Abstract: A device is provided for the movement and mutual assembly of segments of an excavation battery. The device includes four parts: an upper joint, a lower joint, a flexible element and a stop element. The upper joint is connectable to a driving tube. The lower joint is connectable to one segment of the excavation battery. The flexible element connects the upper joint to the lower joint so that the lower joint slides along the flexible element. The stop element limits the sliding of the lower joint away from the upper joint, and includes a ballast with a diameter that is less than a diameter of an inner duct in one segment of the excavation battery.

Abstract: A device for the movement and mutual assembly of segments of an excavation battery, like for example auger or rod segments, for the composition of an excavation battery and for connecting the battery to a digging machine is disclosed. The device has: an upper joint integrally and removably connectable to a driving tube or to a rotary head of the digging machine; a lower joint integrally and removably connectable to a segment of the excavation battery; a flexible element that connects the two joints being constrained with one own end to the upper joint and connected with the other own end to the lower joint, so that the lower joint can slide along the flexible element moving with respect to the upper joint between a disengaged extended position, and an engaged contracted position; and a stop element that limits the sliding of the lower joint away from the upper joint along the flexible element.
