Front Access Panel
The front access panel offers easy access for connecting hydraulic, air and electrical lines. The panel may also be opened for internal maintenance or repair simply by loosening four bolts.
Even “dead” equipment can be loaded with ease with the standard 20,000-lb. winch with level wind (mounted above the king pin). Winch guard and 65' cable with locking safety hook are also standard.
Flexible Protective Track
Special flexible track encases and protects traveling air and electrical lines from pinching or abrasion that could lead to premature failure.
Strength and Protection
A protective panel on the underside of the gooseneck shields the hydraulic valves from road grime and debris, resulting in reduced maintenance and longer life. And to prevent cracking and provide extra strength, the gooseneck is reinforced with a half-moon gusset and a brace that runs the full depth of the beam.
Upper Deck Ramp
The 10' hydraulic recessed ramp to the upper deck provides a 10° load angle. A special locking mechanism (see inset) ensures that the upper deck ramp stays in place during loading, even if the hydraulics should fail.
Protected Electrical System
The HST features rubbermounted, shock-proof, sealed lights and rubber grommets wherever wiring runs through the frame for a longer, troublefree, low-maintenance performance life.
As the axles travel, the dovetail deck rides securely on 5"-wide rollers that are centered on the main beams. This prevents damage to the flange, a common problem in offset designs.
Low Load Angle
With wheels moved forward, the tail can be lowered to a 10° load angle. The resulting transition from the tail to the deck at the hinge point allows low ground clearance equipment, such as scissor lifts and manlifts, to be loaded with ease.
Twelve-Beam Approach Plate
Two outside I-beams provide the extra strength necessary to prevent “peeling off” the edge of the ramp during loading. Ten formed beams in between provide solid support across the whole width of the approach plate.
Trail King 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 is installed for complete protection from the elements – even in places you can’t see.
Because the wheels are positioned farther back on the trailer, “scalablity” is improved. What’s more, the hydraulic cylinder is completely closed when the trailer is in the transport position, thereby protecting the cylinder rod from road debris when the trailer is moving.
Flip Tail Lock
When the trailer is in the transport position, the flip tail cannot settle to the ground – even in the event of hydraulic failure – thanks to the automatic flip tail lock.
