A Transport System for a folding attic stairway that operates between a lower floor and an attic floor and that is comprised of:
- (a) a base assembly made of durable materials with a platform, an end, runners, and a guiding system;
- (b) a cable system between the platform and a winch;
- wherein the cable system is further comprised of a pulley system with a plurality of pulleys configured such that a cable encircles around the pulleys and guides the cable to the location of the winch;
- wherein at least one of the plurality of pulleys resting on the attic floor;
- and
- (c) the winch
- wherein the base assembly of the transport system is suspended by the cable of the cable system and the cable is lengthened and shortened by an operation of the winch and wherein the platform of the base assembly moves up and down an extended configuration of the folding attic stairway which permits the platform while carrying a load and during the operation of the winch, to reach and to rest on the attic floor and then to return back downward on the extended configuration of the folding attic stairway to reach the lower floor.

- wherein the cable system is further comprised of a pulley system with a plurality of pulleys configured such that the cable encircles around the pulleys and guides the cable to the location of the winch;
- wherein at least one of the plurality of pulleys resting on the attic floor;
- and
- (d) the winch
- wherein the base assembly of the transport system is suspended by a cable of the cable system and the cable is lengthened and shortened by an operation of the winch and wherein the platform of the base assembly moves up and down an extended configuration of the folding attic stairway which permits the platform while carrying a load and during the operation of the winch, to reach and to rest on the attic floor and then to return back downward on the extended configuration of the folding attic stairway to reach the lower floor.
