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 machine and method utilize a tracked undercarriage including a frame with a central body, front and rear transverse assemblies connected to the central body and extending on opposite sides. Each of a pair of lateral tracks is connected, at the front and at the rear, to ends of the transverse assemblies. The base machine includes excavation equipment having different working positions/configurations. Each of a pair of front load cells of the tracked undercarriage is mounted between a lateral track and the front transverse assembly. Each of a pair of rear load cells is mounted between a lateral track and the rear transverse assembly. Each load detects force data indicating the reaction force exerted between the associated lateral track and the respective transverse assembly. A control system computes a barycentre planar position of the machine situated substantially at a reference plane computed as a function of the force data.

Abstract: An excavation tool for making ground excavations for panels and diaphragms includes at least one rotary excavation drum. At least one frame is adapted to support the excavation drum. At least one pump is adapted for suction of an excavation fluid. A brushless electric motor is adapted to put in rotation the at least one excavation drum. At least one mechanical reducer is operationally connected to the electric motor and the at least one excavation drum. The electric motor is installed in the frame and coaxial to the at least one excavation drum. The at least one mechanical reducer is coaxial to the electric motor and the at least one excavation drum. The at least one mechanical reducer is adapted to transfer rotary motion from the electric motor to the at least one excavation drum.
