摘要：This paper describes an innovative system of container reloading. The system involves Tandem spreaders included in portal cranes moving at the quay edge of maritime port container terminals. Thanks to the modern construction, it is possible to reload up to four ISO 1C containers at the same time, which not only reduces the reloading time, but also increases the reloading capacity of the terminal. The paper also discusses the economic aspects of the introduction of these new spreaders.
