Abstract
An adjustable wheelchair lift for a vehicle wherein the lift includes a platform, a mounting structure having two spaced apart, vertically extending, support posts mountable to the vehicle, a linkage for moving the platform to and from the vehicle and a chain-and-sprocket drive for moving the linkage. Each support post has a main portion and an adjustable portion, preferably both being channel shaped. The adjustable portion slides along the main portion until the desired height is reached. The channels also interlock at their edges to prevent lateral movement of the adjustable portion when it is unconnected to the main portion.
