12.5m 2 Axle 40ft Skeleton Semi Trailer
CHENLU 2 axle skeleton semi trailer uses a 12.5 m open-frame chassis for container transport. CHENLU show container twist locks, a tandem axle group, landing gear, side protection, rear protection and the installed underframe equipment. The supplied drawing provides a 12,500 mm overall-length reference, 2,500 mm overall width and 1,310 mm axle spacing. The container size, twist-lock pattern and load distribution must be matched to the approved order before production.
Before production: Confirm the container size and loaded mass, twist-lock positions, axle-load distribution, fifth-wheel height, kingpin interface, brake and electrical connections, tire specification, tractor details and destination requirements.

Why Review This 2 Axle 40ft Skeleton Semi Trailer?
CHENLU supplied establishes the starting geometry for this
two-axle container chassis: a 12,500 mm overall length, 2,500 mm
overall width and 1,310 mm tandem-axle spacing.
The final configuration must still be matched to the container
footprint, loaded mass, tractor interface, axle-load distribution
and destination route.
Container Lock Layout for the Required Footprint
The open-frame chassis uses deck-mounted twist locks to connect with the container corner castings. Confirm the required 40ft container position and any additional 20ft loading arrangement against the approved lock drawing before quotation.
Tandem-Axle Geometry for Load Planning
The dual-axle layout provides this semi-trailer with a more stable load capacity, ensuring vehicle stability.
Open Chassis for Inspection and Service Access
The exposed frame provides a clear view of the main rails, cross-members, twist locks, landing gear and running-gear installation. Final steel specifications, suspension, brakes, electrical routing and component ratings must be listed in the approved order documents.
What Must Be Confirmed for a 2 Axle 40ft Container Chassis?
Match the chassis to the container and tractor
Send the information below before the twist-lock layout and two-axle running gear are released for production.
| Buyer Information | Configuration Decision |
|---|---|
| Container size and arrangement | State whether the job requires one 40ft container, two 20ft containers or another approved footprint. This sets the twist-lock stations, frame support points and rear clearance. |
| Loaded container mass | Provide the container tare, cargo mass and expected centre of gravity. These values are used to review kingpin load, axle loads and the required chassis structure. |
| Corner castings and twist locks | The lower corner-casting positions must align with the proposed lock layout. Confirm the lock count, locations and operating type in the approved drawing. |
| Tractor and fifth-wheel details | Send the tractor model, fifth-wheel height and coupling details so the kingpin interface, chassis attitude, turning clearance, air lines and electrical connection can be checked. |
| Route and container-handling method | Identify the destination country, operating route and whether the container is handled by crane, reach stacker or other terminal equipment. Route limits and working clearances must be reviewed before production. |

12.5m 2 Axle 40ft Skeleton Semi Trailer Specifications
Drawing-backed dimensions are listed separately from the items that depend on the container load, tractor and destination. This keeps the specification useful without turning a factory photo into a payload claim.

| Suspension, tires and brakes | Order selection Matched to axle loads, route and destination The quotation should state suspension type and rating, tire size and load index, brake equipment and installed component models. |
| Tractor interface | Buyer input Kingpin, fifth-wheel height and service connections Send the tractor model or interface dimensions so coupling height, turning clearance, air lines and electrical connections can be checked. |
What Should Be Checked Before a Container Is Placed on the Chassis?
Container placement must follow the approved support and locking plan, tractor interface, route review and released operating procedure. A visually similar open frame does not prove universal container compatibility.
Replace this placeholder with an approved video that matches the ordered chassis, container-lock plan and released operating procedure.
Identify the Container
Provide the container type, nominal length, tare weight, cargo weight, corner-casting arrangement and any special handling condition.
Confirm the Support and Locking Plan
Match the corner castings to the approved support and locking points. Confirm lock type, count, spacing, rating and operating position.
Check the Tractor and Route
Confirm the tractor, fifth-wheel height, kingpin, air and electrical connections, turning envelope, axle limits and destination rules.
Load and Secure as Released
Use approved handling equipment, position the chassis on suitable ground and inspect every approved locking point before dispatch.
Recheck After Movement
After the first controlled movement, inspect locking indicators, container position, clearances, lights and load distribution.

FAQ
Answers to common buyer questions about the two-axle skeleton semi trailer, container fit, tractor matching and quotation requirements.
Is this a two-axle skeleton semi trailer?
The supplied images show an open skeletal frame and two visible axle positions in a tandem group. The final model, axle ratings and component package must be confirmed in the approved drawing and quotation.
Can it carry a shipping container?
The open frame is presented for a container-carrying fit review, but the supplied images do not confirm the lock system or container compatibility. Send the container type, length, tare and corner-casting layout for engineering confirmation.
Is it a 20 ft or 40 ft container chassis?
That is not confirmed by the image set. The final container length, support points and locking arrangement must be stated in the controlled drawing and approved quotation.
What is the payload?
No payload, tare or gross vehicle weight is published for this representative configuration. These values depend on the final frame, running gear, container weight, route limits and destination requirements.
What suspension and tires are installed?
The photographs do not confirm the suspension type, axle rating, tire size, brand or load index. Request the component schedule for the specific build.
What tractor information is needed?
Provide the tractor model, fifth-wheel height, kingpin interface, air and electrical connections, route restrictions and any local equipment requirements. These details affect fit and release review.
What information is needed for a quotation?
Send the container type and dimensions, tare and cargo weight, intended route, destination country and port, tractor model, required locking arrangement, quantity, target date and preferred trade term.
