Abstract
Aerial monocable chairlift or gondola lift having detachable grips for coupling the chairs or gondolas to the continuously moving cable. Each grip, in the form of a plier, has a pair of jaws, the outer profile of the jaws being so designed that the grip passes on support sheaves, hold down sheaves and horizontal wheels in the station. The clamping coil spring is inserted between the ends of the plier levers and extends substantially parallel to the hanger bar articulated on the grip body. A grip operating roller opens the jaws at a platform in the station and the speed of the chair is reduced for loading and/or unloading of the passengers before the grip is again coupled to the cable.
