CONSTITUTION: A lift device of a floating pier for a port is comprised as follows. A horizontal frame(21) with a fixing pin(22) assembled in a second support is moved in a cantilever structure by pushing and pulling a strut fixed to the bottom of the horizontal frame using a pusher device. The pusher device comprises first supports, a backing, a piston rod(5), a pressure cylinder, and a hydraulic jack(4). The first supports are fixed to the top surface of a support frame. The backing is assembled in a hinge bar which horizontally penetrates through the first supports. The piston rod is fixed to the backing and has a fastening ring. The pressure cylinder is assembled with a pressure lever. The hydraulic jack has a pressure release valve. [Reference numerals] (AA) Drawing 6
