Abstract:
1. A marine load raising and lowering system for use on a vessel, said system comprising: a first winch comprising a first driving mechanism configured to raise or lower a first cable from the first winch; a second winch comprising a second driving mechanism configured to raise or lower a second cable from the second winch; an operating mechanism connected to the first and second driving mechanisms of respectively the first and second winches and configured to synchronize the first and second driving mechanisms so as to perform synchronous raising or lowering of the first and second cable; and a load connector, configured to couple a load directly thereto, wherein the first and second cable are respectively connected to the load connector with a respective terminal end, wherein the system further comprises a first tension equalizing mechanism adapted to equalize the tension in the first and second cables, said first tension equalizing mechanism having a first cable-engaging member engaging with the first cable, and a second cable-engaging member engaging with the second cable wherein the first cable-engaging member and the second cable-engaging member are interconnected with each other while the first cable and the second cable are not interconnected with each other via the first tension equalizing mechanism, and the first cable-engaging member and the second cable-engaging member are moveable relative to a first reference structure to be mounted on the vessel, and wherein said first tension equalizing mechanism is configured to move the first and second cable-engaging members under the effect of a difference in tension in the first and second cable so as to equalize said tensions.
