Fleetneck Engineered Beam Trailer

Lighter – Stronger – Engineered to Deliver

Diamond C is forging a new era in trailer design with our Engineered Beam Technology. We design, engineer, and optimize our own U.S. Patent Protected I-Beams to fit each model. Our Engineered Beam GOOSENECK trailers are stronger yet lighter, featuring the best strength-to-weight ratios of any steel frame gooseneck on the road.

 

But first, a little history…

The year was 2015, and we had been building gooseneck trailers just like the rest of the industry for the past 30 years. We purchased standard I-Beams and sliced and diced them and added reinforcement to make strong trailers out of them. While we had always been proud of our gooseneck trailers, we came to a place of unrest. We knew that there had to be a better way.

We started studying the strength dynamics of I-Beams and quickly turned to flat-bed semi-trailers for inspiration. For decades the semi-trailer manufacturers have been building their own I-Beams, custom to each trailer configuration. They realized long ago that standard beams were not the best solution for the strongest, lightest trailer frames. They needed taller beams considering the span of the frames without the excess weight that comes with taller standard beams.

The same principles clearly applied to gooseneck trailer framing so we set out to design, engineer, and build our own I-beams.

After nearly three years of research and development, the Fleetneck Engineered Beam product line was the result. We proudly debuted the brand new Engineered Beam goosenecks at the 2017 NATDA Trade Show and took the flatbed gooseneck trailer world by surprise. In 2019 we were awarded a U.S. Patent for our efforts.

We now have an almost infinite control over the shape of the beams. We’re able to optimize the performance of the steel by putting it to work where we need it most. No dead weight. No added reinforcements needed. We’re able to build contours into the beams that optimize the total design and functionality, from dovetails to deck-height. Our beams are the tallest and strongest in gooseneck trailers, with the best strength-to-weight ratios on the road.

Fast forward to 2020, and we are now bringing the technology behind the Engineered Beam design to the rest of our product lineup, starting with Dump and Equipment trailers. Diamond C has always been a pioneer in trailer innovation and a leader in pushing the industry forwards, and our beam design is certainly no exception to that. Watch this space for more news and upgrades, and in the meantime, keep scrolling to find out more about how our patented beam design helps your trailer be one of the best in the world.

 

Features

Engineered Beams

We engineer the I-Beams, optimize them, and build them for each trailer configuration, just like the semi-trailer manufacturers have been doing for decades.

Our engineered I-Beam frames are taller, stronger, and lighter than the industry standard for deck-over and flatbed trailers. Depending on the model, the beams on our GOOSENECK trailers range from 14-18″ tall, and the beams on our compatible DUMP and EQUIPMENT trailer models range from 10-12″ tall. Standard steel will buckle and break at 36 ksi, and we didn’t compromise there either; our beams are built using steel rated at 50 ksi minimum, so it springs back no matter what load you put on it.

The Camber

The deck and frame have a slight camber when not loaded. When loaded, it flexes as necessary to level but never sags like in traditional goosenecks.

Engineered Neck

You’ll notice our goosenecks look very different than normal flatbed gooseneck trailer necks do. This is by design. Our curved 12″ Engineered Neck design distributes force throughout the neck so there is no concentration of stress in the corners like on traditional goosenecks. These Engineered Necks come standard on any gooseneck FLEETNECK series trailer, and well as on most of our bumper-pull trailers featuring our optional GOOSENECK PACKAGE upgrade.
