摘要： The present disclosure relates to a vibro-hammer 1 connected to heavy construction equipment, and more particularly, a vibro-hammer 1 having a side grip in which vibrations are prevented from being transmitted to a connected heavy equipment machine to avoid a problem such as a change in a perforation position, the vibro-hammer 1 is firmly connected to a perforated pile to transmit vibrations generated in a gear box to the perforated pile through the side grip and improve workability, arms are gear-coupled to each other to prevent the arms and the side grip from being released from each other due to frequent vibrations, a pair of arms and the side grip can come into close contact with the perforated pile or separated from the performed pile by a single cylinder, the side grip can be easily replaced according a shape of the perforated pile, and applicability and workability is improved.
