<p>Lift cage provided with a guard extending downwards for preventing persons to fall down into the lift shaft below the lift cage at emergency evacuation, the guard being articulated to the bottom of the lift cage immediately below the floor at the lift cage door. Furthermore the guard is controlled by a roller at the lower edge of the guard. This roller runs in a U-shaped guide that is applied to a lateral wall of the shaft. The guide runs vertically over the entirely height of the lift shaft but in the lower end were the guide bends inward and transcends into a horizontal section. In this way the guard will be maintained vertical but when it comes close to its most lowered position where the guard is swung in below the bottom of the lift cage. The lift cage guard can in this way simply and efficiently be used also at later installations of lifts were there its no pit below the lift cage in its bottom position. <IMAGE></p> |
