Abstract

This invention relates to a grab bucket constituted by a double action jack comprising a piston rod in two parts, mounted coaxial and so as to rotate with respect to one another. This bucket comprises in addition a device for adjusting the angular orientation of the parts of the piston rod, this adjusting device being coupled directly to the said two parts of the rod.
