A rope that is designed to land on the bottom of a river, etc.; A predetermined back tension is always applied to the rope, and the weight always maintains a predetermined back tension even when the ship moves in the vertical direction. a winding drum that pays out or winds up the rope so that it stably lands on the bottom of the water in a received state; and a vertical movement detection unit that determines the amount of vertical movement of the suspended load based on the amount of payout or winding of the rope. and; a control circuit that outputs a hoisting and lowering control command so that the suspended load always maintains a constant height with respect to the horizontal plane based on the determined vertical movement amount; and; A device that detects the height from the bottom of the water and prevents the suspended load of a crane ship from swinging. (2) Utility Model Registration The device for preventing swinging of a suspended load as set forth in claim 1, characterized in that the back tension is applied by a tension reel attached to a winding drum. A device that prevents a suspended load from swinging. (3) In the device for preventing swinging of a suspended load as set forth in claim 1 or 2 of the utility model registration claim,
Swinging of a suspended load, characterized in that the amount of payout and/or winding of the rope is determined by a signal from a device that detects the rotation of a drum, such as a pulse pickup or a potentiometer attached to the winding drum. A device that prevents

Claims

[Claims for Utility Model Registration] (1) A crane on a crane ship has a crane whose boom is lowered vertically into water with a weight attached from a position close to the tip midway from the tip to the base, and the weight is always kept in the sea (water). A rope that is adapted to land on the bottom; a state in which a predetermined back tension is always applied to the rope, and the weight always receives a predetermined back tension even when the ship moves in the vertical direction. a winding drum that pays out or winds up the rope so that it stably lands on the seabed; a vertical movement detector that calculates the amount of vertical movement of the suspended load based on the amount of payout or winding of the rope; a control circuit that outputs a hoisting and lowering control command so that the suspended load always maintains a constant height with respect to the horizontal plane based on the vertical movement amount determined; A device to prevent swinging of suspended cargo on a crane ship using height detection. (2) Utility Model Registration The device for preventing swinging of a suspended load as set forth in claim 1 is characterized in that the back tension is applied by a tension reel attached to a winding drum. Device to prevent swinging of suspended loads. (3) Utility model registration Claims In the device for preventing swinging of a suspended load according to claim 1 or 2, the amount of the rope to be paid out/taken up is controlled by a pulse pick-up or a potentiometer attached to the take-up drum. A swing prevention device for a suspended load, characterized in that the device is determined by a signal from a device for detecting the rotation of a drum such as the above.
