Abstract
Abstract A plurality of posts have a threaded opening on one end adapted to threadedly engage vehicle wheel lugs or studs which normally receive the lug nuts. These posts have integral studs on their other ends for projection through an annular plate member and for receiving attaching nuts which secure the plate member on the posts. The projecting portions of the posts are threaded and of a size to receive the lug nuts so that the latter can be used to hold the plate member on the posts, thus forming a winch drum which can be used by the vehicle to pull itself out of trouble.
