4 Axle Rear Dump Trailer – High Volume Hauler
- Heaped capacity: 28 m³ / 32 m³ / 36 m³ – matched for aggregates, coal, overburden, and mill feed
- Twin‑cylinder lift system – two 180 mm bore hoists share oil flow; if one fails, the other lowers load safely without tipping
- AR450 wear liner floor – 12 mm abrasion‑resistant steel; outlasts standard Hardox 400 by 30% on sharp rock
- Three‑stage tailgate – bottom section opens first for fines, middle for cobbles, fully open for boulders; controlled from cab
- Variable dumping angle – 48° standard / 52° with flip‑up extension; sticky clay releases fully without manual knocking
- Load‑sensing axle scale – real‑time weight per axle; automatic airbag inflation keeps each axle within legal limit
- Quick return assist – nitrogen‑charged accumulators raise empty bed in 9 seconds vs 14 seconds conventional

Product Advantages
Efficient Rear Unloading Design
The rear-dump mechanism allows for rapid and controlled unloading of materials directly at the site, significantly reducing turnaround time compared to side-unloading or manual methods. This streamlines operations in fast-paced environments like construction and mining.
High Volume Capacity
These trailers are engineered with a large, open-box design to maximize cargo volume, typically ranging from 32 to 45 CBM or more. This high capacity makes them exceptionally cost-effective for transporting bulk commodities such as sand, gravel, and demolition debris.
Robust Construction & Durability
Built to withstand extreme conditions, they feature heavy-duty steel frames, reinforced sides, and reliable hydraulic systems. This ensures longevity and minimal downtime when operating on rough terrain or hauling heavy loads like rocks and aggregate.
Superior Traction & Stability
When loaded, the cargo weight is centered over the trailer's axles and the tractor's drive wheels, providing excellent traction and stability during transport. This enhances safety and performance, especially on uneven or inclined job site roads.
Operational Versatility
They are highly adaptable to various industries and materials. With customizable options in axle configuration (e.g., 2 to 4 axles), chassis strength, and body size, they can be tailored for specific tasks in quarrying, earthmoving, agriculture, and heavy construction projects.
