The OTS of claim 1, wherein the trolley assembly is configured to be manually moveable along the rail. 3. The OTS of claim 1, wherein the trolley assembly includes a motion control system operable to control the motion of the trolley assembly along the rail,and an actuating lever connected to the motion control system and operable to provide a controlled motion along the rail. 4. The OTS of claim 3, wherein the actuating lever is an articulating actuating lever. 5. The OTS of claim 3, wherein the motion control system includes a braking system to prevent the motion of the trolley assembly along the rail in an uncontrollable manner. 6. The OTS of claim 5, wherein the braking system includes a friction unidirectional brake clutch, andwherein the friction unidirectional brake clutch is operable to control a speed of the trolley assembly in a downward direction along the rail. 7. The OTS of claim 3, wherein the actuating lever is coupled to a locking system that includes a spring loaded module that is configured to prevent the motion of the trolley assembly along the rail. 8. The OTS of claim 7, wherein the actuating lever is an articulating actuating lever, wherein the articulating actuating lever is configured to pivot perpendicularly from the rail from a locking position adjacent to the rail to an operational position pivotally away from the rail,wherein the locking system is configured to prevent movement of the trolley assembly along the rail when the articulating actuating lever is in the locking position, andwherein the spring loaded module is configured to keep the articulating actuating lever in the locking position. 9. The OTS of claim 1, wherein the object carrier is a foldable and collapsible object carrier. 10. The OTS of claim 1, wherein the flight of steps is a ladder, the plurality of steps is a plurality of rungs, and the base is a pair of ladder legs. 11. The OTS of claim 1, further including a retractable reel having a flexible material wound around the retractable reel, wherein the rail has a bottom end and a top end,wherein the retractable reel is attached to the rail at the top end, andwherein the flexible material has a first end attached to the retractable reel and a second end attached to the trolley assembly. 12. The OTS of claim 11, wherein the flexible material is a steel cable. 13. A method for transporting an object on a flight of steps with an object transfer system (“OTS”), the method comprising: receiving the object on an object carrier,wherein the object carrier is attached to a trolley assembly, andwherein the trolley assembly is movably attached to a rail positioned as a handrail on the flight of steps, wherein the flight of steps comprises a base and a plurality of steps;releasing a locking system within the trolley assembly when an actuating lever is pivoted;moving the trolley assembly along the rail; andlocking the trolley assembly after moving the trolley assembly. 14. The method of claim 13, further including unfolding the object carrier prior to receiving the object on the object carrier. 15. The method of claim 13, wherein pivoting the actuating lever includes pivoting the actuating lever from a locking position adjacent to the rail to an operational position away from the rail, andwherein pivoting the actuating lever to the operational position includes releasing a spring loaded module within the trolley assembly. 16. The method of claim 15, wherein locking the trolley assembly includes pivoting the actuating lever from the operational position to the locking position, and activating the spring loaded module in response to pivoting the actuating lever to the locking position. 17. The method of claim 16, further includes applying a friction unidirectional brake clutch against the rail in response to the trolley assembly moving in a downward direction along the rail. 18. The method of claim 17, wherein moving the trolley assembly along the rail includes moving the trolley assembly along the rail in an upward direction, and retracting a flexible material attached to the trolley assembly with a retractable reel when moving the trolley assembly along the rail in the upward direction. 19. The method of claim 17, wherein moving the trolley assembly along the rail includes moving the trolley assembly along the rail in a downward direction, and extending a flexible material attached to the trolley assembly with a retractable reel when moving the trolley assembly along the rail in the downward direction. 20.
