<p>The present invention provides a counterweight-linked floating gantry crane and a vessel for returning aggregate using same. The counterweight-linked floating gantry crane and the vessel for returning aggregate using same, according to the present invention, can efficiently install a floating structure in the ocean or transport heavy objects by sea by providing a barge that is integrally formed with a gantry crane, and more specifically, can conveniently and easily collect the aggregate from sea and transfer same to land or transfer the aggregate from an aggregate transport vessel to land, and can conserve winch driving force by driving a wire winch of the gantry crane by means of linking with the counterweight. The counterweight-linked floating gantry crane comprises: the barge which moves on sea; a gantry crane module which is integrally formed on an upper portion of the barge and comprises a wire winch module for inducing operation of a trolley that moves along a girder; and a counterweight driving device, which is integrally formed on the upper portion of the barge and is provided with a counterweight that is linked to and moves with the wire winch module of the gantry crane module, for conserving the driving force of the wire winch module. A vessel for returning aggregate according to the present invention comprises: a barge which moves on sea; a gantry crane module which is integrally formed with an upper portion of the barge and is provided with a wire winch module for inducing driving and moving of a bucket for transporting the aggregate; a counterweight driving device, which is integrally formed with the upper portion of the barge and is provided with a counterweight that is linked to and moves with the wire winch module of the gantry crane module, for conserving the driving force of the wire winch module; and an aggregate returning device for accommodating the aggregate that is transported by the bucket of the gantry crane module and returning the accommodated aggregate to land.</p> |
