CHENLU 4 axle rear dump semi trailer with air suspension, a high-sided cargo body and front-mounted hydraulic lifting system.
100 Ton 4 Axle Rear Dump Semi Trailer with Air Suspension
The CHENLU 4 axle rear dump semi trailer carries sand, gravel, coal and other loose bulk materials for construction, quarry and stockyard transport. Its high-sided cargo body tips to the rear for unloading, while the air suspension supports load equalization across the four-axle group and absorbs road shock during transport. This configuration is intended for buyers who prefer air-suspension running gear on a four-axle tipper. Body size and payload are matched to the cargo density, tractor setup, transport route and destination-country requirements.
Before production: Send your cargo type, required payload, destination country and tractor model. We will match the cargo body, four-axle running gear, air suspension and hydraulic system to the transport task.
Why choose CHENLU 4-axle rear-discharge semi-trailer?
This configuration combines four-axle running gear, air suspension and a high-sided rear-tipping body. Each system has a clear role: the axle group supports the loaded chassis, the air suspension manages changing axle loads, and the hydraulic tipping system unloads loose cargo through the rear gate.
Four-Axle Load Distribution
The four-axle group provides additional support points beneath the long cargo body. With 1,310 mm between adjacent axle centres, the layout spreads the trailer load across four axle positions and provides a practical basis for matching the chassis to the required payload and transport route.
Air Suspension for Changing Loads
Air springs respond to changes between loaded and empty operation and help equalize load across the axle group. They also reduce the transfer of road shock from the running gear to the chassis. Ride height, air controls and axle ratings are matched to the tractor and operating route.
High-Sided Body with Rear Discharge
The high-sided cargo body provides loading space for sand, gravel, coal and similar loose materials. A front-mounted hydraulic cylinder raises the body, allowing the cargo to move towards the rear gate and discharge at the delivery site. Body dimensions and plate specifications are selected according to cargo density, particle size and loading method.
What Information Is Needed to Configure a 4-Axle Dump Trailer?
The right body and running gear begin with the material—not a generic tonnage figure. Cargo density sets the volume requirement, while the tractor, loading method and unloading site determine how the trailer should be arranged.
Send the Details That Change the Trailer Configuration
Provide the cargo profile, intended load, tractor model, loading equipment and unloading conditions. CHENLU can then prepare a four-axle rear dump semi trailer proposal around the body, air-suspension running gear and hydraulic tipping requirements.
| Start With | How It Shapes the Trailer | Information to Send |
|---|---|---|
| Cargo profile Sand, gravel, coal, aggregate or another loose bulk material | Bulk density determines how much body volume is needed for the intended cargo weight. Moisture, particle size and abrasion also influence the floor, sidewalls, wear protection and rear-gate arrangement. |
|
| Target load and work cycle Intended cargo weight and expected operating frequency | The intended load affects body proportions, axle and suspension ratings, tyre selection and hydraulic duty. Final payload must also remain within the limits of the complete tractor-trailer combination and transport route. |
|
| Loading method Wheel loader, excavator, hopper or conveyor | Bucket size and drop height determine the required loading clearance and likely impact areas. These conditions guide the body opening, floor protection and local sidewall reinforcement. |
|
| Tractor and air suspension Coupling, ride height and service connections | Fifth-wheel height and coupling geometry must suit the tractor. Air-suspension capacity and ride height must also be matched across the four-axle running gear for the intended operating condition. |
|
| Route and unloading site Road limits, ground conditions and tipping clearance | Route restrictions affect overall dimensions and axle loading. Ground slope, overhead clearance and the space behind the trailer affect the tipping envelope and rear-discharge arrangement. |

4 Axle Rear Dump Semi Trailer: Finished Product Walkaround
Watch a completed CHENLU 4 axle rear dump semi trailer from multiple exterior angles. The video provides a closer look at the high-sided cargo body, four-axle air suspension, front hydraulic lifting system, landing gear and rear-gate arrangement.
Finished-product walkaround of the four-axle rear dump semi trailer with air suspension featured on this page.
Key Details to Review in the Video
These exterior details provide a practical starting point for comparing the body, running gear and tipping arrangement with your cargo and transport requirements.
High-Sided Cargo Body
The rectangular steel body provides loading space for sand, gravel, coal, aggregate and other loose bulk materials. External sidewall reinforcement supports the long body structure.
Four-Axle Air Suspension
The four-axle running gear supports the rear section of the cargo body. Air suspension helps manage changing axle loads and absorbs road shock during loaded and empty travel.
Front Hydraulic Lifting System
A front-mounted hydraulic cylinder raises the cargo body for rear discharge. Its forward position keeps the main lifting equipment accessible around the front of the trailer.
Rear Gate and Chassis Equipment
The finished trailer includes a hinged rear gate, landing gear, lighting, side protection and spare-wheel carriers. These details can be matched to the operating route and destination market.
