Description

Description

With a 20′ deck, this design for a 10000 lbs flat deck trailer is ready for building.  (10,400 lbs to be more exact).  These blueprints have all the options and features of our Endurance Duty family of Deck-Over Trailer Plans.  The frame is structural steel, then you choose the rest.  Choose options like various sides, ramps, hitch style, deck style, and much more.  Even the options have options — like choices for ramp length and strength.  Build it the way you want it.  This trailer is tough by design because that’s what you’ll expect.

Tandem Axle, 10000 lbs Flat Deck Trailer Plans

There’s not much to substitute when you need a broad Flat Deck trailer.  This trailer spans the full legal limit of 8′ 6″ wide and includes a 20′ long deck.  Tandem Axles give 10,400 lbs capacity making this Deck-Over trailer perfect for many.

Since you want strength and options, that’s what these blueprints deliver.  For instance, our research shows many owners wish their ramps were a little longer or a little stronger — so we give you both.  And, the info to choose with a chart showing capacity by length so you can find your own sweet spot.  Again, it’s just one example of how these plans help you make the right trailer for you.

Giving you choices to build the way you want it is the Mechanical Elements way.  Designing for tough action, is all included, right down to the thickness of the rub rails for robust action.  The same is true throughout the trailer.  Since it’s from Mechanical Elements, these are things to expect.

Get the trailer plans, then customize them to fit your specific needs.

7000lb Deck-Over Trailer Plans Options
Some of the options.  Plank deck, 8.5′ Ramps, Perimeter Rub Rails and Stake Pockets, Front Stop Rail, Tongue Tray Storage (hard to see), Pivoting Tongue Jack, Adjustable Hitch, etc.  And that’s not all.  (16′ trailer shown.)

More About The Design Features

More About The Design Features

While the specifications are nice, here’s little more information to expound on the trailer features — 10,000 lbs Flat Deck Trailer.

  • * The trailer is 8 feet 6 inches wide (typical legal width limit), with a bed length of 20 feet 3.5 inches including the steel frame.  8’6″ width includes the rub rails.
  • Overall length with the tongue is 301 inches (a little over 25 feet) — which will vary a little with some options.
  • Trailer bed height will depend on design options.  Typical is ~35 inches, but will vary with tire size, spring shape, shims, load and other options.
  • 10,000 lbs max capacity (combined axle rating)* using tandem axles rated at 5200 lbs each.  Load capacity includes the trailer weight with all options.
  • While the suspension primary design is leaf springs, double eye style, with equalizer; Slipper type springs are also acceptable.  Not for independent torsion axles (see this article).
  • Trailer weight will vary depending on design options.  The 10K base flatbed trailer is in the 2100+ lbs range, which includes an estimate for axles and wheels, but without decking, sides or ramps.  Options like sides, decking choices, and all the other options will change the weight.
  • Many options are in the plans.  Here is a list, yet it does not include everything.
  • Deck options — both material, connection options, with or without the wheel covers, etc..
  • Build the standard flatbed, or choose on of the sides options — permanent or removable — also in the plans.  Sides options have variations, including options for tie-downs, rub rails, stake pockets, etc..
  • Ramps are an option — Choose ramps that slide in (and store) under the deck (or not), then choose the ramp length and capacity you need.
  • Design includes options for a raised front rail (or not), and a tongue tray for special carry (or not).
  • Choose a mounted toolbox, a tongue tray, spare tire, etc. are there for optional functionality.  Since some options are mutually exclusive, not all options are in the pictures here.

    Deck-Over Trailer Options
    While it can be made as a typical Deck-Over, these trailer plans include many options you won’t find in other blueprints.
    (20′ Trailer shown, others similar.)
  • The download package includes the full set of drawings along with illustrated instructions and CAD files for laser or water jet cutting of the tail plate and other option parts.
  • We provide the plans complete, the way we would want to receive them.  We think they are much more complete and more detailed than any of our competitors.
