Our Best Towing Trailer

The 9 Ton tri-Axle and 10 Ton SuperHoe are no ordinary tri-axle trailers. This is our best towing trailer we build. Axle placement, shorter slipper suspension, wide frame and tire stance, and correct support bracing, provide for more stable balanced loads. This trailer is great towed behind medium duty trucks because of its great balance and stable ride. Add a 2 5/16' Adjustable Gooseneck and there is not a better equipment trailer to tow behind a dually pickup.

Less Tire Scrub: Placing the axles closer together and moving them rearward like our dual tandems relieves much of the stress and wear associated with tri-axle trailers built by other manufacturers.

Slipper Suspension: Multi-leaf springs and greasable equalizers are far superior to outdated eye to eye springs and shackles.

Hanger Bracing: Each suspension hanger point is braced according to axles manufactures recommended specifications.

EZ-Lube: Axles may be greased periodically with a grease gun without hub removal.

Brakes: Electric brakes on all axles provide more braking power than single axle brakes.

Wheels: 8 Lug, 16" Disc wheels are far superior to old demountable 14.5" MHU (Mobile Home Utility) rims of the past.

Radial Tires: 16" Radial tires is always and improvement over Bias ply tires.

Stable Ride: Low Profile and Wide Frame provide for a very stable platform for increased handling.

Great Balance: With the long balance point of the tri-axle suspension, load distribution and balance with proper hitch loading is easily achieved
