<p>The present invention relates to a hoisting crane (20) comprising a substantially hollow vertical column (21), a jib (24) and topping means for pivoting the jib up and down, comprising a jib winch (30) and a jib hoisting cable (31). The crane further comprises hoisting means (35) for hoisting a load, comprising a hoisting winch (35) and an associated hoisting cable (36), the hoisting winch being disposed in the column (21), so that the hoisting cable (36) extends from the winch (35) through the hollow vertical column (21). The jib winch (30) and the hoisting winch (35) are arranged on a rotatable winch support (50), which is rotatable about a rotation axis substantially parallel with the vertical column (21), such that the winch support is mounted movable with respect to the vertical column (21). The hoisting crane further comprises a deep water winch (82) positioned below the movable winch support (50) and an associated deep water cable (81) for raising and lowering a load extending through the rotation axis of the movable winch support, so that the deep water cable (81) extends from the deep water winch (82) through the hollow vertical column (21). The present invention further relates to a vessel provided with such a crane.</p> |
