An excavator is provided that includes a grab bucket provided with two shovels; a lifting device for lowering and lifting the grab bucket; and a hydraulic drive device provided with at least one actuator cylinder, which is designed to move the shovels between an open position and a closed position, and is operated by a fluid under pressure supplied along a flexible pipe. The flexible pipe includes at least six reinforcement layers interposed between an inner tube and an outer tube, and is provided with a plurality of intermediate layers, each of which is interposed between two adjacent reinforcement layers so as to ensure adhesion between the reinforcement layers.
