<p>The universal curved towbar comprises a pair of curved arm assemblies which are pivoted upon a coupler assembly, and diverge to include bumper mounting assemblies on their distal ends. The curved arm assemblies lie in a lateral plane, with their convex surfaces facing each other, thereby allowing significantly improved clearance between the bumper of the towing vehicle a the arm assemblies themselves. At the distal ends of the curved arm assemblies are three distinct bumper engagement means, including a lower bumper clamping chain which is tensioned against an upper bumper clamp, together with a redundant tensioning through a safety chain attached to the frame of the towed vehicle. At the distal ends of the curved arm assemblies there is further provided a spreader bar assembly, which both adjustably maintains the bumper mounting assemblies in position, and adds significantly increased overall rigidity to the entire towbar assembly.</p> |
