By adjusting the counterweight of the load 5 and the height to which the load 5 is lowered, the device can be applied to different vehicle models for heavy load tests on vehicle interiors. The load clamping fixture 4 is slidably sleeved on the lower end of the outer wall of the height scale 2, and the outer wall of the load clamping fixture 4 is fixedly connected to the movable portion of the lifting drive mechanism 3.
