ABSTRACT:
This grab bucket comprises a pair of shells or scoops pivoted to the lower portion of a frame structure and operatively connected to a vertical hydraulic cylinder and piston actuator of which the piston rod is held against translation in relation to said frame structure, the upper end of the cylinder of said actuator carrying the pivot pins of links connected to said pair of shells or scoops. The frame structure comprises on the one hand an upper rocker rigid with the piston rod of said hydraulic actuator and on the other hand a frame structure body detachable from said rocker. The shells themselves are detachable from the base of the hydraulic cylinder to permit the operation of the grab bucket not only as a digging bucket but also as a rehandling bucket after disassembling the frame structure body and connecting the links to the rocker.
