Abstract

PURPOSE: To enable accurate sensing of drag arm state by monitoring the drag arm position and shape on a display unit from the feeding amount of suspended cables for hoisting the respective portions of the arms out of a vessel.
CONSTITUTION: A drag arm 2 suspended from a vessel 1 is supported via its turnnion T, intermediate joint M and head H via respective cables 6, 7, 8 to winches 3 to 5. Potentiometers 10 to 12 for detecting the fed amounts of the cables are provided at the respective winches. The signals from the potentiometers are processed by a calculator on the vessel, and are displayed on a monitor display unit together with drag arm present status 21, maximum depth 20 and with upper deck level 17, the portion T position 16, drag arm storage height to thereby monitor the drag arm for exact prevention of trouble to thereby enhance the dredging effect.
