Detachable Gooseneck Lowboy Semi-Trailer - Hydraulic Removable Gooseneck Heavy Haul Trailer

Prime Mover detachable gooseneck lowboy semi-trailer features hydraulic quick disassembly design, ultra-low deck height and super heavy load capacity. Ideal for transporting excavators, cranes, rollers and oversized engineering equipment. Full custom size, global certification and complete after-sales support.

Product Brief Introduction

The detachable gooseneck lowboy semi-trailer, also known as RGN (Removable Gooseneck) lowbed trailer, is a professional heavy-duty and oversized cargo transportation equipment independently developed by Prime Mover Industries. Different from traditional fixed gooseneck low trailers, this model adopts a fully hydraulic detachable front gooseneck structure, realizing free separation and docking between the gooseneck and the low-load platform. After disassembling the gooseneck, the front end of the trailer drops to the ground to form a natural ultra-flat ramp, allowing tracked and wheeled equipment to drive on and off directly without auxiliary cranes or loading ramps.

Equipped with multi-axle balanced load-bearing design and high-tensile steel integral frame, this trailer features ultra-low chassis height, strong anti-torsion capacity and stable heavy-load performance. It perfectly solves the transportation difficulties of ultra-high, ultra-wide and super-heavy engineering machinery and special equipment, and is widely used in global engineering construction, mine exploitation, road infrastructure and cross-border oversized cargo transportation. It is the most mainstream and efficient heavy-haul transportation model in the international logistics market.

Core Product Advantages

Hydraulic Quick Detachable Gooseneck, Zero Auxiliary Equipment

The core advantage lies in the fully hydraulic automatic separation function of the gooseneck. The whole disassembly and docking process only takes 5–10 minutes without cranes, forklifts or other auxiliary equipment. After separation, the front platform is grounded to form a gentle slope, realizing self-driving loading and unloading of tracked excavators, bulldozers and wheeled machinery, which greatly improves operation efficiency and saves loading and unloading costs.

Ultra-Low Deck Design, Strong Traffic Passability

The ultra-low platform height effectively reduces the overall height of loaded cargo, solving the height limit problem of oversized mechanical equipment during highway, bridge and tunnel transportation. It avoids frequent road approval and detour problems, greatly improving the pass rate of oversized cargo transportation and reducing transportation time cost.

Super Strong Load-Bearing & Anti-Deformation Structure

The main frame adopts integral deepened I-beam full welding process, with dense cross beam reinforcement structure. The multi-axle balanced load distribution design makes the force uniform, effectively resisting torsion and bending deformation caused by long-term super-heavy load. The whole vehicle undergoes shot blasting and multi-layer anti-corrosion painting, adapting to harsh environments such as mines, construction sites and coastal areas, with long service life.

High Safety & Stable Heavy-Load Driving

Low center of gravity design greatly reduces vehicle rolling risk during high-speed driving, sharp turning and complex road transportation. Equipped with high-performance ABS/EBS braking system and reinforced suspension, the trailer runs stably under full load. Multiple groups of heavy-duty lashing holes and anti-skid platform ensure firm fixation of heavy machinery without displacement or sliding.

High Flexibility & Wide Adaptability

Support free switching between detached loading and integrated transportation modes. It can transport not only large engineering machinery, but also steel structures, wind power accessories, bridge components and other oversized heavy cargo. Customizable lengthening, widening and lifting axle functions meet diversified transportation demands of different working conditions.

Application Fields

Engineering Machinery Transportation

It is the preferred equipment for long-distance transfer of large construction machinery, including excavators, bulldozers, road rollers, pavers, loaders and cranes. The self-loading function efficiently meets the frequent equipment transfer demands of road construction, bridge engineering and municipal projects.

Oversized Industrial Equipment Haulage

Suitable for transporting large generator sets, industrial presses, wind power equipment, transformer equipment and other ultra-high and ultra-heavy industrial equipment. The ultra-low platform effectively avoids height limit restrictions and solves the transportation pain points of special oversized cargo.

Mine & Mining Equipment Logistics

Adapt to harsh mine road conditions, transporting large mining trucks, drilling rigs, crushing equipment and mining accessories. The rugged and durable structure resists bumpy road impact and meets high-intensity heavy-load operation demands.

Cross-Border Oversized Cargo Transportation

Fully compliant with highway transportation standards in Africa, the Middle East, Southeast Asia and other regions. It is widely used for cross-border engineering project equipment delivery and oversized heavy cargo logistics, with high passing efficiency and strong regional adaptability.

Gooseneck Disassembly & Reinstallation Operation Process

Step 1: Preparatory Work

Park the tractor and trailer on a flat and hard road surface, tighten the hand brake, place anti-skid triangular blocks at the tires, and check the hydraulic oil level and pipeline sealing of the gooseneck system to ensure no leakage.

Step 2: Hydraulic Loosening & Separation

Start the hydraulic system, slowly lift the gooseneck to unload the gravity of the tractor head, open the fixed locking pin, and continuously lower the gooseneck until the front end of the low platform contacts the ground to form a stable loading ramp.

Step 3: Equipment Loading

Guide the tracked or wheeled equipment to slowly drive onto the low platform, adjust the parking position, and fix the equipment firmly through lashing belts and fixed holes to ensure no shaking or displacement.

Step 4: Gooseneck Docking & Resetting

Drive the tractor backward to align with the gooseneck interface, start the hydraulic system to lift the front platform, complete accurate docking with the tractor fifth wheel, insert the locking pin, and confirm full fastening and no gap.

Step 5: Post-Operation Inspection

Check the hydraulic pipeline pressure, locking structure firmness and braking system sensitivity, and confirm that all parts are normal before formal driving transportation.

Daily Maintenance & Upkeep Specifications

Daily Inspection Before Driving

Check the gooseneck hydraulic system for oil leakage, pipeline aging and insufficient oil level; verify the locking pin flexibility and fastening degree; inspect tire pressure, tread wear and axle operation status; test brake and ABS system response; clean platform sundries and check anti-slip performance.

Regular Cycle Maintenance

• Every 5,000km: Lubricate gooseneck rotating shaft, axle bearings and landing gear gears; tighten all chassis and hydraulic fixing bolts; replace hydraulic filter element.
• Every 20,000km: Replace hydraulic oil comprehensively; inspect suspension spring fatigue and brake pad wear; calibrate multi-axle balance and braking consistency; detect frame welding seams for hidden cracks.
• Every 50,000km: Conduct overall chassis anti-rust maintenance, overhaul hydraulic cylinder and valve group, replace aging sealing parts, and complete full vehicle performance calibration.

Forbidden Operation Rules

It is forbidden to disassemble the gooseneck on uneven soft ground; do not overload beyond the rated load for a long time; avoid sharp turning and emergency braking with full-load equipment; do not expose the hydraulic system to rain and dust for a long time to prevent pipeline blockage and oil deterioration.
