Looking at a detachable lowboy gooseneck trailer? A detachable lowboy is the heaviest-duty gooseneck on the market — the front gooseneck section unhitches and lowers the deck flat to the ground for a zero-degree load angle. Used to haul excavators, large dozers, and any heavy equipment that can’t climb ramps. This guide explains how detachable lowboys work, ranks the major brands, and breaks down 2026 pricing. For broader gooseneck buying guidance, see our gooseneck trailers buyer’s guide.
What Is a Detachable Lowboy Gooseneck Trailer?
The gooseneck section (the part that hooks into your truck bed) detaches mechanically (manually) or hydraulically (powered). Once detached, the front of the deck lowers to the ground for loading. Equipment drives or rolls onto the deck at near-zero angle, then the gooseneck reattaches and the deck rises for transit.
Total trailer length: 30–50 feet typical. GVWR: 30,000–60,000 lbs. Class III hitch only. Best for tracked equipment 12,000–40,000+ lbs.
Detachable vs Fixed-Neck Gooseneck
A fixed-neck gooseneck (standard configuration) requires ramps. A detachable lowboy lays flat — dramatically reduces loading risk for tracked equipment and very heavy machinery. The trade-off is cost and complexity.
| Factor | Detachable Lowboy | Fixed-Neck Gooseneck |
|---|---|---|
| Load angle | Zero degrees | 10–16 degrees on ramps |
| 2026 price (new) | $60K–$180K | $25K–$60K |
| GVWR range | 30K–60K+ | 14K–40K |
| Best for | Excavators, dozers | Skid steers, equipment under 30K |
Top Detachable Lowboy Brands

Trail King — Iowa-built, equally premium, slightly different mechanical detach design.
Eager Beaver — commercial-grade, slightly less expensive, popular with municipal fleets.
XL Specialized — Ohio-built, specializes in custom configurations.
Hydraulic vs Mechanical Detachable
Hydraulic detachable: fastest setup (2–3 minutes), works alone, premium price (+$15K–$30K over mechanical). Mechanical: slower (10–20 minutes), often requires two people, lower cost, fewer hydraulic failure points.
