Key Product Features & Advantages
Gooseneck & Detachable Mechanism
Detachable gooseneck (RGN) — The front neck can be removed hydraulically or mechanically, letting the deck drop to ground level for direct equipment drive-up.
Hydraulic neck option — Seamless and efficient detachment/attachment using tractor wet-kit or hydraulic pump; quick locking pins, safety locks, and secure pins to ensure stable connection.
Mechanical neck option — Simpler structure with manual locking (pins) for customers preferring low maintenance or remote settings.
Low neck / ultra-low cargo table — The gooseneck design ensures the center-of-gravity is very low, thus enhancing stability and enabling transport of tall loads.
Structural & Coating Advantages
High-strength steel frame and I-beam construction — Main beam, side rails, cross members, and necks use high-grade, high-yield structural steel to resist bending and fatigue.
Anti-corrosion surface treatment & paint / coating — Multi-stage surface preparation (sandblasting, phosphating, primer, intermediate coat, topcoat) or optional powder-coat finish.
Axles, Wheels & Tires
High-capacity axles — 3 axles rated typically 25,000 lb (or higher, depending on spec) each, often with third-axle lift function.
Lift axle (optional) — The third axle can be lifted when under light load to reduce tire wear and improve maneuverability.
Wheel & rim spec — Standard steel disc rims 8.25″ × 22.5, hub-piloted, with 10-bolt pattern.
Tires — Twelve high-quality radial tires (e.g. 275/70R22.5 or other heavy-duty radial spec) to balance load, wear, and stability.
Braking system — Full air brakes (16.5″ × 7.0″ or equivalent) on all axles, auto slack adjusters, spring parking brake on one axis, and ABS (2S1M or more) configuration for safety in braking.

Frequently Asked Questions (FAQ)
Q1: What is the maximum payload / load capacity of a 3-axle RGN lowbed trailer?
A1: It depends on the design, axle ratings, and regulatory limits. A well-engineered 3-axle RGN trailer can carry 50 to 80+ tons
Q2: Why choose a removable gooseneck (RGN) design?
A2: The RGN design allows the front of the trailer to drop to ground level (after detaching the gooseneck), enabling self-powered equipment to drive directly onto the deck without external ramps. This saves time, cost, and enhances safety.
Q3: Hydraulic detachable vs mechanical detachable gooseneck — which is better?
Hydraulic detachable: Faster, easier, more convenient for frequent operations; but requires hydraulic system, maintenance of seals, and a hydraulic source (wet-line).
Mechanical detachable: Simpler structure, less maintenance, lower cost, but slower and more manual labor needed.
Choice depends on your operational frequency, maintenance capacity, and budget. ZW Group supports both options
