Hree-axle dump trucks enhance their overall load-carrying capacity by adding a third axle, making them suitable for transporting medium to heavy goods such as sand, gravel, and building materials. Their typical configuration is a 6x2 drive form (with the second axle being a tag axle), which effectively balances the load-carrying requirements and steering flexibility.

The rear-tipping dump semi-trailer is a heavy-duty transport vehicle with a hydraulic lifting system that raises the front of the body to unload cargo through the rear. Built on a multi-axle chassis with a high-strength steel body, it typically offers a capacity of 30–60 cubic meters, making it ideal for hauling sand, gravel, coal, and construction debris in mining, quarrying, and bulk material logistics.

The side-tipping dump semi-trailer is a heavy-duty transport vehicle with hydraulic cylinders that tip the body to the left or right for rapid unloading. Built on a multi-axle chassis with a high-strength steel body, it typically offers 30–60 m³ capacity, making it ideal for hauling sand, gravel, coal, and construction debris in mining, quarrying, and bulk logistics.
