The invention belongs to the technical field of ships, and discloses a ship crane and a ship. The marine crane comprises a crane body, a switching limiting structure and a base. The switching limiting structure comprises a switching cylinder and a limiting piece. The crane body is fixedly connected to the transfer cylinder, and the rotation limiting part of the transfer cylinder is rotationally inserted into the base and partially supported on the supporting part of the base. One of the rotating limiting part and the supporting part is provided with an arc-shaped limiting hole extending in the circumferential direction of the transfer cylinder; and the other one is provided with a plurality of through holes which are distributed at intervals along the circumferential direction of the transfer cylinder. The limiting piece can penetrate through the arc-shaped limiting hole and any through hole and is partially in lap joint with the rotating limiting part. Structures such as equipment or protective barriers in a non-hoisting working area can be effectively prevented from being impacted, and the working performance and the use safety of the marine crane are effectively improved.
本发明属于船舶技术领域,公开了船用吊机及船舶。其中,船用吊机包括吊机本体、转接限位结构和底座。转接限位结构包括转接筒和限位件。吊机本体固定连接于转接筒,转接筒的转动限位部转动插接于底座且部分支撑于底座的支撑部。转动限位部和支撑部中的一个设有沿转接筒的周向延伸弧形限位孔;另一个设有多个沿转接筒的周向间隔分布的通孔。限位件能穿过弧形限位孔和任一通孔,并部分搭接于转动限位部之上。能够有效避免撞击非吊装工作区域的设备或防护栏杆等结构,有效提升了船用吊机的工作性能和使用安全性。
