The invention relates to a dragging type boarding lifting system. The system comprises a foldable sliding rail, a lifting platform, a driving device and a control unit, the foldable sliding rail is arranged between a passenger cabin door of an airplane and the ground during boarding, the lifting platform is configured to slide along the foldable sliding rail, and the driving device is used for driving the lifting platform and comprises a winch and a driving motor. The driving device further comprises a laser range finder and a capstan angle encoder, and the control unit receives position data measured by the laser range finder and capstan angle data measured by the capstan angle encoder and calculates the instantaneous speed and the instantaneous acceleration of the lifting platform. Therefore, the speed and/or the acceleration of the lifting platform are/is controlled within a rated value range by controlling the current of the driving motor. According to the technical scheme, the system has the following beneficial technical effects that the impact problem of starting and stopping of the lifting platform is solved, and therefore the comfort of a prone patient in the process of using the system is improved.
