Title:
SWING-MOTION REDUCING DEVICE
Document Type and Number:
Japanese Patent JP2017030589
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce the swinging of a hull and to suppress a heel.SOLUTION: A hull 2 is provided with a swing-motion reducing device body 3 which is equipped with a guide rail 6 disposed in a lateral direction, a moving mass 8 movably attached to the guide rail 6 through a guide block 7, and a linear motor 9 for moving the moving mass 8 in the lateral direction. Furthermore, a swing-motion reducing device 1 is formed by being equipped with an oscillation sensor 4 of the hull 2, and a control device 5 of the linear motor 9. On a crane 13 on a ship, when a load 12 held by a spreader 17 is moved to a left side with a trolley 16, moment generated on the hull 2 by the mass and position of the trolley 16 and an article suspended from that is cancelled by control of the control device 5 which moves the moving mass 8 to a right direction. When the oscillation of the hull 2 is detected by the oscillation sensor 4, the moving mass 8 is reciprocated by the control device 5 while shifting a phase in regard to the oscillation of the hull 2.SELECTED DRAWING: Figure 1
