随着造船业大型化的发展,分段越来越大,越来越重,老式的门座式起重机由于受到倾覆力矩的限制,逐渐不能满足现代造船业的发展。造船门式起重机由于其起重量大,能靠上下小车完成分段翻身等优势,逐渐成为各大船厂发展的首选设备。1起升同步的重要性造船门式起重机主要用于造船平台上大分段的吊装和对位。大分段由于体积巨大,往往需要多吊点起吊,因此,造船门式起重机常用工况为抬吊工况。
With the development of large-scale shipbuilding industry, the segment is more and more large and heavier. Due to the limitation of overturning moment, the old portal crane can not meet the demand of modern shipbuilding industry gradually. Because of its heavy lifting capacity, the ship-building gantry crane can realize the advantages of turning over sections by turning the car up and down and gradually become the preferred equipment for the development of major shipyards. The importance of a lifting synchronization Shipyard gantry crane is mainly used for large sections of the shipbuilding platform lifting and alignment. Large segments due to the huge size, often need to lift more lifting point, therefore, shipbuilding gantry crane for lifting conditions.
