<p>Unintended movement governor for limiting the movement of a moving object, which unintended movement governor comprises a pulley (1), a part (2), coupling means (5), with which the part (2) is connected to the pulley (1), for rotating the part (2) via the coupling means along with the pulley (1), and means (3) that can be switched into a state limiting the movement of the part (2). When the means (3) are in the state limiting the movement of the part (2) they are arranged to impair the rotation of the part (2) along with the pulley (1) such that relative movement is caused between the part (2) and the pulley (1) if the pulley (1) rotates, and that when the part (2) is in the limited state in terms of its movement it is arranged to stop the rotation of the pulley (1) or at least essentially decelerate the rotation after the part (2) and the pulley (1) have moved a predetermined amount (A, B) with respect to each other. The elevator according to the invention comprises an unintended movement governor as defined in the preceding.</p> |
