GREAT BEND, Kan. — Doonan Specialized Trailer, a manufacturer of platform trailers, including custom flatbeds, drop-decks, oilfield trailers, extendibles, RGN low-beds and double drops, have designed and constructed a new specialty coil hauler trailer.


The new custom 48-foot by 96-inch Black Gold Coil Hauler trailer was developed specifically for hauling steel coils shotgun style (where the eye of the coil is facing forward), recessed inside a well, for the reason that coils can “pack a punch” if they get loose, according to Mike Gordy, co-manager of operations at Doonan.

Designed with two outer perimeter beams with 1-inch by 5-inch top and bottom flanges, the new Doonan manufactured trailer features a well opening in the center that measures 19-feet long by 76-inches wide with recessed concave beams to safely secure the coil load.

“Coils are generally some of the toughest types of freight to haul because of their concentrated weight in one small area on the trailer,” Gordy said. “One of the many advantages of Doonan’s trailer design is that Doonan has engineered the coil well closer to the axles in order to transfer more weight onto the trailer axles.”

Coils can range in size from something relatively small like 5,000 pounds to over 60,000 pounds. The new flatbed coil hauler trailer’s Gross Vehicle Weight Rating (GVWR) is 98,000 pounds. The GVWR is based on a tri-axle trailer with disc brakes.

The trailer is also designed to have a tarp system installed, so the coils are protected from the elements and arrive at their destination safe and sound. Nine custom pockets were installed along the sides of the trailer for this application.

“We couldn’t be more pleased with the design and weight this trailer can hold,” Gordy said. “This new specialty trailer demonstrates our commitment and focus on taking our products to the next level, and providing customers with innovative solutions that lead the industry.”
