HOISTING CRANE AND OFFSHORE VESSEL

摘要

A hoisting crane (20) has a substantially hollow vertical column (21) with a foot (22) fixed to a support, and with a top (23). The hoisting crane has a jib (24) with an associated annular bearing structure (25) around the vertical column (21) and a jib connection member, so that the jib connection member can rotate about the column, and the jib can be pivoted up and down. The crane has a winch (35) and an associated hoisting cable (36) for hoisting a load. The winch is disposed in the foot of the vertical column, so that the hoisting cable passes through the hollow vertical column. A hoisting crane has a substantially hollow vertical column to the top cable guide (40) and than to the hoisting cable guide (43) on the jib. The winch is arranged on a support (50), which is mounted movably with respect to the vertical column.
