ABSTRACT:
The grab bucket of the present invention comprises the grabbing claws provided for opening and closing around the main body suspended from a crane, the electromagnet provided movably upward and downward from the ordinary location just underneath the main body to the dredging position on the bed and the side claws provided movably upward and downward to prevent the scrap from overflowing so as to increase the amount of the scrap to be loaded and unloaded. The side claws prevent the side plates and bed surface from being damaged. In the case of dredging the scrap on the bed, only the electromagnet proceeds unloading, thus the bed is not damaged by the grabbing claws.
