Why Choose Load King Folding Gooseneck Trailers?
Load King invented the E-Z Fold gooseneck in 1966 and continues to lead with innovative, operator-focused designs:
Effortless Folding Design – Parallel-link, hydraulic (DFP) or mechanical (DFM) folding gooseneck prevents binding and allows quick drive-on loading even without winch.
High Load Capacities – From 40-ton to 80,000 lb concentrated loads, accommodating a wide range of heavy machinery needs.
Proven Durability – Full-depth perimeter frames, 100K/80K PSI yield steel, cambered deck beams, and perimeter crossmembers support heavy, narrow loads.
Field-Level Hook-Up – Hydraulic side-to-side leveling, multiple fifth-wheel settings, front lift eye, and alignment guides ensure hooking up on uneven terrain is quick and accurate.
Long-Lasting Construction – Ground-bearing hydraulics reduce stress, bolted board ends extend deck life, and deep crossmembers preserve structural strength.
Key Benefits
Fast, One-Person Setup – Power-fold or manual neck lets operators load without cranes or external winches.
Terrain Flexibility – Hydraulic leveling and adjustable fifth-wheel positions ensure even hook-up on uneven surfaces.
Heavy-Duty Performance – High-capacity axles, sturdy frames, and reinforced decks deliver reliable load stability.
Proven Longevity – Ground-bearing systems, strong crossmembers, and durable materials mean these trailers last decades.
Specialized Options – Includes rail-ready models and configurations suited for tracked equipment and heavy machinery.
Models range from 40‑ton (80,000 lb) up to 50‑ton and 45‑ton configurations, with hydraulic folding options for each capacity.
No. Folding gooseneck trailers feature power-fold or mechanical necks that allow self-contained drive-on loading without cranes.
Yes—built-in hydraulic side-to-side leveling and multiple fifth-wheel height options support uneven terrain alignment.
Ground-bearing hydraulics reduce frame stress, perimeter frames add rigidity, bolted Apitong boards resist wear, and 18″ crossmembers provide load support.
Yes—models 403‑4 DFPR (hydraulic) and DFMR (mechanical) include rail tracks and recessed configurations for easy loading of rail equipment.
