The invention refers to a four-chains paternoster cargo handling system, being kind of cargo lifting and continuously transferring working facility. It is composed of four-chains paternoster drive, of one or more movable cargo handling/transferring platforms, of at least one stationary platform receiving cargo and of at least one stationary platform delivering cargo. All platforms are fitted with cargo supports, very often forks, which could be equipped with cargo transfer devices, active conveyors or passive rotating elements. Design and disposition of cargo supports on any pair of one stationary and one movable platform is complementary and enables, when these platforms are by-passing each other, full penetration of their supports so that they can deliver a cargo to each other. Each movable platform respectively each cantilever beam, fitted on each platform side, is suspended on two paternoster chains, and thanks to the arrangement of chains and their chain wheels makes transiting of cantilever beams, between chains and wheels, possible.
