置。 A grab bucket dredger is hoisted by a grab bucket lifting wire from a crane on the ship's hull, is lowered into the water to dredge the soil, is lifted up and carried to a designated dropping position, and is dropped by weighing and recording the amount of soil lifted by the grab bucket dredger. The earth measurement recording device includes a load cell that measures the weight of the grab bucket, a drop position detection switch that issues a drop command when the grab bucket reaches the drop position, and a drop position detection switch that uses a weight symbol from the load cell as an input signal to determine the drop position. After the detection switch has issued a dropping command, the weight of the soil lifted per time is calculated from the difference between the weight signals before and after dropping the grab bucket,
Measuring the amount of soil lifted by a grab bucket dredger, characterized in that it has a calculator that performs this calculation every time the grab bucket is dropped and adds up the total amount of soil lifted, and a recorder that records the output of the calculator. Recording device.
