BULK TRANSPORT FOR SOUTH AMERICA

4 Axle Rear Dump Semi Trailer South America

The CHENLU 4 axle rear dump semi trailer carries loose bulk materials such as sand, gravel and coal for construction supply and material-yard deliveries. Its high-sided cargo body contains the load during transport, while hydraulic rear tipping allows material to discharge through the rear gate.

For South American transport projects, body size and payload should match the cargo, tractor and destination-country requirements.

BODY DESIGN & UNLOADING FEATURES

What Are the Key Features of This Rear Dump Trailer?

South American This four-axle tipper combines a high-sided cargo body with hydraulic rear unloading. The axle group supports the loaded chassis, the body contains loose bulk materials, and the front-mounted cylinder raises the body for discharge.

Four-axle layout of a CHENLU end dump semi trailer

Four-Axle Chassis Layout

Four axles support the rear section of the loaded trailer and share the load carried by the axle group. Positioned beneath the cargo body, they work with the chassis and suspension to carry bulk materials during transport.

High-Sided Cargo Body

Raised sidewalls contain loose cargo such as sand, gravel and coal. External stiffeners support the body panels, while the open top provides access for loading. The rear gate closes the discharge opening during transport.

Front-Mounted Hydraulic Lift

The hydraulic cylinder sits ahead of the cargo body and raises its front end for rear tipping. As the body tilts, loose material moves towards the rear opening and discharges through the open gate.

Cargo Applications & Body Size

Which Bulk Materials Can This Tipper Carry?

This four-axle rear dump trailer is intended for loose materials such as sand, gravel and coal. Cargo weight and loading space need to be considered together: the same body can hold very different weights of different materials.

Internal Cargo Body Dimensions

The supplied drawing lists the following internal dimensions for the cargo body.

Internal Length: 9,640 mm
Internal Width: 2,300 mm
Internal Height: 1,900 mm

The lower body sides slope towards the floor. These dimensions describe the loading space; they do not state the trailer’s payload or its exact usable volume.

Sand Transport

Carry loose sand for construction supply and concrete production. Moisture changes the weight of a given volume, so a full body should not be treated as a fixed-tonnage load.

Gravel & Aggregates

Transport gravel and crushed aggregate for roadworks and building projects. Stone size and loading impact matter when selecting the cargo floor and body specification.

Coal Transport

Move loose coal between stockyards and receiving sites. Coal grade, particle size and moisture affect bulk density, so the required weight per trip should be checked against the available loading space.

For a trailer quote, send your cargo type, required payload, destination country and order quantity. Include your tractor model and loading method if available.

LOADING, CARGO-SECURING AND UNLOADING PROCESS

What Should Be Checked Before the Trailer Enters Service?

The final operating process depends on the specified bulk material, loading system, load distribution, rear-gate sequence, hydraulic package and unloading-site conditions. Follow only the released instructions for the ordered configuration.

Reference video placeholder. Confirm that it shows the ordered four-axle end dump configuration and the approved operating sequence before publication.

Define the Cargo

Provide the cargo name, loose density, moisture condition, particle size and expected loading pattern.

Confirm the Loading Method

State whether the body will be loaded by excavator, wheel loader, conveyor or another system. Include bucket size and drop height.

Distribute and Secure the Load

Keep load distribution within the approved technical release. If a cover is required, specify its material and operating method separately.

Check the Transport Cover Distinction

A temporary green sheet shown in one image does not confirm an integrated tarp or fitted cargo-cover system.

Prepare the Unloading Site

Confirm suitable ground, rear and overhead clearance, cross-slope, traffic control and the tractor's hydraulic and pneumatic connections.

Safety Note Do not infer tipping stability, maximum angle, hydraulic performance or unloading speed from a static photo. Use the released operating instructions and destination-site rules for the ordered configuration.

General Arrangement & Key Dimensions

4 Axle Rear Dump Semi Trailer Dimensions

A 10,800 mm overall layout and a 9,640 mm internal cargo body provide the basis for bulk material transport. The four-axle arrangement and hydraulic rear-tipping system are combined in one compact trailer configuration.

Overall Length 10,800 mm

Overall Width 2,500 mm

Overall Height 3,950 mm

Internal Cargo Body 9,640 × 2,300 × 1,900 mm

Built for Bulk Cargo and Rear Unloading

The body dimensions, axle arrangement and unloading system work together for the transport of sand, gravel, coal and similar loose materials.

Long High-Sided Cargo Body

The 9,640 mm internal length provides an extended loading area for loose bulk materials. The 1,900 mm internal height adds cargo space above the floor, while the sloped lower sides guide material towards the centre of the body.

Four-Axle Load Support

The four-axle group supports the rear section of the chassis and distributes the trailer load across four axle positions. Axle centres are spaced at 1,310 mm, and the specified tyre size is 13R22.5.

Hydraulic Rear Tipping

A front-mounted hydraulic cylinder raises the cargo body for rear discharge. This arrangement allows sand, gravel, coal and other loose cargo to leave through the rear gate at the unloading site.

Practical Underbody Layout

The landing gear, toolbox and side guard are arranged ahead of the axle group. The 600 × 600 mm toolbox provides onboard storage for tools and routine service items.

BUYER QUESTIONS

FAQ

Answers to common buyer questions about the four-axle end dump semi trailer, South America destination review, cargo matching and quotation requirements.

Is this a four-axle end dump semi-trailer?

The supplied images show four axle positions, a high-sided dump body, a rear gate and a front lift-cylinder area. The final end-dump mechanism, hydraulic package and operating sequence must be confirmed in the approved technical release.

Is this configuration intended for South America?

The page is prepared for a South America destination review based on the supplied application brief. Send the exact destination country and port because axle, lighting, braking, registration and permit requirements are not identical across the region.

What cargo can this trailer carry?

CHENLU can review it around a specified bulk material such as aggregate, sand, ore, coal or construction material. The cargo density, moisture, target load and loading method must be supplied before suitability, body volume and payload are calculated.

What is the payload or body volume?

No approved payload or body-volume value is published for this configuration. Both depend on the final body design, materials, tare weight, cargo density, axle limits, tractor limits and destination-country requirements.

Are the four axles and front lift cylinder confirmed?

Four axle positions and a front-mounted red cylinder are visible in the supplied images. The axle ratings, spacing, suspension, hydraulic model, pressure, stroke and control layout still require confirmation.

Does the trailer include an integrated tarp?

An integrated tarp is not confirmed. A green sheet appears tied over the body in one transport-preparation image, but that temporary covering is not proof of a fitted tarp system. Request a separate cover specification if needed.

What information is needed for a quotation?

For a South America dump semi trailer quote, send the cargo name and density, target load, loading equipment, tractor model, route, unloading-site conditions, destination country and port, required local standards, quantity, target date and preferred trade term.
