Drilling machine for foundation piles comprising an electric energy recovery winch
A self-propelling drilling machine includes: an undercarriage. a rotary tower, a mast, a kelly bar supported by the mast, a drilling tool fixed at one end of the kelly bar, and a winch associated with the kelly bar to move the kelly bar upwards or downwards. An electric rotary machine is configured to operate as an electric motor suitable for rotating the winch and as an electric generator during the lowering of the kelly bar that causes a rotation of the winch. The machine includes a power supply unit operatively connected to the electric rotary machine.
