10-Axle 100-Ton Extendable Lowbed Semi-Trailer for Oversized Machinery Transport

Key Applications

The LUYI LY9400GFL is intended for transport assignments where an ordinary three-axle or four-axle lowbed trailer does not provide enough deck length, load distribution or structural reserve. The 10-axle layout is particularly relevant when the cargo has a high gross weight, a concentrated center of gravity or an irregular footprint that must be supported across a longer loading area.

Typical cargo includes large excavators, bulldozers, crawler machinery, mining crushers, drilling equipment, combine harvesters, industrial boilers, generator sets, transformers, steel structures, bridge components and tunnel-construction equipment. The 3-meter pull-out structure is useful for long machinery and project cargo, while the 250 mm pull-out widening on each side provides additional support for equipment with wide tracks or wheel spacing.

In real heavy-haul operations, trailer selection should not be based on payload alone. Buyers also need to consider cargo length, weight concentration, loading direction, tractor capacity, turning radius, slope conditions, road surface and legal axle limits. Luyi Auto’s transportation application guidance and construction and infrastructure case studies provide further reference for machinery and project-cargo transport.

Technical Specifications

For buyers comparing different payload and axle arrangements, the lowbed trailer load-capacity selection guide explains how cargo weight, route limits, tractor capability and operating cost should be evaluated together.

Strengths and Characteristics

• Three-meter longitudinal extension: The pull-out structure gives the trailer additional deck length for long excavators, bridge components, industrial assemblies and other project cargo. The extension must be fully locked through the specified locking devices before transport.
• Ten-axle load distribution: Dividing the load across ten axles can reduce concentrated pressure on individual axle groups. The actual legal payload still depends on trailer dead weight, kingpin load, axle spacing, local limits and permit conditions.
• Mixed suspension arrangement: Six air-suspended axles support the axle-lift function and more controlled axle management, while four mechanically suspended axles provide a robust structure for heavy-duty operating conditions.
• Six liftable axles: Liftable axles can help reduce unnecessary tire scrub and rolling resistance during suitable unladen or partial-load movements. They must not be used to bypass legal axle-load requirements.
• Low-profile running gear: The 245/70R17.5 tire configuration helps control deck height, which is important when moving tall equipment under bridges, utility lines or route height restrictions.
• Reinforced main beam structure: The 18 mm upper flange, 20 mm lower flange and 12 mm web are selected to resist bending and torsional stress from heavy and unevenly distributed cargo.
• Widenable loading area: Pull-out square tubes add 250 mm on each side, helping support wide crawler tracks and machinery that exceeds the standard deck width.
• Four-millimeter patterned deck: The patterned steel surface improves contact and traction during loading, although appropriate chains, blocks, lashing points and cargo-securing procedures are still required.

Buyers transporting equipment with unusual dimensions or concentrated weight should request a cargo-specific structural review rather than relying only on the nominal 100-ton rating. Luyi Auto’s custom lowbed trailer engineering service can evaluate deck dimensions, extension length, axle arrangement and loading method before production.

Advanced Safety Systems & Compliance

Heavy-haul safety depends on the complete vehicle combination, not the trailer frame alone. Before production, the trailer specification should be reviewed together with the tractor model, fifth-wheel height, pneumatic connections, electrical socket, intended cargo, operating speed, route gradient and destination-country regulations.

• Braking system: The supplied configuration uses pneumatic braking equipment and FUWA brake chambers. Final reservoir volume, valve layout, emergency braking function and tractor compatibility should be shown in the approved pneumatic diagram.
• ABS status: ABS is not included in the supplied base specification. Where ABS, EBS or specific branded braking components are legally required, they must be confirmed, priced and written into the purchase contract before production.
• Lighting and reflective markings: Factory-installed lamps, wiring and reflective stickers support vehicle visibility. Lamp position, socket type, voltage and side-marker requirements should be matched to the destination market.
• Extension locking: All extension locking points must be engaged and visually checked before the trailer enters public roads.
• Axle-lift control: Lift functions should only be used within the designed load range and local regulations. Axles should be lowered before heavy loading and whenever required for legal load distribution.
• Oversize transport review: A 3,000 mm base width, additional side widening and extended deck may require route surveys, escorts, warning signs or oversize permits in many markets.
• Cargo restraint: Chains, binders, wheel blocks, support timber and lashing arrangements should be selected according to cargo weight, shape and center of gravity.

This product should not be described as automatically compliant with every market. Final road legality depends on local gross-weight limits, axle-load rules, brake regulations, lighting standards, registration requirements and oversize-transport permits. Buyers should provide the destination country and intended operating route before confirming the order.

Our Craftsmanship & Quality Control

For an extendable 100-ton lowbed trailer, the most important manufacturing checks are concentrated around the main beam, pull-out beam, locking points, axle alignment, suspension installation and coupling area. These sections experience repeated bending, twisting and impact loads during heavy-equipment transport.

During production and pre-delivery inspection, Luyi Auto checks:

• Main beam plate dimensions, beam straightness and structural alignment
• Weld continuity and visible weld quality on load-bearing sections
• Fit and movement of the three-meter pull-out structure
• Engagement and positioning of all 12 locking-device sets
• Axle installation, wheel alignment and suspension assembly
• Axle-lift operation and air-line routing on the air-suspension group
• Pneumatic braking operation and brake-chamber installation
• Landing gear, kingpin and tractor-coupling dimensions
• Loading-ramp movement and spring assistance
• Electrical wiring, lamps and reflective markings
• Paint coverage, anti-rust treatment and accessory completeness

Inspection records should be retained with the order documents so the buyer can trace the final configuration and pre-shipment checks. When a customer requires third-party inspection, load verification or a specific acceptance procedure, the inspection method and acceptance criteria should be agreed before production starts.

More information about the production environment and manufacturing background is available on the Luyi Auto factory page.

Optional Configurations & Customization

This trailer should be finalized through an approved technical drawing. Configuration decisions should be based on the actual cargo and route rather than selecting options only by price.

• Overall dimensions: Deck length, base width, side widening and extension length can be reviewed according to the transported equipment.
• Main beam structure: Beam height, extension-beam dimensions and reinforcement layout are finalized after payload and stress review.
• Axle arrangement: Axle spacing, lifting sequence and axle-group layout should be matched to turning requirements and local axle-load regulations.
• Suspension: The supplied design combines six air-suspension axles with four mechanical-suspension axles. Any alternative layout requires a new engineering review.
• Kingpin and coupling: The 50# or 90# kingpin and approximately 1,300 mm coupling height should be matched to the buyer’s tractor.
• Braking package: ABS, EBS, brake valves, socket type and market-specific pneumatic components should be confirmed where required.
• Loading system: Mechanical spring ramps are included in the supplied configuration. Ramp length, width and support structure can be reviewed for specific machinery.
• Tires and rims: Alternative tire brands or locally available specifications can be discussed before drawing approval.
• Surface coating: Polyurethane spray paint or powder coating can be selected, with customer-specified RAL color where practical.
• Accessories: Toolbox, spare tire equipment, fire extinguisher, protection net, warning equipment and cargo-securing accessories can be confirmed in the final quotation.

For an accurate recommendation, buyers should provide cargo drawings or photos, operating weight, overall dimensions, center of gravity, track width, loading direction, tractor model, fifth-wheel height, destination country, intended routes and required quantity.

Packaging and Transportation

Because of its overall length, width and heavy-duty structure, this trailer is normally shipped by RO-RO vessel, flat rack or bulk carrier. The most economical method depends on the closed transportation dimensions, destination port, vessel availability, unloading facilities and local inland-delivery conditions.

Before shipment, exposed metal surfaces are treated with anti-rust wax and marine-grade protective paint. Removable accessories and small components are packed in cartons or wooden boxes, identified against the packing list and securely fixed to the trailer. Loading ramps, widening components, toolboxes and loose accessories are checked before port delivery.

A final pre-shipment inspection covers dimensions, extension operation, locking devices, axles, suspension, brakes, lights, paint condition and accessory quantity. Luyi Auto can provide commercial invoices, packing lists, certificates supplied with the order and other export documents required under the agreed trade terms.

Production normally requires 15–30 working days after the deposit and final drawing approval. Shipping time is separate and depends on the vessel schedule and destination. For project orders, the shipping method should be reviewed before production because deck dimensions and removable structures can materially affect freight cost.

FAQ

Can this 10-axle lowbed trailer be customized for local road regulations?

Yes, but the destination country must be confirmed before production. Trailer width, axle spacing, lighting, braking equipment, reflective markings, coupling details and oversize-transport requirements may differ by market. Final compliance items must be written into the technical agreement and quotation.

Does the base specification include ABS?

No. The supplied base configuration states that ABS is not equipped. Buyers should confirm whether ABS, EBS or a specific brake-control system is required for registration or road use in the destination market before placing the order.

Does the 100-ton rating mean I can legally carry 100 tons on public roads?

Not automatically. The nominal payload describes the design target, but legal payload depends on trailer dead weight, tractor weight, kingpin load, axle spacing, road classification, permit conditions and local gross-weight limits. A route and regulation review is required.

When should the six liftable axles be used?

The lift function is mainly intended for suitable unladen or partial-load movements where the remaining axles stay within their permitted loads. All required axles should be lowered before heavy loading and whenever demanded by local regulations or the approved operating procedure.

What information is required for an accurate quotation?

Please provide the cargo name, operating weight, overall dimensions, photos or drawings, track width, center of gravity if available, loading direction, tractor model, fifth-wheel height, destination country, route conditions, required quantity and preferred shipping term.

What is the expected production and shipping schedule?

Typical production is 15–30 working days after deposit and final drawing approval. Customized engineering, compliance changes, large quantities or third-party inspection may extend the schedule. Ocean transit time depends on the selected port, vessel type and destination.
