4 Axle Detachable Gooseneck Lowbed Trailer 3.65m Width

Front-end drive-on loading defines the heavy-haul efficiency of this 18.28m detachable gooseneck (RGN) low-bed semi-trailer. Powered by an independent diesel power station mounted directly on the gooseneck, the hydraulic decoupling system separates the neck from the trailer chassis in minutes. Once detached, the ultra-low cargo deck rests flat on the ground, creating a gentle, direct drive-on ramp. Large crawler cranes, heavy excavators, and drilling rigs load straight onto the well without climbing steep rear ramps or navigating rear axle clearances, significantly streamlining equipment turnaround times on industrial job sites.

Handling oversized machinery requires dynamic deck flexibility. While the main platform measures 3.05m wide, integrated 30cm heavy-duty swing-out outriggers extend the effective loading width to 3.65m on demand. This enables safe, balanced transport of wide-track construction equipment while keeping standard dimensions for empty highway repositioning. The sunken well platform minimizes center of gravity, delivering superior lateral stability across corners and high-crown corridors while easily clearing low bridges and highway toll barriers.

The running gear is engineered for extreme payload reliability. Four 20-ton rated heavy-duty axles paired with reinforced multi-leaf mechanical suspension distribute concentrated equipment tonnage smoothly across the chassis. 1200R20 heavy-duty tube tires provide ample ground clearance, high load capacity, and rugged puncture resistance across quarry access tracks and unpaved infrastructure projects.

As a detachable gooseneck lowbed trailer manufacturer running our own China heavy haul trailer production line, the high-tensile steel main frame, hydraulic locking pins, and outrigger assemblies are fabricated in-house at LUYI Vehicle. Ordering factory direct gives fleet owners complete engineering customization over well length, deck height, outrigger spacing, and axle ratings matched to specialized regional haulage permits.
