<p>The present invention relates to a crane capable of maintaining the balance regardless of agitation to a ship by using the concept of zero moment, and to the ship capable of loading and unloading goods on sea, which is far away from land, by being mounted with the crane. The invention provides the crane and the ship mounted with the same, comprising: an upper body which includes a horizontal structure in which a trolley is installed to transfer in the horizontal direction; a lower body which supports the upper body by being connected with a supporting joint at a spot in which the moment of the upper body becomes zero; and a supplementary support which is installed on the lower body, and is vertically adjustable in height to support the horizontal structure on one end in the horizontal direction of the horizontal structure. Thus, since the invention maintains the balance through the support by a zero moment point without applying strong power to a hydraulic cylinder, the invention can perform a precise balance controlling function.</p> |
