A lifting device for vehicles includes a column forming a frame, extending substantially vertically above a base, and a lifter movable along the column by controlling the rotation of a threaded rod by a driving device and by the movement, along the threaded rod, of a nut secured to a carriage on which the load to be lifted can rest. There is a fall-arresting safety device including a ratchet occupying at least a first unlocked position and a locked position engaging with at least one tooth of a ratchet wheel so as to lock the rotation of the threaded rod. There is a retaining device for the ratchet in the unlocked position and a controller for the return of the ratchet to the locked position.
