A DEPOSIT DREDGING MACHINE USING CRANE

摘要

PURPOSE: A deposit dredging device using a crane is provided to minimize flying suspended materials by dredging a deposit over wide area when being anchored. CONSTITUTION: A deposit dredging device using a crane comprises a horizontal shaft and a vertical shaft of a crane, a suction hopper(22), a rotor(17), a suction pump(16), a deposit suction hose(14), and a sonar(25). The horizontal shaft and the vertical shaft of the crane vary the location of a suction hopper installed in the crane. The suction hopper is fixed to the bottom of the vertical shaft of the crane. One or more deposit suction ports(21) are installed in the suction hopper to suck the deposit. The rotor is installed inside the suction hopper. The suction pump is installed on the upper end of the suction hopper. The suction pump sucks the deposits through the deposit suction port. The deposit suction hose is installed using the horizontal shaft and vertical shaft of the crane.
