Wheelchair users need an effective means of bypassing stairs and accessing decks and porches. Ramps and stairlifts may not be suitable for all applications. Vertical platform lifts (VPLs) are the ideal option in homes and commercial buildings where space is a constraint. They allow wheelchair users to access raised decks and porches in multi-level buildings without leaving the comfort of their assistive device. They can be installed both outdoors and indoors. Top models work on hydraulics or electrical energy.
