CONSTITUTION: A vibrating pile-driver device(1) comprises a top frame(10), a mainframe(20), a vibration generating unit(30), a joint portion(40), and a grip unit(50). The top frame is fixed to the working arm(100) of the construction equipment. The mainframe is fixed to the top frame. The vibration generator is arranged in mainframe, and generates the vibration. The joint portion is fixed to the lower part of the vibration generator. The gripper is fixed to the lower part of the joint portion. The gripper holds the one end of the pile. The joint portion comprises first and second members(42,44) and a cylinder portion(46). The second member is rotatably coupled with the first member. The cylinder portion rotates the second member about the first member.
