The invention relates to a six-chord boom for an offshore floating crane, a floating crane, a floating crane system and application of the six-chord boom. The six-chord boom (30) comprises a boom root part (301), a boom middle part (302) and a boom head part (303) which are connected in sequence; and the cantilever crane middle part (302) comprises six main chord members and web members for connecting the main chord members. The crane further comprises a rotary platform (31), a lifting hook (32), a steel wire rope winding mechanism (33), a driving mechanism (34) and a supporting barrel (35). The floating crane system further comprises an offshore floating body (1) and a shelf (2) used for placing a six-chord boom on the crane during sailing, and the system is applied to fishing, hoisting and overturning of large offshore components. Compared with the prior art, the load acting on the ship body can be reduced, and transverse turnover of the long component can be independently completed so as to meet the installation requirements of large offshore components and wind turbine generators.

    本发明涉及一种海上浮吊用六弦杆臂架、浮式起重机和浮吊系统及其应用,六弦杆臂架(30)包括依次连接的臂架根部(301)、臂架中部(302)和臂架头部(303);臂架中部(302)包括六根主弦杆以及将主弦杆进行连接的腹杆。起重机还包括回转平台(31)、吊钩(32)、钢丝绳缠绕机构(33)、驱动机构(34)及支撑筒体(35)。浮吊系统还包括海上漂浮体(1)、航行时用于放置起重机上六弦杆臂架的搁架(2),该系统应用于大型海上构件的打捞、吊装和翻转。与现有技术相比,本发明可降低作用在船体上的载荷,可独立完成长型构件的横向翻身,以适应大型海上构件及风电机组的安装需求。
