Abstract
An apparatus for adjusting the rollers of a stairlift carriage, for ensuring that the carriage is firmly located on a stairlift rail, includes rollers for engaging one side of the stairlift rail, as well as rollers located on an opposite side of the rail, such that the stairlift rail is located between opposed sets of rollers. To achieve adjustment, the rollers on one side of the rail are located on a common member, which can be displaced toward and away from the stairlift rail.
