The invention discloses a large-stroke gravity unloading device with an adjustable load. The large-stroke gravity unloading device comprises a constant tension mechanism and a supporting frame. The supporting frame is fixed on a low-gravity simulation test platform rapid follow-up system; and the constant tension mechanism is installed on the supporting frame and used for achieving load-adjustable large-stroke gravity unloading. According to the invention, rapid mechanical docking with an existing test rack system can be realized, and low-gravity and microgravity environments can be realized in a landing process of a lander; and the device is simple in structure, large in effective stroke, adjustable in load and suitable for simulating a working condition test that the detector lands on the surface of an extraterrestrial celestial body after an engine is shut down in a low-gravity environment.
