Zusammenfassung:PURPOSE:To enable the optimum alteration of a grasping position irrespective of the length of the pile, by a method wherein an exciter having a hydraulic cylinder-operated chuck device at a lower end is attached to a bracket set to a point of an arm of a power shovel through the medium of a vibration-insulating rubber. CONSTITUTION:An exciter 20, having an eccentric weight built into a case and being rotated by a hydraulic motor, is attached to a bracket part 10, set in a pin hole in a point of an arm of a power shovel, through the medium of a plurality of vibration-insulating rubbers 19, and a chuck device 30 is placed in juxtaposition under the exciter 20. The chuck device 30 has a front side opening, through which a steel sheet pile 6 can be inserted into a base board 32, and is provided with hydraulic cylinders 34 and 34', having chuck claws 35 and 35' at its point, positioned at both sides of the opening part. This permits the vertical fluctuation of a grasping of a pile, whereby a pile can be driven and pulled off irrespective of the length of the pile.
