A hydraulic cylinder equipped with a booster of the present invention is a hydraulic cylinder containing a piston connected to a piston rod on one side. The hydraulic cylinder is provided with an adjustment part that adjusts the pressure in a rear compartment so that a hydraulic oil pressure in the rear compartment does not exceed a maximum hydraulic pressure before a pressure increase when the position of the piston is 95 degrees or higher when the position of the piston is set to 0 when the hydraulic cylinder is maximally contracted, and the position of the piston is set to 100 when the hydraulic cylinder is fully expanded. Therefore, the present invention can prevent the cylinder from being damaged by operation of the booster when the cylinder is fully expanded. 본 발명의 승압기를 구비한 유압실린더는, 일측으로 피스톤 로드가 연결된 피스톤이 수납된 유압실린더에 있어서, 상기 유압실린더가 최대로 수축하였을 때 피스톤의 위치를 0, 최대로 확장하였을 때 피스톤의 위치를 100이라 하였을 때, 피스톤의 위치가 95이상의 위치에서 후실의 작동유 유압이 승압 이전의 최대유압을 넘어서지 않도록 후실의 압력을 조절하는 조절부를 구비한 것을 특징으로 한다.
