An arrangement for mounting lighting fixtures is provided. The lighting fixture or a plurality of lighting fixtures in a row are mounted on carriages movably disposed on a horizontal rail. The lighting fixtures can be moved from an operating position to a maintenance position by means of a first rope connected to the utmost carriages, whereby the movement of the utmost carriage to the maintenance position will push the carriages in front of it with regard to the direction of movement to a position in which all carriages are positioned close to each other. The lighting fixtures can be moved from a maintenance position to an operating position by means of a second rope being connected to each of the carriages, whereby movement of the utmost carriage to the operating position by means of the first rope will pull the carriages behind it with regard to the direction of movement to a position in which all carriages are positioned a distance apart from each other.
