Abstract

A maintenance trestle is stowable in folded-together form in the floor of an elevator car and has a platform forming the floor. The platform is steplessly adjustable in height between a stored position and an erected position by lifting equipment operating on the scissors principle. Buttons on a car panel that normally control car operations, such as opening and closing doors, can be converted to controlling the extension and retraction of the platform.
