Abstract
An elevator includes an elevator hoistway with an elevator car arranged to move therein. The elevator car includes an interior bounded by at least the elevator care roof. A frame structure includes two parallel, horizontal, elongated roof beams that are at a horizontal distance from each other. Between the roof beams is a trough that has an upward-facing base surface, and a standing platform in connection with the roof of the elevator car that includes a standing surface, immediately above which is a space free of the parts of the elevator car and free of the ropes of the elevator, for enabling standing on top of the standing surface at least when the elevator car is situated at a distance from the top end of the elevator hoistway. The standing surface forms at least a part of the base surface of the trough.
