Abstract
A traction device for a dual wheel set. The traction device includes side-members and cross-members, the side-members fitted to the inner side of an inside wheel and the outer side of an outside wheel. A cinch line extended around the dual wheel set at the juncture between the wheels and provided with engaging ends configured to draw the ends together in a cinching action to draw the cross-members into the juncture and thereby tighten the traction device on the dual wheel set.
