New Trail King HDG Hydraulic Detachable Gooseneck Trailer for Sale

Our Hydraulic Detachable Gooseneck trailer has become the go-to choice for construction professionals with over two decades of being North America’s bestselling detachable lowboy trailer. It’s engineered to make unhooking, loading, unloading, and hooking up again a simple one-person operation. This trailer has dependable load-hauling strength, durability, and versatility that can stand up to any challenge—even “tough to scale” loads.

  • Adjustable Arched Gooseneck: The new arched design provides ample truck frame clearance, ever at the lowest king pin height setting.  The 5-position of optional 7-position gooseneck door adjustment allows for a full 6” 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
  • V-Shaped Guide: The V-shaped guide directs the gooseneck into position during hook-up, making the coupling process a quick easy one-person operation.  The guide rim above the pin hole further prevents the main pin from uncoupling during transit
  • 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
  • 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.  Heavy-duty pullout front outriggers provide extra strength at the pivot point where the weight is concentrated during loading.  Close-set outriggers at mid-deck prevent planks from tipping up when the load rolls over them.
  • Double-Hinged Ramp and Support Ledge: The 31” front loading ramps are double hinged 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.  Optional spring-assist ramps available
  • Knuckle and Boom Troughs, 3rd Lift Axle: Lowered cross members are covered with ¼” MF80 steel for a knuckle trough in the rear deck area.  Lowered cross members through the entire wheel area, including a lowered center section in the rear channel, are covered with 10-ga. Steel.  A third axle with lift is standard equipment on TK102HDG and TK110HDG models
  • One-Piece Construction: Trail King I-beams are constructed of one-piece web and flange material and welded on all four corners to seal and protect the seams from rust.  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
  • 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 the operator 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 and convenient
