A device for moving a rock-drilling machine on a running rail by means of a four-wheeled truck is proposed. This four-wheeled truck is designed in such a way that quick mounting of the drilling device and quick dismantling of the same from the running rail is ensured. To this end, segments which can be swung out of the way are provided for the rollers on each side, which can accordingly be secured in place.
