The Double A GHB Series Hydraulic Dovetail Gooseneck Trailer is an industrial-grade, commercial transport powerhouse. Moving far away from light-duty utility units, this flatbed deckover is custom-engineered for hotshot haulers, heavy-equipment operators, and agricultural teams who need to move massive payloads like excavators, full-sized tractors, or multiple vehicles simultaneously.

The defining evolution of the GHB model is its fully integrated Engineered Neck and Main Beam design, which replaces traditional standard I-beams with a high-strength, robotically optimized steel chassis that maximizes carrying capacity while dropping unnecessary deadweight.

Optimized Engineered Neck & Main Beam Construction

Instead of using standard off-the-shelf structural steel, Double A custom-manufactures their own tapered, engineered main frames and gooseneck risers.

• The Benefit: By mathematically calculating exactly where a trailer experiences the most structural stress, the engineered beam is built taller and thicker in high-fatigue areas (like the neck-to-frame transition) and tapered down where less material is needed. This yields a frame that is dramatically more resilient to "tongue twist" and structural sag under maximum payload, while remaining light enough to maximize your net legal payload.

12-Foot Lift-and-Carry Hydraulic Dovetail

The rear section features a massive, heavy-duty 12-foot hydraulic tail controlled via an on-board pump system and remote.

• The Benefit: No more flipping heavy manual ramps. At the push of a button, the entire rear 12 feet of the deck lowers smoothly to create an ultra-low, 12-degree approach angle, allowing low-clearance machinery to drive straight on. Even better, it features a true 10,000 lb. lift-and-carry capacity, meaning you can legally park heavy trucks or equipment directly on the dovetail during transport, expanding your total useable deck space to the absolute maximum.

Dual-Stage High-Capacity Running Gear Options

The GHB series is configured to order with elite commercial-tier wheel and axle packages.

• The Benefit: Available in Tandem-Dual (2 axles) or Triple-Dual (3 axles) configurations utilizing premium 10,000 lb. to 12,000 lb. Lippert or Dexter oil-bath axles, delivering a crushing 25,000 lb. to 45,000 lb. GVWR. Dual wheels on heavy-duty 14-ply or 17.5" radial tires ensure flat-tire redundancy and maximum highway footprint stability at 70+ MPH.

Integrated Torque Tube & Close-Center Crossmembers

Running directly down the center belly of the frame is a structural torque tube, supported by 3" junior I-beams spaced on tight 12" to 16" centers.

• The Benefit: The thick-wall circular torque tube completely stops the trailer from "corkscrewing" or swaying under off-center loading. The tight spacing of the sub-frame crossmembers ensures that heavy steel tracks or solid-rubber industrial tires won't puncture or bow the floor boards between the frame rails.

Dual Speed Jacks (Hydraulic Jacks Optional Upgrade)

The nose of the trailer features heavy-duty dual 25,000 lb. two-speed landing legs.

• The Benefit: Standard configurations give you massive mechanical advantage to lift a fully loaded trailer off a truck hitch with ease. Upgrading to dual fully hydraulic jacks hooks the landing gear straight into the on-board pump system, allowing you to unhitch and level a maximum-weight load in seconds at the push of a switch.

Lockable Front Toolbox & External Rub Rails

Every aspect of vehicle securing and operator convenience is integrated into the structural steel.

• The Benefit: A full-width lockable cargo box is built directly between the neck upright risers to securely store giant transport chains, binders, and the hydraulic pump assembly. Externally, continuous 3/8" heavy-duty rub rails paired with deep stake pockets allow you to secure strap hooks or chain binders at any precise point down the entire length of the deck.

• GVWR: 25,000 lbs to 45,000 lbs (Heavy Commercial Class).

• Deck Dimensions: 102" Maximum Legal Width x 32' to 44' Total Lengths.

• Tail System: 12' Full-Width Hydraulic Dovetail with traction cleats.

• Running Gear: Dual or Triple Tandem Axles (10K, 12K, or 16K variants) with HDSS Adjustable Suspension.

• Brakes: Electric-over-Hydraulic Drum or Disc Brakes standard.

• Floor Type: 2" Heat-Treated Premium Wood Decking.

• Finish: Industrial-grade blast prep with premium baked powder coat armor.

• Zero Physical Loading Labor: Standard flip-over ramp trailers force you to lift 100+ lb steel chunks or slide heavy channels manually. The hydraulic tail handles 100% of the labor mechanics internally.

• The Ultimate Loading Safety Envelope: Because the entire 12 feet transitions smoothly to the ground, there is no "blind drop" or aggressive apex hill for your equipment to climb over. This completely eliminates the risk of heavy machines tipping backward or losing traction when loading in rain, ice, or mud.

• Unmatched Structural Efficiency: Moving up to an engineered beam layout gives you the frame strength of a massive industrial oilfield trailer without dragging around thousands of pounds of dead, unneeded raw steel weight on every trip.

The Double A GHB Hydraulic Dovetail Gooseneck is the premier tool for Commercial Hotshot Drivers, Construction Fleet Managers, Heavy Agricultural Haulers, and Industrial Equipment Rental Companies. It is engineered explicitly for professionals who demand a maximum-strength, zero-labor loading deckover that tracks like an arrow on the interstate and handles severe continuous payloads without breaking a sweat.
