Trail King has introduced several updates to its lineup of live-bottom trailers, ranging from maintenance access to the hopper walls.

Bolt-on upper coupler/kingpin and front fenders improve access for maintenance teams, while the hopper walls are now made with an AR450 wear plate that’s .160 inches (4 mm) thick in the rear half of the trailer. The same wear plate is also an option for the full length.

Round hopper cross members have been attached to the sidewall using cast steel mountings, helping to keep material from building up, the company says. A heavy-duty, four-inch pitch roller chain and frictionless drive system support horizontal discharge while unloading in one revolution or less.

Aerodynamics are enhanced with smooth aluminum or steel side panels.
