Abstract:
A guided lift cage which is pivotally mounted to a pair of fixed side rails by a suspension trolley so that the cage is always suspended on a vertical axis, regardless of the axis of the side rails. The path of the side rails may curve from a vertical axis within a shaftway to a horizontal axis above and outside of the shaftway to permit the storage and unloading of the cage, above the shaftway, at a position horizontally offset from the shaftway, to thus provide uninterrupted vertical access to the shaftway in the stored position of the cage.
