Level Luffing Jib Type Deck Crane

Abstract

Burtoning method by cargo winches is still adopted to a large extent for ship cargo handling duty. However, ship deck crane is now getting into the lime-light as one of the measures to promote efficiency and simplicity in cargo handling. In 1961 the jib type deck cranes of Kampnagel make were installed, for the first time, on three export sister-ships to USSR built at Hitachi Sakurajima Shipyard. And we are fully assured of advantages of the cranes under practical operations. This report refers to a brief introduction to the mechanism, to advantages of the cranes compared with cargo winches and to some dynamical analysis on it.
