The lifting system for vines planted in rows and held by at least two tying wires supported by stakes comprises a screw (36) with a bottom end upstream of the displacement direction of a vehicle which carries it. The screw is rotated by a motor (52) and describes a conical envelope, the cone point being the bottom end. The screw is mounted on a U-shaped cradle connected to a plate (32) on a chassis (30) adapted to a tractor.
