摘要： A platform lift apparatus enables the safe movement of objects to and from an attic storage space. The platform lift apparatus includes a frame, a drive mechanism, and a platform. The frame includes internal and external mounting surfaces. The drive mechanism is substantially disposed within the frame and is coupled to the internal mounting surfaces. The drive mechanism includes a plurality of rotatable, parallel shafts with each shaft further including at least one lift drum having an associated lift tether at least partially wound thereon and having an end hanging therefrom. The platform is coupled to each lift tether end and is thereby suspended from the frame. The platform is selectively movable by operation of the drive mechanism within in a vertical dimension between raised and lowered positions. The drive mechanism further comprises an electric motor operatively coupled to the plurality of parallel shafts.

摘要： A platform lift system includes a mounting frame that is fixedly engaged into a scuttle hole formed in a horizontal supporting surface (i.e., attic floor or room ceiling) and a foldable ladder that is supported by the frame. A separate trolley carries a lift platform that may be selectively raised or lowered in order to transport objects to/from the attic space. The trolley is moveable horizontally along a track that may be provided on a floor of the attic space. At a first end of travel of the trolley along the track, the trolley is disposed laterally alongside and vertically offset from the mounting frame such that the space above the mounting frame is unimpeded to permit a user to access the attic space using the deployed ladder. At a second end of travel of the trolley along the track, the trolley is aligned vertically with the mounting frame to permit use of the lift platform.
摘要翻译：平台升降机系统包括固定地接合到形成在水平支撑表面（即阁楼楼层或房间天花板）上的刮水孔中的安装框架和由框架支撑的可折叠梯子。单独的手推车带有可以选择性地升高或降低的升降平台，以将物体运送到阁楼空间。手推车可以沿着可以设在阁楼空间的地板上的轨道水平移动。在手推车沿着轨道行进的第一端，手推车沿着安装框架横向设置并垂直偏移，使得安装框架上方的空间不受阻碍，以允许使用者使用展开的梯子进入阁楼空间。在手推车沿着轨道行进的第二端，手推车与安装框架垂直对准，以允许使用升降平台。
