Trail King debuts three new automatic kingpin steering trailers

At a truck stop on the edge of an industrial corridor, a lowboy eases through a turn that would make most operators wince. There’s no hesitation, no tire scrub, no frantic mirror checks. The trailer pivots smoothly behind the tractor, its load steady, its path precise. This moment, quiet, controlled, almost effortless, is exactly what Trail King Industries had in mind when it set out to rethink heavy haul transportation.

Trail King TK110HD-S

That vision has now been realized in the TK110HD-S, TK160HDG-S, and TK130HES-S, Trail King’s newly unveiled automatic kingpin steering trailers. More than new models, these trailers represent a fundamental shift in heavy-haul equipment design, informed not only by engineering innovation but also by the real-world experience of the operators who rely on them every day, the company said. While Trail King has long incorporated kingpin steering technology across other platforms, this capability has now been adapted to additional models to better meet the evolving demands of today’s heavy-haul applications.

Trail King didn’t build the TK110HD-S in isolation. Instead, the company collaborated closely with leaders across the heavy haul community, gathering real-world insights about tight job sites, restrictive routes, and the constant pressure to move bigger loads more efficiently. The result is a trailer that blends Trail King’s engineering pedigree with practical, job-tested solutions, delivering what many in the industry are already calling one of the most maneuverable and versatile trailers available today, according to the company.

At its core, the TK110HD-S is built for performance, the company said. The trailer features a 9-foot-wide, 53-foot-long frame and a three-axle configuration, with the option of a removable fourth steering axle for added flexibility. Its automatic kingpin steering system delivers 40 degrees of steering angle, allowing operators to confidently navigate sharp turns, congested job sites and urban environments that were once considered off-limits for heavy haul equipment.

Just as critical is the trailer’s ultra-low 14-inch loaded deck height, a feature that opens doors on low-clearance routes and reduces the need for costly detours or permits. Pair that with Trail King’s robust gooseneck design, offering a minimum of 125 inches of swing clearance, and the TK110HD-S optimizes weight distribution while enhancing stability and safety under load.

But Trail King didn’t stop at maneuverability. Flexibility is woven into every aspect of the TK110HD-S. The trailer is available with an extendable deck, along with multiple deck styles and lengths to suit a wide range of hauling applications. Customizable axle configurations further allow operators to tailor the trailer to their specific needs, whether they’re transporting construction equipment, specialized machinery, or oversized loads that demand absolute precision.

“Durability and long-term value are equally central to design. Built in the United States, the TK110HD-S is built using high-quality components sourced primarily from North American suppliers,” Trail King said. “This commitment not only ensures reliability in demanding conditions but also simplifies service and support, an often-overlooked factor that can make or break productivity in the field.”

The TK160HDG-S closely mirrors Trail King’s traditional 13-axle configuration, consisting of a jeep, trailer and booster, while incorporating kingpin steering on the trailer. The unit features a 108-inch overall width, multiple deck styles and deck heights, and offers modular components with a range of customizable options, allowing operators to configure the setup to meet specific hauling requirements.

Trail King TK130HES-S

The TK130HES-S is an extendable-deck, fixed hydraulic gooseneck trailer equipped with six steerable axles. It also features a 108-inch width and a loaded deck height of 38”. The trailer is designed with an extendable mono-beam deck which provides added flexibility in kingpin-to-axle group spacing, and the trailer can be designed to accommodate both jeep and booster configurations for enhanced versatility.

“For us, it’s always been about building equipment that helps our customers succeed,” said Ty Hanten, vice president of sales and marketing at Trail King. “The TK110HD-S, TK160HDG-S, and the TK130HES-S are a reflection of that commitment, designed not just to meet expectations, but to exceed them.”

With the launch of the new steering designs, Hanten said Trail King underscores its role as an innovator in the heavy haul industry.

By listening closely to operators and pushing the boundaries of trailer design, the company has delivered a solution that doesn’t just move heavy loads, it moves the entire industry forward, according to Hanten

All three steerable trailer models were on show at ConExpo in Las Vegas in early March.
