Abstract
A travelling mechanism for travelling rail having flange parts and web parts. The mechanism including rest running wheels located opposite to each other which can rest on the flange parts. The flange sides of the rail guide rollers are arranged parallel to web rest in front of and behind each running wheel on both sides. The guide rollers, like the running wheels, are rotatably mounted in lateral bars connected below the travelling rail. The lateral bars are spaced from each other and connected to each other by a connecting traverse. To create a travelling mechanism that is adjustable, whereby the running wheels always run relatively close to the web, the travelling mechanism be adjustable to different flange widths by the use of connecting traverses of different lengths. The spacing between the axes of the guide rollers is variable independently of the running.
