Traction device for a wheeled vehicle

摘要

The present disclosure concerns an emergency traction device that may be easily and securely fitted on vehicles having tires of different diameters and widths. A single winch sizes and secures the traction device for the proper tire diameter and then for the proper tire width. Traction can be further enhanced with members that substantially circumscribe the tire. Operation of the traction device can be enhanced by providing nonreversible gearing for operating the winch.
