Features

New Arched Gooseneck Design
The new arched design provides ample truck frame clearance, even at the lowest king pin height setting. The gooseneck I-beam’s web, top flange, and bottom flange feature one-piece construction for exceptional strength and durability. Externally mounted gooseneck stirrups are easy to service/replace.

5-Position Gooseneck Door Adjustment
The five-position adjustment allows for a full 8" range of king pin height settings. The notched setting control bar for the control handle takes the guesswork out of setting the gooseneck doors in the desired position.

Safety Lock
When the gooseneck cylinder doors are closed in the transit position, a safety pin automatically locks the main pin in place so that it cannot jump out of the pin hole and accidentally disconnect the trailer.

V-Shaped Guide
The v-shaped guide directs the gooseneck into position during hookup, making the whole process a quick, easy one-person operation. The guide rim above the pin hole further prevents the main pin from jumping loose during transit.

Double-Hinged Ramp and Support Ledge
The 31" loading ramps are doublehinged and reinforced with a support ledge for added strength. Because both hinges rest on the ledge, even heavy track-type equipment can be loaded without risk of “peeling off” the loading ramp.

Front Outriggers
Heavy-duty pullout front outriggers (standard) provide extra strength at the pivot point where the weight is concentrated during the loading process. Spring-loaded stainless steel latches can be turned and locked in the open position, leaving both hands free to pull out or push in the outrigger.

Outrigger Construction
I-beam style outriggers are mounted on the top and bottom flange and span the entire width of the side beam for optimum strength and support. Removable pins allow outriggers to be easily removed. Close-set outriggers at mid-deck (standard) prevent planks from tipping up when load rolls over them.

Four-Beam Deck Design
The four-beam deck design can accommodate a wide range of loads, whether the weight is concentrated on the outside edges or in the middle of the trailer. The lightweight strength of Trail King’s four-beam design also means you haul less trailer, more payload.

One-Piece Construction
I-beams are constructed of one-piece web and flange material and welded on all four sides to seal and protect the seams from rust. Then the entire trailer is primed and painted with a two-component polyurethane primer and paint before decking and air, hydraulic, and electrical lines are installed for complete protection from the elements – even in places you can’t see.

Knuckle Trough, 3rd Lift Axle, Boom Trough
Lowered cross members covered with ¼" MF80 steel for a knuckle trough in the rear deck area are now standard. A third lift axle is now standard and, thanks to a new suspension system, lowered cross members through the entire wheel area, including a lowered center section in the rear channel, are also standard.

Adjustable Ride Height Control
Adjustable ride height control is standard, with the controls conveniently located near the rear tail channel.

D-Rings
The deck area features seven (7) pairs of heavy-duty bent-style D-rings which wrap around the flange to protect the flange and safety chains from damage. Two additional flat D-rings are mounted on top of the main beam top flanges in the rear wheel area.

Cross Members
The deck area features 10" I-beam cross members, with 4" stub cross members for 12" centers in the outer bays, for optimum load-hauling strength and no bowing of the decking.

Sealed Electrical System
Rubber-mounted LED lights are standard, as well as a sealed “plug and play” electrical system. Rubber grommets protect the wiring wherever it runs through the frame. And should you forget to disconnect the lines before detaching the gooseneck from the bed, a replaceable jumper cable between the neck and the deck makes replacing a damaged line easy.

Specifications

Trail King's Advantage Plus! Series Hydraulic Detachable Gooseneck (HDG) trailer features a new gooseneck design, as well as a long list of new standard equipment.

Of course, Trail King's detachable gooseneck system still includes self-lifting hydraulic cylinders, non-ground bearing design, and V-shaped alignment guide - features that have made Trail King HDG trailers the #1 selling detachables on the market for over 20 years. Thanks to these outstanding features, detaching, loading/unloading, and hook-up are all quick, easy, one-person operations.

But now, the Advantage Plus! Series HDG also features a new 5-position gooseneck door adjustment that allows for a full 8" range of king pin height settings, plus a notched setting control bar to take the guesswork out of setting the gooseneck doors in the desired position. What's more, the new "arched" design of the gooseneck provides ample truck frame clearance, even when set at the lowest king pin height.

Also new on the Advantage Plus! HDG are the heavy-duty pullout front outriggers. Not only do these outriggers provide extra strength at the pivot point where weight is concentrated during the loading/unloading process but, because they are built right into the frame, there's no need to lift them on and off, or store them elsewhere when not in use. What's more, spring-loaded stainless steel latches can be turned and locked open, leaving both hands free to pull out or push in the outriggers. In addition, close-set outriggers at mid-deck to prevent planks from tipping up as the load rolls over them are now also standard.

Best of all, many other features that were previously only available as add-on options are now standard equipment on the Advantage Plus! HDG, including:

  • Covered knuckle trough in the rear deck - standard.
  • Covered boom trough in the wheel area - standard.
  • Third lift axle - standard.
  • Adjustable ride height control, with controls conveniently located near the rear tail channel - standard.
  • 10" I-beam cross members, with 4" stub cross members for 12" centers in the outer bays - standard.
  • LED lights and a sealed "plug and play" electrical system - standard.
  • Heavy-duty bent-style D-rings (7 pairs) - standard.

The Advantage Plus! Series Hydraulic Detachable Gooseneck trailer is available in 35-, 51-, and 55-ton capacities.
