发明名称 METHOD AND APPARATUS FOR REACHING FROM OUTSIDE AN UPPER LEVEL OF A TALL STRUCTURE
摘要 An embodiment of the invention is directed to a system having a pulley attached to a building. A closed loop of cable is installed around the pulley. The loop is of sufficient length so as to reach, when deployed outside of the building, below the pulley to where emergency personnel gather in an area next to a base of the building (when responding to a disaster situation in the building). A winch around which the loop is to be operatively installed is located in the area next to the base. Other embodiments are also described and claimed.
