PURPOSE: A damping joint device for a mobile-harbor lifting system is provided to enhance stability of a mobile harbor and lifting device since if strong vibration occurs, shock due to instantaneous overload decreases. CONSTITUTION: A damping joint device for a mobile-harbor lifting system comprises a foot support(110), a plurality of universal joint units(120) and a damping cylinder(130). The foot support is coupled to the upper end of a lifting device(60). The lifting device lifts a crane unit(40) from a mobile harbor. The universal joint units are aligned on the top of the foot support. The damping cylinder comprises a piston rod(131) and a cylinder body(132). The ends of the piston rod are respectively coupled to the universal joint units. The cylinder body is filled with working fluid. |
