Abstract (en)
A hoisting crane used on ships to load mixed cargo and containers into the holds and to unload them from the holds comprises a crane housing (1) which can be slewed on a rotary slewing ring (4), a jib (3) hingedly connected to the bottom part of said crane housing (1), luffing means in order to luff the jib (3) in and out, a hoisting drum (8) with drive motor fitted in or on the housing (1), and a hoisting cable (6) which is to be wound on or off the hoisting drum (8) and which runs over guide means (7) at the top side of the crane housing (1) and guide means (8) at the free end of the jib (3). In order to enable the jib (3) in the fully luffed-in position to take a vertical position, the jib (3) is designed as a lattice which is U-shaped in cross section, and which accommodates a part of the crane housing (1) in the fully luffed-in position, while the luffing means comprise at least one tension cylinder (10).
