Abstract
PURPOSE: To strengthen the excavating power of a grab bucket, by a method wherein a water jet mechanism, in which pressurized water is jetted through the end of a cutter of a grab bucket, is installed as an auxiliary excavating means.
CONSTITUTION: A grab bucket 1 is caused to drop in a state to open by mean of hydraulic cylinders 6, 6, and after a cutter end 7 is caused to cut into a given excavating place, the hydraulic cylinders 6, 6 close the grab bucket 1 to perform a given operation. With pressurized water jetted through a jet nozzle 12 at an excavating time, earth and sand positioned in the direction of the cutter end of the bucket 1 is excavated by a water jet action. As a result, a cutting-into force of the cutter end of the grab bucket 1 is promoted to strengthen the excavation power of the grab bucket 1.
