4 Axle 80-Ton High-Side Rear Dump Semi Trailer
Built for transporting coal, ore, sand, gravel, construction aggregates
and other loose bulk materials, this 4 axle dump semi trailer uses a
high-side cargo body to provide increased loading volume. A front-mounted
hydraulic lifting system raises the body for fast rear discharge through
the tailgate, making the trailer suitable for mining, quarry, construction
and bulk material transport.
Payload and body volume are configured according to the material density,
required load, axle ratings, route limits and destination regulations.
Before production: Configure for your load: Tell us the material, bulk density, required payload, loading method, tractor model, transport route and unloading site. CHENLU will use these details to recommend the body volume, axle layout and hydraulic tipping system for your quotation.

Why Choose This 4 Axle High-Side Rear Dump Trailer?
Designed for transporting coal, ore, sand, gravel, construction aggregates and other loose bulk materials, this 4 axle rear dump semi trailer combines a high-side cargo body, four-axle running gear and a hydraulic rear tipping system. It is suitable for bulk-haul work in mines, quarries, construction projects and material yards.
High-Side Body for Bulk Cargo
The reinforced high-side body provides increased loading volume for coal, ore, sand, gravel and construction aggregates. Body length, side-wall height and volume can be configured around the material density and required payload.
Four-Axle Load Distribution
The four-axle running gear distributes the loaded weight across more axle positions for heavy bulk transport. Axle ratings, suspension, tires and payload must be matched to the tractor, transport route and destination requirements.
Cargo Body Dimensions and Volume
The engineering drawing is used to confirm the high-side cargo body dimensions before production. Body length, width, side-wall height and loading volume are configured according to the material density, required payload and transport limits.

What Should Be Confirmed Before Ordering a 4 Axle Rear Dump Trailer?
A useful quotation starts with the transport job, not only a standard trailer model. CHENLU reviews the cargo, required payload, loading method, unloading site, tractor and destination before preparing the configuration.
What Material Will You Haul?
Coal, ore, sand, gravel and construction aggregates have different bulk densities and loading characteristics. These details help determine a practical cargo body size for the material.
How Much Must Each Trip Carry?
Provide the required payload and expected trip frequency. These figures guide the high-side body volume and four-axle load distribution for the proposed rear dump semi-trailer.
How Will It Be Loaded and Unloaded?
Tell us whether loading uses a wheel loader, excavator or hopper. The unloading area should provide firm, level ground, enough rear clearance and sufficient overhead space for the raised body.
Which Tractor and Route Will Be Used?
Share the tractor model, fifth-wheel height, destination country and road conditions. These details help review the coupling height, overall dimensions, axle setup and destination requirements.
PROJECT-BASED CONFIGURATION
Send the haul details, not just a trailer name.
Share your cargo, target payload, tractor model, destination country, order quantity and unloading-site conditions for a configuration proposal.

How Should the Trailer Be Loaded and Discharged?
The loading and rear-discharge cycle should be planned around the actual cargo, body configuration, hydraulic system, rear gate, tractor combination and unloading site. Final operating procedures must follow the approved build, operator instructions and local safety requirements.
Reference view of the four-axle rear-tipping configuration. Final hydraulic operation, rear-gate sequence, raised-body clearance and tipping limits must follow the approved engineering and operating documents.
Confirm the Cargo First
Verify loose bulk density, moisture, particle size and target load against the approved body, payload and cargo-specific configuration before loading begins.
Inspect Before Loading
Check the body, rear gate, locks, tyres, suspension, brakes, hydraulic connections and landing gear according to the operator's approved pre-loading procedure.
Load on a Suitable Surface
Load on a stable surface and distribute the material as specified. Avoid uncontrolled impact loading or concentrating the cargo at one point inside the high-sided body.
Secure the Transport Condition
Close and verify the rear gate, cover the load when required, and check the legal dimensions, cargo condition and axle loading before the trailer enters the road.
Prepare the Discharge Area
Use firm, level ground with sufficient overhead and rear clearance. Keep personnel and other equipment outside the tipping and discharge zone before raising the body.
Operate the Hydraulic System
Follow the approved hydraulic procedure while monitoring the body, cargo movement and site conditions. Stop immediately if the body leans, the load sticks or any abnormal condition develops.
Lower and Lock Before Travel
Fully lower the dump body, secure the rear gate and complete a post-discharge inspection before moving the trailer back into normal transport operation.

FAQ
Answers to common questions about the white 4 axle high-side rear dump semi trailer, cargo suitability, running-gear configuration, tipping conditions and quotation requirements.
What cargo can this high-sided rear dump trailer carry?
Suitability depends on the cargo's loose bulk density, particle size, moisture, abrasion and discharge behaviour. Send the material details before CHENLU recommends body dimensions, liner requirements or an approved payload basis.
Does four axles mean the trailer has a fixed payload?
No. Four visible axle positions do not establish a legal payload. Final payload depends on trailer tare weight, axle ratings, tyres, suspension, tractor loading, cargo distribution, route limits and local regulations.
Is the tractor shown in the photographs included?
No assumption should be made from the factory images. The tractor is shown as coupling and display context only. This page concerns the semi-trailer unless a separate quotation specifically includes other equipment.
Can suspension, tyres and brakes be selected for my market?
These items can be reviewed as part of the project configuration. Final brands, ratings, axle package, suspension type, tyre schedule and braking system must be confirmed in the approved quotation and component schedule for the destination market.
Can CHENLU add a tarp or body liner?
A tarp or load-cover arrangement and cargo-specific wear liner can be discussed as optional equipment. The correct solution depends on the cargo, loading impact, abrasion, moisture, weather exposure and operating conditions.
What site information is needed for safe tipping?
Provide the unloading-surface condition, slope, overhead clearance, rear clearance and any site restrictions. The operator must still follow the approved operating manual, site risk assessment and local safety procedures.
What should I send for a quotation?
Send the cargo type and loose density, moisture condition, target load, preferred body dimensions or volume, tractor details, route, destination country, unloading-site information and preferred axle, suspension, tyre and brake package. Site photos or drawings are useful where clearance is limited.
