Multiple stretchers may be located at either or both levels, in which case the retractable cable source provides sufficient tension to assist in pulling the stretcher up the stairway. In the preferred embodiment the retractable cable source includes a housing into which the cable retracts and a loaded spring disposed within the housing.
