The present invention relates to a vibration reducing device for a pump tower, capable of obtaining structural stability when a sliding unit is installed to correspond to a vertical direction. The vibration reducing device for a pump tower includes: a pipe assembly loading and unloading liquefied natural gas into a cargo tank; a base plate connected to be horizontal to a lower end of the pipe assembly, wherein a connection hole is formed in the base plate to be vertically penetrated; a guide unit in which a base cone of a lower end is connected to a bottom surface of the cargo tank, and a guide part of an upper end with a guide surface in the forward and backward directions and the horizontal direction is installed to be vertically penetrated in the connection hole; multiple lower sliding units connected to a lower surface of the base plate to be positioned in the forward and backward directions and the horizontal direction of the guide part, wherein one side of the lower sliding units is attached to vertically slide in the forward and backward directions and the horizontal direction of the guide part; and multiple upper sliding units connected to an upper surface of the base plate to be positioned in the forward and backward directions and the horizontal direction of the guide part, wherein one side of the upper sliding units is attached to vertically slide in the forward and backward directions and the horizontal direction of the guide part. 본 발명은 펌프 타워의 진동 저감장치에 관한 것으로, 카고탱크의 내부로 액화천연가스를 로딩 및 언로딩시키는 파이프 조립체와, 상기 파이프 조립체의 하단에 수평하게 결합되며, 결합홀이 상하로 관통 형성되는 베이스 플레이트와, 하단의 베이스 콘이 상기 카고탱크의 바닥면에 결합되며, 전후좌우 방향에 가이드면이 형성된 상단의 가이드부가 상기 결합홀에 상하로 관통 위치되는 가이드유닛과, 상기 가이드부의 전후좌우 방향에 위치되도록 상기 베이스 플레이트의 하면에 결합되며, 일측면이 상기 가이드부의 전후좌우 방향에 상하로 슬라이딩 가능하게 밀착되는 다수의 하부 슬라이딩유닛 및, 상기 가이드부의 전후좌우 방향에 위치되도록 상기 베이스 플레이트의 상면에 결합되며, 일측면이 상기 가이드부의 전후좌우 방향에 상하로 슬라이딩 가능하게 밀착되는 다수의 상부 슬라이딩유닛을 포함한다.
