A knockdown, portable lift is relatively compact and lightweight for transport and use where there is no existing means for lifting a load between a lower surface and an upper surface or where the existing means cannot be used. Components of the lift are stored in a base portion of the lift and are assembled on site for forming a lift frame extending between the upper and lower surfaces. A platform and drive assembly are supported on the lift frame and are driven together up and down tracks on each side of the lift frame using a rotary drive, such as a hand crank or electric motor, to power the drive assembly. The drive assembly is operable by a person on or off the platform from either the upper or lower surface or traversing stairs over which the platform is moving. The drive assembly incorporates a unique overspeed braking system and a unique clutch arrangement.

A lift apparatus for telescopic passenger stairs enabling disabled passengers with impaired mobility to board a plane and to telescopic aeroplane passenger stairs with the said lift. The lift apparatus moves the lift regardless of the degree of extension of the telescopic staircase, with a moveable guide rail installed into a lower staircase, which can travel to the top of an upper staircase if needed. The guide rail in the lower part serves as a fixed guide rail for the lifting platform, onto which a passenger in a wheelchair is wheeled, wherein the platform moves along the guide rail. When the platform reaches the end of the guide rail, it is locked in place, after which the guide rail itself then moves along the track of the upper part of the staircase, wherein it is connected to the guide rail via wheels. The described movement is enabled by a system comprising an endless chain, guide rollers and wheels, a drive sprocket and a drive, and the said guide rail.

An apartment staircase automatic lift, comprising a combined structure of a carrying guiding-rail, a transmission-set main-body and a driving module; wherein the transmission-set main-body is set with a carrying wheel-seat and a transmission-set carrying-shelf; wherein the transmission-set carrying-shelf is set with a foot-pedal; when a person stands on the foot-pedal, the driving module can be controlled to drive the transmission-set main-body and the foot-pedal to move back and forth along the carrying guiding-rail between the upper and lower ends of the carrying guiding-rail; thereby helping the person to go up and down the staircase. The overall structure has the advantages of low cost, easy installation and operation, and compact structure; which can improve the defects of the conventional staircase-lift seat including the large volume size, occupying large staircase space, and being inconvenient to be arranged in a general apartment staircase.

A personal stair lift device transports a handicapped or immobile individual of higher than average weight capacity up and down a stairway on a chair assembly supported on a dual rail mount assembly. The stair lift device is used on a stairway on a dual track system aligned on both sides of the stairwell, connected to dual metal pipes, and is further connected to a plurality of metal brackets, containing steel braided cables. Braided cables are connected to guide wheels that can lift heavier weight capacity individuals.

A wheelchair lift apparatus that includes a stand that includes a pair of inclined rails; and a platform adapted to carry a wheelchair, wherein the platform includes a driving portion and a driven portion for moving the platform along the rails, wherein, when the driving portion actuates the driven portion in a first direction, the platform ascends along the rails, wherein, when the driving portion actuates the driven portion in a second and opposite direction, the platform descends along the rails.

An electric stair lift system for transporting people and/or cargo up and down a flight of stairs includes a pair of parallel rails, a platform that is slidably engaged with the rails, an electric winch with a take-up spool, and pair of straps attached between the slidable platform and the take-up spool of the winch. In a preferred embodiment, the electric stair lift system is portable, so that it may be installed in such a way that it may be easily removed, stored and transported, as desired.
