ABSTRACT:
A lift apparatus is disclosed. Particularly, a lift apparatus may comprise a support frame and a platform movably coupled to the support frame. Further, the platform may comprise at least one roller and a transmission connected to the at least one roller of the assembly, wherein rotation of the at least one roller causes the platform to move relative to the support frame. In another aspect of the present invention, a lift apparatus may include a telescoping platform. The present invention also contemplates a method of moving a wheelchair lift. Particularly, a wheelchair may be positioned such that at least one wheel of the wheelchair contacts a drive mechanism of a platform or a telescoping platform that are positioned at an initial position. Further, the at least one wheel of the wheelchair may be rotated to cause the platform or the telescoping platform to move relative to their initial positions.
