起重船
摘要：
本发明涉及包括旋转起重机(20；120)的起重船(1；100)以及使用这种船的方法。起重机包括悬臂(24，124)、主起重装置和副起重装置以升起和降低负载。主起重装置包括主起重索具(3，130)，主起重索具具有连接到起重机的悬臂的主起重机上滑车(38，138)并具有主起重机下滑车(39，139)。船包括悬臂支架(10，110)以在起重机不工作时支撑悬臂。根据本发明，主起重机下滑车由滑轮组(163)和负载附接组件(133)组装，所述滑轮组包括主起重机下滑车的滑车轮(132)，所述负载附接组件包括下部配重(137)和主负载附接装置(34，134)。起重船具有负载附接组件储存装置(10，150)以储存拆卸的负载附接组件，并且起重船还具有移位装置(167)，所述移位装置能够在负载附接组件组装到滑轮组时且当悬臂由悬臂支架支撑时接合及移动负载附接组件。
摘要（英）：

This invention relates to a crane vessel (1, 100) comprising a revolving hoist crane (20, 120) and a method of using such a vessel. The hoist crane comprises a jib (24, 124), main hoisting means and auxiliary hoisting means for raising and lowering a load. The main hoisting means comprise a main hoisting tackle (3, 130) with a main hoist upper block (38, 138) connected to the jib of the hoist crane and a main hoist lower block(39, 139). The vessel comprises a jib rest (10, 110) for supporting the jib when the crane is not in operation. According to the invention the main hoist lower block is assembled from a sheave block (163) comprising the sheaves (132) of the main hoist lower block and a load attachment assembly (133) comprising the lowering weight (137) and the main load attachment device (34, 134). The crane vessel is provided with a load attachment assembly storage device (10, 150) for storage of the disassembled load attachment assembly and displacement means (167) capable of engaging with and displacing the load attachment assembly while it is assembled to the sheave block and when the jib is supported by the jib rest.
