The invention provides an offshore portal crane, and relates to the technical field of cranes, and the offshore portal crane comprises a main beam, two supporting legs, an electric winch module, two main hooks and two ground beams; the top ends of the two supporting legs are fixedly connected to the two ends of the main beam respectively, the bottom ends of the two supporting legs are fixedly connected to the two ground beams respectively, the supporting legs are perpendicular to the ground beams, the ground beams are in a long strip shape, and the linear direction of the ground beams is perpendicular to the linear direction of the main beam. The electric winch module is connected to the main beam; the two main hooks are connected with the electric winch module through steel wire ropes, and the electric winch module retracts and releases the steel wire ropes to drive one of the main hooks to ascend or descend or drive the two main hooks to ascend or descend synchronously. The steel wire rope gathering phenomenon is avoided, the height deviation of the two main hooks is adjusted, and rapid and stable offshore hoisting operation is achieved.
本申请提供一种海上门式起重机,涉及起重机技术领域,海上门式起重机包括:主梁、两个支腿、电动绞车模块、两个主钩和两个地梁;两个支腿的顶端分别固定连接在主梁的两端,两个支腿的底端分别固定连接在两个地梁上,支腿垂直于地梁,地梁为长条状,地梁所在直线方向与主梁所在直线方向垂直;电动绞车模块连接在主梁上;两个主钩均通过钢丝绳与电动绞车模块连接,电动绞车模块收放钢丝绳带动其中一个主钩升降或带动两个主钩同步升降。本申请避免钢丝绳扎堆现象,调节两个主钩的高度偏差,实现海上快速平稳吊装作业。
