[0002] The hydraulic lifting device, also known as the hydraulic lifting platform, is a multifunctional lifting and loading and unloading mechanical equipment. This device works based on the principle of ordinary hydraulic transmission, involving the pressure transmission of the liquid and the movement of the piston. The hydraulic lifting system is mainly composed of a hydraulic pump, a hydraulic cylinder and a hydraulic valve. In the system, the hydraulic pump generates pressure in the liquid through mechanical force, and then transmits the pressure to the hydraulic cylinder. The piston in the hydraulic cylinder is subjected to the force of the hydraulic oil, thereby performing an upward or downward movement.
