Side grip vibratory pile driver

A side grip pile driver attachment 1 suitable for a working machine comprising a pair of jaw members 2a, 2b movably attached, each jaw member having a clamping interface and a driving means arranged to move jaw members for clamping objects between the interfaces. Each jaw member comprises a jaw arm 3 and a gripping head 5, where the jaw arm is attached to the gripping head via an elastomer member 14. At least one gripping head comprises a vibrator device 22 for vibrating the gripping head such that the gripping head is couplable to an object and can allow mutual vibration between the gripping head and the object in a direction parallel to the longitudinal axis of the object when clamped. The elastomer member allows relative movement between the gripping head and the jaw arm in a direction parallel to the longitudinal axis of the object while transferring clamping force from the jaw arm to the gripping head.
