Factory-built 14 m four-axle flatbed semi-trailer with a full-width front headboard. The production views show the open platform, four-axle group, landing gear, under-deck equipment and rear structure used on this configuration.
14 m 4 Axle 100 Ton Flatbed Semi Trailer with Headboard
This 14 m four-axle flatbed semi-trailer combines an open loading platform with a fixed full-width front headboard. 14,000 mm overall length, 2,500 mm overall width, four axle positions with 1,310 mm adjacent spacing and 11R22.5 tyres for this configuration.
Match the trailer to the load: Confirm the cargo dimensions, transport mass, support points, loading direction, restraint plan, tractor interface and destination route before production. Final payload, axle ratings, suspension, braking system, aluminum section specifications and headboard restraint rating must follow the approved quotation and production drawing.

What Makes This 14 m 4 Axle Flatbed Trailer Practical for Long Cargo?
The long open deck gives forklifts and cranes room to work around the cargo. A full-width front headboard marks the loading area, while four rear axles support weight distribution across the trailer.
A Clear Front Reference for Loading
The 1,300 mm headboard marks the front of the loading area, giving the crew an easy reference when positioning bundled steel, pipe, timber or fabricated equipment. Both sides remain open for securing and unloading.
Open Access for Forklifts and Cranes
At 14,000 mm overall length and 2,500 mm overall width, this trailer provides an open format for long cargo. Forklifts can approach from either side, while cranes can lift directly from above.
Four Axles for Heavy-Cargo Distribution
Four axles sit beneath the rear of the platform, spreading the trailer load across a longer running-gear group. Cargo can be positioned along the deck with both the axle group and tractor in mind.
CARGO FIT
Which Loads Suit This 14 m 4 Axle Flatbed Trailer?
This open-deck trailer suits long, heavy or irregular cargo that needs side or overhead loading. The examples below show where the layout is useful—and when another trailer type may be a better choice.
Steel, pipe and timber bundles
The long open deck leaves room for cargo that does not fit inside a box body. Cranes can lift from above, and forklifts can work from either side.
Fabricated equipment and large components
Open sides make it easier to position irregular components, reach their support points and secure the load without working around fixed body panels.
Pallets and construction materials
Side access suits yards and construction sites where goods are handled by forklift and may need to be unloaded from different positions along the deck.
THIS LAYOUT MAKES SENSE WHEN
- The cargo needs crane or side-forklift access.
- The 14 m overall length fits the route and loading site.
- The load can be supported and secured on an open deck.
CONSIDER ANOTHER TRAILER WHEN
- Tracked machinery needs a lower deck and loading ramps.
- The cargo needs weather protection or enclosed sides.
- The work is limited to containers and requires a dedicated chassis.
Will your cargo fit this flatbed?
Send the cargo dimensions, transport weight, loading method and destination country. CHENLU can then compare the load with this 14 m four-axle layout.

Axles and Local Parts Support
Choose an axle brand and rating that suit the required load and can be serviced in the destination market.
Suspension for the Route
Select the suspension type for the road surface, trip distance and local maintenance conditions.
Brakes and Tractor Connections
Confirm the brake system, ABS or EBS requirement, voltage and air and electrical connections used by the tractor.
Deck Surface and Cargo Supports
Choose the deck finish and identify any concentrated support areas, cradles or other cargo-specific fittings.
Kingpin and Coupling Height
Provide the tractor model or fifth-wheel height so the trailer can sit level and maintain turning clearance.
Tie-Downs and Load Securing
List the required lashing points, stakes, twist locks or support frames based on the cargo and loading method.
Equipment for the Destination
Confirm the lighting, reflective markings, side guards, mudguards, tyres and spare-wheel arrangement required for the market.

4 Axle Flatbed Semi Trailer Video
This video presents a completed four-axle flatbed semi-trailer from multiple exterior angles. Buyers can review the open platform, front headboard, four-axle running gear and visible underdeck equipment before discussing a project-specific configuration.
Completed-trailer display showing the overall exterior and visible configuration. This is a product walkaround, not a loading test, payload demonstration or operating guide. Final equipment must follow the approved order specification.
Overall Trailer Profile
The walkaround shows the proportions of the platform, the front headboard and the rear structure. Use this view to compare the displayed configuration with the intended cargo and operating route.
Open Flatbed Platform
The open deck provides side access for different loading methods. Final usable length, width, support areas and cargo-restraint locations must be defined in the approved drawing.
Four-Axle Running Gear
Four axle positions are visible beneath the rear section of the platform. Axle make, individual rating, suspension specification, tyre selection and allowable load distribution remain project-specific.
Underdeck Equipment Layout
The video provides a closer view of the landing gear, side protection and visible storage or service areas. The final position and specification of each component should be listed in the technical proposal.
Configuration Details to Review
Use the completed-trailer video to identify required changes to the headboard, deck equipment, restraint points, storage, lighting and other visible components before the production configuration is approved.

FAQ
Answers to common questions about the 4 axle flatbed trailer with front wall, cargo suitability, restraint planning and quotation requirements.
What is the purpose of the front wall on this flatbed trailer?
The fixed front wall provides a defined front boundary for cargo positioning and securing review. Its structural role, dimensions and permitted load interaction must follow the approved design. It does not automatically replace chains, straps, blocks, chocks or other required cargo restraints.
Is this the same as a standard four-axle flatbed semi-trailer?
This page is specifically for a four-axle open platform with a fixed full-width front wall or headboard. A general four-axle flatbed trailer may use a similar open deck without making the front-wall configuration the main design feature.
Can this flatbed trailer transport containers?
Only when the final deck dimensions and container-lock arrangement are designed and approved for the required container size. The supplied images do not establish a confirmed twist-lock pattern, so container compatibility should not be assumed.
What cargo can be carried on the open deck?
Potential cargo classes include bundled steel, pipe, timber, building materials, machinery, fabricated equipment and general freight. Suitability depends on cargo dimensions, weight distribution, support points, loading method, restraints and applicable road rules.
Does the four-axle layout confirm a particular payload?
No. Four visible axle positions do not establish one universal legal payload. Final payload and GVW must be calculated from the approved axle ratings, trailer tare weight, cargo distribution, tractor combination, route and local regulations.
Can the front wall size be customized?
Front-wall height, width and structural configuration may be reviewed during engineering. The final design should follow the cargo geometry, working clearance, structural requirements, tractor interface and destination restrictions.
What information should I send for a quotation?
Send the cargo type, dimensions, maximum weight, cargo drawing or photos, loading method, tractor model or fifth-wheel height, destination country, required deck dimensions and any container or cargo-restraint requirements.
