Factory views of the detachable gooseneck, low loading deck and four-axle rear group. The quotation lists the equipment included with the order.
100 Ton 4 Axle Detachable Gooseneck Lowbed Trailer
This four-axle lowbed is configured for excavators, mining machinery and other heavy equipment loaded from the front. The gooseneck separates from the main deck, giving tracked or wheeled machines a direct loading path onto the low platform.
This configuration has an 8,860 mm main deck, a 3,500 mm overall width and a 18000 mm overall length. The four axles are arranged at 1,310 mm centres.
Also include the destination country or port so we can check deck fit, load position, tractor connection and the final rated configuration.
Why This 100 Ton Four-Axle Lowbed Uses a Detachable Gooseneck
The detachable neck is mainly about loading. It gives the machine a front entry onto the low deck, while the deck size and four-axle group are matched to the equipment, tractor and route.
Load Heavy Equipment from the Front
The gooseneck separates from the main deck for front loading. Excavators and other tracked machines can approach the low platform without travelling over the rear axle area.
Plan the Load Across Four Axles
The four-axle group provides more positions for distributing trailer and cargo weight. The final axle loads depend on the machine weight, centre of gravity, deck position and kingpin load.
Use the Deck Space for a Larger Machine
This configuration has an 8,860 mm main deck and a 3,500 mm overall width. Check the machine footprint, transport height and permitted route width before ordering.
How We Build This Four-Axle Detachable Gooseneck Lowbed
A typical build moves from the lowbed frame to the detachable gooseneck, four-axle running gear and final assembly. The work follows the confirmed order configuration at each stage.
Build the Main Frame and Low Deck
The main beams, cross-members and deck sections are cut, positioned and assembled to the ordered dimensions.
Fit the Detachable Gooseneck
The neck, front connection and operating components are installed and aligned with the main deck.
Install the Four-Axle Running Gear
The axles, suspension, brake lines and electrical wiring are fitted after the frame assembly is complete.
Complete Assembly and Final Checks
The deck surface, paint and ordered fittings are completed before dimensions, connections, braking and lighting are checked.

FAQ
Find practical answers about the four-axle detachable gooseneck trailer, payload review, loading method and configuration requirements.
What cargo is a four-axle detachable gooseneck trailer designed for? +
This four-axle configuration is designed for heavy, self-propelled machinery from 100 t — large tracked excavators, mining equipment, bulldozers, graders and other construction or industrial machines that can drive under their own power.
It is also used for non-self-propelled oversized cargo where axle-load limits rule out a three-axle layout. The right fit depends on the machine's operating weight, overall dimensions, track width and loading method.
When should I choose a four-axle RGN over a three-axle configuration? +
A four-axle layout is typically chosen when the cargo weight pushes per-axle load beyond the limits of a three-axle arrangement on the destination route, or when the cargo is large enough that a longer wheelbase provides better deck stability.
If your cargo weight, route axle-load limits or equipment dimensions place a three-axle layout under pressure, send the details for a four-axle configuration review.
What is the rated payload for this four-axle trailer? +
The design payload starts from 100 t. The actual permitted payload for your specific cargo and route depends on the destination axle-load regulations and the confirmed axle spacing from the approved drawing.
Four BPW 18T axles are fitted as standard. Send your cargo weight, destination country and known route conditions to receive a configuration proposal with a defined payload scope.
What gooseneck detachment system is fitted, and how is it operated? +
A hydraulic detachment system is fitted, powered by a Changchai 13.5 kW single-cylinder unit using ISO 68 hydraulic oil.
A remote control is included as standard, allowing the operator to manage gooseneck release and reconnection from a safe working distance. The full operating procedure is supplied with the trailer.
What axles and suspension are fitted as standard? +
Four BPW 18T widened axles are fitted as standard with export English-standard marking. Axle spacing is 1,310 / 1,310 / 1,310 mm across the rear three axles.
The suspension is a mechanical inverted leaf-spring system with 120 × 160 × 10-leaf packs, 6 assemblies and wide-type reinforcement. Air suspension is available as an option subject to engineering confirmation.
What are the working platform dimensions? +
Working platform length: 12,680 mm.
Working platform width: 3,500 mm. Outer trailer width: 4,300 mm. Loading platform height: 900 mm, with no pre-camber. Gooseneck height: 1,550 mm.
These values are from the approved engineering drawing and are subject to the actual product produced. Confirm final dimensions from the drawing before production begins.
What braking system is fitted? Is ABS available? +
Air brake is standard with 8 FUWA dual-diaphragm chambers and a WABCO valve. The system is configured for the tractor interface and destination market.
ABS is not standard on this configuration but is available as an option. Confirm the required ABS standard and brake-system interface for your destination market and tractor at the quotation stage.
