A platform lift communicates between a garage floor and the floor of the attic space above. At the upper level, means are provided so the platform lift seals with the ceiling and functions as part of the ceiling while in its uppermost position. Electric power to turn the respective lift shafts is used to urge the lift strands which circle under the platform pulley wheels located within the corners of the platform. The respective strands are collected or released from the lift cranes on the floor above. Each crane has a wind spool driven by the respective rotary transmission coupled to an electric motor through reduction gears. All power to the lift is wired in common through an operable reversible constant-off switch.
