Abstract

The paper presents slewing port cranes with a luffing jib. The advantages of port jib cranes are high lifting capacities, high speeds of reloading 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, load cases and testings 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 company Metalna Maribor for the shipyard 3. maj, Rijeka, Croatia

Secondary title: Vrtljivi pristaniški žerjavi z nagibno ročico
Secondary abstract: V članku so predstavljeni vrtljivi pristaniški žerjavi z nagibno ročico. Odličnost vrtljivih pristaniških žerjavov se kaže predvsem v njihovih velikih nosilnostih in hitrostih pretovarjanja ter izredni gibljivosti, saj omogočajo dvigovanje bremen, vožnjo, nagibanje in vrtenje. V članku je podrobneje podan opis njihovih značilnosti kot so največje dosežene nosilnosti, hitrosti gibanja in pospeški. Prikazani so tudi sestava in pogonski mehanizmi žerjavov, delujoče obtežbe in obtežni primeri, ladijski transport in preizkus nosilnosti. Kot praktični primer smo predstavili vrtljivi pristaniški žerjav nosilnosti 25/15/5 t pri dosegu 27/37/40 m, ki ga je slovenska firma Metalna Maribor izdelala za ladjedelnico 3. Maj, Rijeka, Hrvatska.
