The invention discloses a single-cylinder bolt type crane boom pin release noise reduction system and method. The system comprises a cylinder boom pin telescopic mechanism, an oil supply component, a telescopic oil cylinder, a first pressure adjusting component, a second pressure adjusting component, a back pressure mechanism, a controller and a measuring element. The cylinder and arm pin telescopic mechanism comprises a cylinder pin oil cylinder and an arm pin oil cylinder; the cylinder pin oil cylinder and the arm pin oil cylinder are respectively connected with the telescopic oil cylinder and are used for pulling down and releasing a cylinder pin and an arm pin; the telescopic oil cylinder is connected with the oil supply component and connected with the cylinder arm pin telescopic mechanism through an inner core pipe. The oil supply component comprises a hydraulic pump and a first electromagnetic directional valve; the first pressure adjusting part is arranged in the oil supply part, and the backpressure mechanism is arranged between the first electromagnetic reversing valve and the hydraulic oil tank; the controller controls opening and closing of the cylinder arm pin telescopic mechanism and all the parts according to feedback data of the measuring element and is used for pulling out the arm pin and controlling the arm pin releasing process, and the system and method can reduce arm pin releasing noise and counteract the impact force released by the arm pin.
