8.5′ x 20′ – 14/16,000 lbs Deck-Over Trailer Plans

Description

This is a heavy duty deck-over trailer.  At 14K (or option for 16K deck-over) at 20′ deck length, this trailer is a workhorse.  The plans are fully engineered, with Step-by-Step instructions, so it is ready to build.  Like all our Deck-Over trailers, these blueprints have many options and extra features you won’t find with our competitors.

The frame is engineered with structural steel – including the option for 14,000 lbs or 16,000 lbs total capacity.  This trailer is tough by design, with the engineering to back it up.  We give the engineering, then you choose the functional options you want.

Choose options like ramps, hitch, deck material, sides, and more.  And, many options have options – like choices for ramp length and strength.  Need ramps a little longer? or a little stronger?  The plans give a ramp design, with options for length and strength, so you can find your sweet spot.

There are options for decking material, rear struts, front bar, storage, and more.  Build it the way you want it.

Heavy Duty 14K or 16K Deck-Over Trailer Plans

When you need an Endurance Duty deck-over trailer, there is not much else to substitute.  Yet, this trailer is not just heavy duty, there is a lot of finesse in the design.  The deck is 8′ 6″ wide by 20′ long with tandem axles and many choices for functions.

The deck is as low as practical, even coming up under the deck with wheel covers to minimize deck height while giving space for wheel and suspension movement.

A tongue tray is also an option, as well as fold-up tail struts to support the deck when loading heavy things – like a tractor up the ramps.

In researching deck-over trailers we found many niggly things some owners would change.  That brings us to give you choices, then you can make the decisions.  Choices let you build it the way you want it.  Something you can expect from Mechanical Elements.

Specifications

8.5′ x 20′ – 14/16,000 lbs Deck-Over Trailer Plans

• 16K max at 8’6″ x 20′ nominal deck size.
• Option for 14,000 lbs axle capacity or 16,000 lbs capacity (including the trailer and the payload).
• Tandem axles with slipper style leaf springs.

• Welded Steel Construction has rectangular tube main beams for max torsional stability, then channel, angle and flat in other areas.
• Some parts, like the tail plate and wheel covers are cut from sheet steel.  (We give you the files to have them CNC cut out.)
• While the main design is a traditional Deck-Over trailer, plans also include many options.
  (Something you just don’t get with other trailer plans.)
• Approximate base trailer weight ~ 3000 lbs (w/o Ramps, Decking, or Sides).  Options and variations will increase weight.  The 16K deck-over is heavier.
• Final trailer weight will depend on your choices, like decking material, sides, extras, capacity, storage, and more.
• The trailer is Endurance Duty, so it is tough, but not overdone.
• Instructions explain the build, step by step, with hints to customize for many specific needs.
• The download is a Zip file with full drawings, instructions, extra illustrations, and special part files.  Just save them to your computer.
• Fully Engineered design by Synthesis Engineering Services.

More About The Design Features

Here is a little more information to expound on the trailer feature specifications. This is the 16K by 20′ length deck.

• * The trailer is 8′ 6″ wide (typical legal limit), with a 20′ 3.5″ bed length (including the frame).  8′ 6″ width includes the rub rails.
• Overall length with the tongue is 302″ (a little over 25 feet) — will vary with some options.
• Trailer bed height depends on options.  Typical is ~35″ to 36″, but varies with tire size, spring shape, shims, load, etc..
• Option for 14K or 16K (16,000 lbs) max capacity (combined axle rating)* using tandem axles — rated at 7000 lbs or 8000 lbs each.  Load capacity includes the trailer weight with all options, and the load.
• Of course, the suspension is heavy leaf springs, slipper style, with equalizer.  Eye-Eye springs with similar spacing and equalizer can substitute.  Not made for torsion axles (See this article).
• Trailer weight depends on options.  The base trailer plus decking choice, sides, ramps, accessories, etc..
• Plans have many options.  Here is a partial list.
• Deck options – material, connection options, with or without the wheel covers, etc..
• Build the standard flatbed, or choose sides – permanent or removable.  And, sides options have options like 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 ramp length and capacity.  The engineering is there to help you choose.
• Design has options for a raised front rail (or not), and a tongue tray for special tools (or not).
• Choose a mounted toolbox, spare tire, etc. for functionality.  Since some options are mutually exclusive, not all are in the pictures here.

  

• Blueprints include the full set of drawings, illustrated instructions, plus CAD files for laser or water jet cutting the tail plate and special parts.
• We give plans the way we would want to receive them.  Complete, with details and lots of info.  Some you will use, some not, but we give you choices.
