A device, for helping a wheeled vehicle to negotiate an obstacle, includes a stationary framework, a substantially horizontal frame movable between a high position and a low position in which the frame rests on the framework, and an assembly for vertically translating the frame, the assembly is supported by the framework and supports the frame, the drive assembly includes a pair of shears with X-shaped articulated arms, each arm having an end hinged to the frame and an end hinged to the framework, by translation at one end, a drive actuator for driving the frame between the low and high positions. A plate is supported by the frame and, when the frame is in the high position, translatably movable horizontally relative to the frame, so as to come into contact with a vertex of the obstacle, the plate being flush with the neighboring ground when in the low position.
