SHIP TO SHORE CRANE WITH DUAL TROLLEYS

摘要

A ship to shore crane (1) comprises a gantry structure (6), a cantilever crane girder (7) supported by the gantry structure, a water side trolley (23) supported by the crane girder and displaceable along a water side trajectory, a land side trolley (28) supported with respect to the gantry structure and displaceable along a land side trajectory, and a container landing platform (27) interposed between said trajectories. The water side trolley (28) is displaceable over said water side trajectory for transferring a container between the ship (3) and the landing platform (27) and the land side trolley (28) is displaceable over said land side trajectory for transferring a container between the shore (2) and the landing platform (27). The trolleys (23, 28) each are provided with respective hoisting means (31) and a respective spreader (32) carried by said hoisting means. For performing a rotation of a container (5) with respect to the vertical, slewing means (33) are provided which are supported by either the land side trolley (28) or the landing platform (27).
