National Wheel-O-Vator Inc. manufactures various commercial and residential models of vertical platform lifts.

With the use of an Acme screw or a Hydraulic drive, a vertical platform lift is a safe, economical, and space effective way to overcome architectural barriers up to twelve feet high. In commercial applications, the lifts satisfy the requirements of ADA laws when properly installed. The Acme screw drive has an automatic lubricating device to minimize service needs and maximize durability. The Hydraulic drive gives a faster ride.

Custom installations are often made in existing structures where "standard" models would be unsuitable.
