operating condition of the main equipment or a room condition satisfies a predetermined electric power reduction condition while the quay crane is in operation, the auxiliary equipment that is keeping the operating condition of the main equipment or the room condition is put into a power saving mode in which the auxiliary equipment consumes less electric power than in a normal operation.

Abstract: 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.

Abstract: Provided is a quay crane including auxiliary equipment (20), which is equipment other than main equipment (10a) for performing main operations of the quay crane. The auxiliary equipment (20) includes: a main equipment cooling device for cooling the main equipment (10a); a loading and unloading lighting device for lighting a loading and unloading operation range of the main equipment (10a); a room cooling device for cooling a room; and a room lighting device for lighting the room. If an operating condition of the main equipment (10a) or a room condition satisfies a predetermined electric power reduction condition while the quay crane is in operation, the auxiliary equipment (20) that is keeping the operating condition of the main equipment (10a) or the room condition is put into a power saving mode in which the auxiliary equipment (20) consumes less electric power than in a normal operation.
