An emergency rescue system includes a cantilever arm, a gondola, a ground unit, and a cable block. The cantilever arm is operable to be positioned on a roof of a building and extend one or more cables from the roof to the ground. The gondola is operable to be coupled to the cantilever arm with the cables and to travel along the more cables. The ground unit is operable to be positioned on the ground beneath the cantilever arm and to be coupled to the gondola with the cables. The ground unit comprises a motor operable to raise and lower the gondola along the cables and a control system operable to provide controls for the ground unit and the gondola. The cable block is coupled to the cables between the gondola and the cantilever arm and controls the cables as the ground unit raises and lowers the gondola.
