A hoisting device (1) for a vehicle has a vertical column (2) that forms a frame. The hoisting device also has a carriage (7) that is movable along the column by an adequate driver (12) to rotate a threaded rod (9). The hoisting device also has a nut that is integral with the carriage where the load to be lifted and resting on the lifting arms (8) moves along. The hoisting device also has an extension ferrule having an inner thread for its mounting on the lower end of the threaded rod and openings where a tool is inserted to ensure the screwing and unscrewing of the ferrule.
