The paper presents slewing port cranes with a luffing jib. The advantages of slewing port jib cranes are high lifting capacities, high speeds of re-loading and excellent mobility since they are capable of load lifting, travelling, luffing and slewing. The paper gives a detailed description of their characteristics such as the highest reached load-carrying capacities, speeds of motion and accelerations. It also presents the crane assembly, driving mechanisms, loads and load cases, transport by ships and testing of lifting capacity. As a practical example, the paper presents the slewing port jib crane with the capacity of 25/15/5 t at a 27/37/40 m radius made by the Slovenian companyMetalna Maribor for the shipyard 3. Maj, Rijeka, Croatia.
