| 摘要 |
A device consisting of two stays (32) hinged together at one end on a housing (11) and supporting wall chains (8) which hold tread chains in place on the tread (26) of the tyre (18) when they are pulled tight as the stays are drawn together by a resilient linkage (23). Arms (12 and 13) or resilient linkages (19) control displacement and vibration of the stays when the wheel (27) is moving. The device enables gripping equipment to be fitted quickly and easily and is suitable for use on snow-covered, muddy, sandy or vegetation-covered terrain.
