DRILLING MACHINE FOR FOUNDATION PILES COMPRISING AN ELECTRIC ENERGY RECOVERY WINCH
A self-propelling drilling machine (1) comprises: an undercarriage (10), a rotary tower (12), a mast (21); a kelly bar (22) supported by the mast (21), a drilling tool (40) fixed at one end (221) of the kelly bar (22), a winch (23) associated with the kelly bar (22) to move the kelly bar (22) upwards or downwards, and moving means connected to the winch (23) to rotate the winch (23). The moving means comprise an electric rotary machine (50) configured to operate as an electric motor suitable for rotating the winch (23) and as an electric generator during the lowering of the kelly bar (22) that causes a rotation of the winch (23). The machine (1) comprises a power supply unit (60) operatively connected to the electric rotary machine (50).
