The invention provides offshore hoisting equipment, and belongs to the technical field of hoisting equipment. The offshore lifting equipment comprises a supporting seat, a stand column and a lifting arm used for lifting an object, at least one rotation point is arranged from the supporting seat to the tail end of the lifting arm, and the at least one rotation point is in running fit through a tapered roller bearing. The offshore hoisting equipment can effectively solve the technical problem that in the prior art, when hoisting equipment is used under the deflection working condition, friction between the inner ring and the outer ring of the bearing is increased, and consequently a rotation device loses efficacy.
本发明提供一种海上用起吊设备,属于起吊设备技术领域。该海上用起吊设备包括支撑座、立柱和用于起吊物体的吊臂,支撑座至吊臂的末端至少设有一个回转点,至少一个回转点处通过圆锥滚子轴承转动配合。本发明提供的海上用起吊设备可以有效解决现有技术中起吊设备在偏摆工况下使用时因轴承的内外圈摩擦增大而导致回转装置失效的技术问题。
