Safety device to make the unlocking doors of elevators and hoists reopen when their closure is hindered by any impediment, such as a person or other obstacle, characterized by the fact that between the door link clamp (or part of it) with the chain that directly drags in the movement of opening and closing, is inserted a dynamometric device of adjustable elasticity depending on the drag load, this dynamometric device combined with an electrical contact acting on regulating organs of the chain control motor when the normal effort of this is exceeded.
