Abstract (en)
Method for vibratory driving of an object, in particular a pile or sheet piling for introducing into or removing from the ground. The object is fixed to a vibrating device. In the device a first pair of eccentric rotatable weights (5,6) is driven by a first hydraulic motor (3) and a second pair of eccentric rotatable weights (7,8) is driven by a second hydraulic motor (4). A difference in phase between the alternating forces generated by the first pair (5,6) and the second pair (7,8) is changed by temporarily changing the ratio of the liquid flow to each of the motors (3,4). <IMAGE>
