ABSTRACT:
A descent device includes a load carrier, a winder unit with a coil of cable for suspending the load carrier in mid-air so as to raise or lower the load carrier, and a retarding unit for impeding downward movement of the load carrier so that the load carrier can move downward at a lower speed to ensure safety of the occupants.
