The paper presents slewing port cra11es with a luffing jib.The advantages of slewing port jib cranes are high lifting capacities,high speeds of re-loading and excellent mobility since theyare capable of load lifting, travelling, luffing and slewing. Thepaper gives a detailed description of their characteristics suchas the highest reached load-canying capacities, speeds of motionand accelerations. It also presents the crane assembly,driving mechanisms, loads and load cases, transport by shipsand testing of lifting capacity. As a practical example the paperpresents the slewing port jib crane with the capacity of25!15!5 tat a 27/37/40 m radius made by the Slovenian companyMetalna Maribor for the shipyard 3.
