ONE-POINT MOORING DEVICE WITH WEIGHT

PURPOSE:To absorb a mooring force in up-and-down movement of a weight, by arranging a sliding board connected to a buoy slidable only longitudinally through a roller holding member fixed to a mooring float, and hooking a wire with one end fixed to the sliding board and the other end to the weight, to a pulley of the roller holding member. CONSTITUTION:At a connecting rod on a buoy which is fixed to the sea bed, a sliding board 9 is connected with a hinge through a turntable. The sliding board 9 is inserted in a roller holder 8 of a roller receiver 7 which is fixed to a mooring float 6, to be slidable freely. A weight 10 is linked to the sliding board 9 by a wire whose one end is fixed to the sliding board 9. When the mooring float 6 moves by an outer force such as waves, the energy is absorbed by the weight 10, together by the sliding movement between the roller receiver 7 and the sliding board 9, reducing the load to the mooring line.
