Abstract:
1. An elevator arrangement, comprising: an elevator car arranged to move in an elevator shaft; an element which is disposed in the elevator shaft and is rotatably shiftable between an activated state and an inactivated state; a limiter located in the elevator shaft adjacent the shiftable element; and an activating device configured to shift the element between the activated and inactivated states, wherein said activating device comprises a flexible element selected from a group consisting of a rope, a belt, an elongated wire, a band, and a chain movably attached to a fixed structure of the elevator shaft, the flexible element being physically and continuously connected to the shiftable element in a manner permitting the shiftable element to be shifted by means of the flexible element, wherein, when the shiftable element is in the activated state, the shiftable element is positioned to contact the elevator car to prevent upward travel of the elevator car, wherein, when the shiftable element is in the inactivated state, the shiftable element is positioned to not contact the elevator car so as not to impede upward travel of the elevator car, and wherein the limiter is positioned so as to prevent over rotation of the shiftable element.
