The plant is mainly designed to increase the productivity of freight handling operations - for instance containers, in any kind of depot - to simplify the engineering works supporting the mobile crane (1) having a transversal boom (2), to eliminate stressing working conditions for the operator of the mobile crane (1) and to make essentially automatic the freight handling operations; said mobile crane (1) runs on a track (11) placed at the top of a fixed longitudinal frame (10) having stanchions (20) which transmit the loads to the ground at fixed positons constituted advantageously by foundation plinths (21) on piles (22); the cabin (12) is independent of the upper trolley (3) of the mobile crane (1); an intermediate trolley (13) receives the containers (7) from a shuttle trolley running longitudinally on a shelf (9) of said frame (10) and transfer them onto lorries (16) and trolleys (17, 162) of a conveyor ring (18, 154) of the depot assisted by bridge cranes; in maritime depots, the hold covers of ships may be stored on supporting elements (24) of said frame (10); the plant may be installed in newly builded or existing maritime, lake side, riverside, railway or terrestrial depots.
