Only Collins Dollies are approved for unlimited distances. Other dollies explicitly state they are NOT approved for freeway use, speeds, or distances.

The Safest Dolly – When Professionalism Matters

Collins’ backup Safety Ratchet System (SRS) allows you to safely and comfortably raise heavier vehicles, operate in all types of weather, lift against walls, and has prevented countless accidents while raising and towing vehicles. Although highly recommended, they are secondary to raising the vehicle.

The Most User-Friendly Dolly – When Versatility Matters

All Collins Cross Rail pairs work with all Collins dollies. Tires and wheels are interchangeable, so any size tire works with any dolly model. Collins Dollies are built for easy maintenance and repair; and are backed by the industry’s best warranty and customer service. That means less downtime–and more time on the road.

The Widest Dolly – When Size Matters

Collins’ T12 Cross Rails extend wide, providing 104″ of usable span, accommodating utility trailers, extra-wide vehicles, boat trailers, and dually trucks. Only Collins provides patented double True Positive Camber, designed to keep loads safe and dolly wheels vertical, resulting in extended tire life.

The Lightest Dolly – When Health Matters

The scales don’t lie. Collins offers the lightest-weight dollies in the industry, helping make the job easier, safer, and faster for operators.
