A removable gooseneck (RGN) trailer detaches its front section and lowers to the ground so tall or low-clearance machinery can be driven straight onto the deck. CHENLU builds 3- and 4-axle RGN trailers rated 30-100 tons, factory-direct from a China-based manufacturer exporting to 30+ countries.
A removable gooseneck (RGN) trailer, also called a detachable gooseneck trailer, is a heavy-haul semi-trailer whose gooseneck — the front section that connects to the truck's fifth wheel — can be hydraulically unpinned and lowered to the ground. This turns the front of the deck into a drive-on ramp, letting equipment load or unload under its own power instead of climbing rear ramps.

"Rated load capacity" is the trailer's designed carrying capacity under standard conditions, not a guaranteed payload for every route. Available capacity depends on axle configuration, local road regulations, and final engineering confirmation. Need a different tonnage or axle count? Send us your cargo weight and dimensions for a custom configuration.
RGN trailers are typically built as either a single-drop (step deck) or double-drop (lowboy-style) design. The lower the well, the more overhead clearance is available for tall cargo — but always confirm exact deck height against your local bridge and road clearance regulations before shipping.
One deck drop behind the gooseneck. Good general-purpose clearance for most construction equipment.
A second, lower well between the axle groups — the configuration most RGN heavy-haul trailers use for maximum overhead clearance.
Clearance figures are general industry reference points, not a guaranteed spec for every unit — actual usable height depends on axle configuration, tire size, and local road regulations.
The sequence below is a general overview of how an RGN trailer loads, not a substitute for the official operating manual supplied with your trailer. Loading and unloading should only be performed by trained personnel.
Park the trailer on level, solid ground, apply the parking brakes, and place wheel chocks before detaching.
Check the hydraulic system is at operating pressure, then unlock the pins connecting the gooseneck to the main deck frame.
The hydraulic power unit lowers the front section, creating a ramp angle from the ground to the deck.
Tracked or wheeled machinery moves directly onto the deck under its own power, or is winched on if needed, under the guidance of a trained spotter.
The gooseneck is raised, re-pinned to the truck, and the pin engagement is visually confirmed before the load is chained down for transport.
Always follow the operating manual supplied with your trailer, confirm hydraulic pressure and pin lock-out before towing, and never load or unload without trained personnel present.
يعتمد عدد المحاور بشكل أساسي على وزن الحمولة، نظراً لأن كل مجموعة محاور لها حمولة مقدرة قصوى، وتحدد قوانين الطرق المحلية الحد الأقصى للوزن الإجمالي الإجمالي للتركيبة. استخدم هذه النقاط كنقاط انطلاق عامة، ثم تحقق منها وفقاً لحمولتك ومسارك المحددين:
Suited to lighter equipment and shorter machinery where total combination weight stays well within standard road limits.
The most common configuration for mid-size excavators, wheel loaders, and general construction machinery.
تزيد من قدرة تحمل المحاور للرافعات الأكبر حجماً ومعدات التعدين والمكونات الصناعية الأثقل.

| رقبة وزة قابلة للفصل (RGN) | Fixed Gooseneck Lowbed / Lowboy | |
|---|---|---|
| طريقة التحميل | تحميل أمامي — تنفصل رقبة الوزة وتنخفض إلى مستوى الأرض | تحميل خلفي عبر المنحدرات |
| الاستخدام الأنسب | الآلات المرتفعة أو ذات الخلوص الأرضي المنخفض التي لا تستطيع صعود المنحدرات الخلفية | Equipment that can be driven up rear ramps; general lowbed cargo |
| ارتفاع سطح السفينة | Typically lower once detached, for extra overhead clearance | Fixed deck height, no ground-level loading option |
| Mechanical complexity | يضيف نظام الفصل الهيدروليكي أجزاءً متحركة تتطلب الصيانة | هيكل ثابت أكثر بساطة، وتكاليف صيانة أقل عموماً |
| التكلفة المعتادة | Higher, due to the hydraulic gooseneck system | أكثر اقتصادية لاحتياجات النقل القياسية |
If your equipment can load from the rear and you don't need the detachable feature, our Lowboy / Lowbed Semi Trailer range is typically the more economical choice. For lighter, more compact loads, see our مقطورة معقوفة معقوفة قابلة للطي range.

CHENLU exports to more than 30 countries and manages the full process in-house, from technical consultation to after-sales support.
Our team helps you select the model, axle configuration, and customization options based on your cargo and, where you can share them, your local road regulations.
Production takes about 10-30 days after deposit, depending on trailer type and customization, with regular photo/video updates. Third-party inspections are welcome.
We arrange RO-RO, bulk vessel, container, or flat rack shipping with complete export documentation (commercial invoice, packing list, bill of lading, certificate of origin).
Operational guidance, maintenance manuals, remote technical support, and genuine spare parts (brake linings, air chambers, valves, lamps) ready for rapid dispatch.
Planning to bring an RGN trailer into a new market? Share your local axle-weight and height limits when you inquire, and our engineering team will confirm whether the standard build fits or a configuration change is needed.
CHENLU operates its own semi-trailer manufacturing base in China — not a trading company — with modern workshops, CNC cutting, and automated welding lines.
An RGN (removable gooseneck) trailer moves heavy or tall equipment that can't be loaded from behind a fixed-neck trailer. Detaching the gooseneck lowers the deck to the ground so equipment can be driven straight on — common for excavators, wheel loaders, drilling rigs, and similar low-clearance machinery.
RGN stands for Removable Gooseneck. It's a heavy-haul semi-trailer whose front section (the gooseneck) can be hydraulically detached and lowered, turning the deck into a drive-on ramp.
CHENLU RGN trailers are available in 3-axle (30-60 ton) and 4-axle (60-100 ton) configurations, with an 80-ton model as the standard build.
A standard lowboy has a fixed gooseneck and loads from the rear via ramps. An RGN's gooseneck detaches and lowers to the ground, allowing front-loading — better suited to taller or lower-clearance machinery.
Yes — 3-axle or 4-axle, 13/16/20-ton axle ratings, mechanical or air suspension, and a choice of tire/rim specification, configured to your typical cargo weight.
Production is typically 10-30 days after deposit depending on trailer type and customization. Ocean transit time depends on the destination port and is confirmed at inquiry.
