METHOD FOR CONTROLLING PORT LOADING AND UNLOADING APPARATUS AND PORT LOADING AND UNLOADING APPARATUS

摘要

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. Thereby, the quay crane can reduce electric power to be consumed by the auxiliary equipment (20) which is the equipment other than the main equipment (10a) for perform the main operations such as the winding-up/down of a hoisting gear, and the traversing of a trolley.
