The invention discloses a lift car accidental movement protection device and a test method thereof. The lift car accidental movement protection device comprises a test platform, a load motor system, a torque and rotating speed measuring system, a test traction machine, a connecting sleeve, a movable sleeve, a fixing nut and a fixing bolt; a first rotating shaft and a second rotating shaft are arranged at the two ends of the torque and rotating speed measuring system respectively; the first rotating shaft and the second rotating shaft are both rotationally connected with the torque and rotating speed measuring system; a limiting groove is formed in the surface of the first rotating shaft; and a movable plate is fixedly connected to the outer end of the second rotating shaft. A traction machine brake type lift car ascending overspeed protection device and the lift car accidental movement protection device are tested through a method that output torque of a load motor is used to simulate the inertia of a lift system and the mass difference between the two sides of a lift car and a counterweight, and a mathematical model and a formula of the output torque of the load motor simulating the inertia of the lift system and the mass difference between the two sides of the car and the counterweight are provided.
