The invention aims to disclose a lifting machine based on a pressure sensor and a descending speed control method of a lifting assembly, and relates to the technical field of vehicle lifting, the lifting machine comprises a hydraulic pump, the lifting assembly, an electromagnetic valve and a proportional-integral regulating valve, and the electromagnetic valve and the proportional-integral regulating valve are connected in series; the lifting assembly is provided with a descending handle, a proximity switch and a pressure sensor, and the descending handle triggers the proximity switch and the pressure sensor at the same time when being pulled down; the proximity switch controls the electromagnetic valve to be opened or closed; the technical effects are that the descending handle synchronously contacts with the proximity switch and the pressure sensor, the proximity switch controls the electromagnetic valve to be opened, and the pressure sensor controls the opening degree of the proportional-integral regulating valve according to the pressure of the descending handle. The descending speed of the hand raising assembly is controlled through the pressure of the descending handle, and use is flexible and convenient.
