How many cubic meters of soil can a 5.6-meter rear eight-wheeler carry?
3 Answers
A 5.6-meter rear eight-wheeler can carry 20 cubic meters. Rear eight-wheeler: Also known as a rear eight-wheel dump truck or double-axle truck. It refers to a vehicle that can unload cargo by hydraulic or mechanical lifting. Also called a tipper truck. It consists of components such as the vehicle chassis, hydraulic lifting mechanism, cargo compartment, and power take-off device. Hazards of vehicle overload: Overloading causes the vehicle's tires to operate under excessive load continuously, increasing tire pressure and temperature, which can easily lead to tire blowouts. Precautions: Under normal circumstances, every occupant in the vehicle has corresponding safety belts and seats, but with overload, not everyone will have these. In the event of an accident, situations that could have been avoided may become unavoidable.
I've been driving this truck for many years. For an eight-wheeled truck with a container length of 5.6 meters, width around 2.3 meters, and height approximately 0.9 to 1 meter, the container volume ranges between 11.5 to 12.88 cubic meters. Soil density varies, with loose soil being lighter at about 1.4 tons per cubic meter, while compacted soil can be heavier, up to 1.8 tons. The truck's own weight plus the maximum load limit is generally around 25 tons. Subtracting the truck's weight of 10 tons, it can carry about 15 tons of soil. Based on these factors, the actual soil load fluctuates between 10 to 15 cubic meters. When loading, keeping the soil pile low can help approach the upper limit, but if road conditions are poor or regulations are strict, it's best not to exceed 12 cubic meters. Safety first—measure the container height before loading to avoid overloading, fines, or accidents. I usually keep it just over 12 cubic meters for stability, and this figure can serve as a reference for others working in the field.
The amount of soil this truck can haul depends on the type of soil loaded. With a 5.6-meter-long cargo box, the rear eight-wheeler I often drive has a width of 2.3 meters and a height of about 0.8 meters, giving a basic volume of just over 10 cubic meters. For looser red soil with a density of 1.3 tons per cubic meter, hauling around 12 cubic meters is manageable, while compacted soil with higher density means carrying less. The key is not to exceed the total weight limit of 25 tons, with the truck itself weighing 10 tons, leaving 15 tons for the soil. In practice, hauling 11 to 13 cubic meters is most practical—loading more can be risky. Road conditions also matter; bumpy roads can cause soil to spill, reducing the effective load. In short, it's best not to overload. Starting with 11 cubic meters is safe, efficient, and minimizes errors. This is how I estimate it on construction sites—simple and effective.
