  • Running mechanism for chain hoists, load carrying means for trailing cable
    Patent number: 5881650
    Abstract: A running mechanism which travels on a running rail comprising a web and a flange. Running wheels are supported by the flange on opposite sides of the web and are rotatably mounted in frame parts which are connected by an articulation arranged below the running rail such that the frame parts swivel open or closed laterally about a swivel pin. A load acts on at least one of the frame parts at the height of or below the swivel pin and holds the frame parts swiveled closed towards the web on both sides by means of a closing moment generated by the load. Guide rollers, one of which is rotatably supported in the frame part, are supported on opposite sides of the web.
