A tri axle dump truck typically carries 15 to 17 cubic yards of material.
A tri axle dump truck can transport between 15 to 17 cubic yards of material, depending on the truck's size, bed dimensions, and the material's density. This capacity makes it suitable for medium to large construction projects, landscaping jobs, and material hauling. The exact volume may vary slightly based on the truck's configuration and the weight limits imposed by local regulations.
Factors affecting cubic yard capacity
- Truck bed dimensions: Longer and wider beds hold more material
- Material density: Heavier materials like gravel may reach weight limits before filling the bed
- Local weight restrictions: Federal and state laws limit total truck weight
- Bed shape: Sloped or tapered beds may reduce usable volume
Comparison of dump truck types and capacities
| Truck Type | Cubic Yards | Typical Use |
|---|---|---|
| Standard pickup | 1-2 | Small projects, landscaping |
| Single axle | 6-8 | Light construction, residential |
| Tri axle | 15-17 | Commercial construction, large projects |
| Quad axle | 18-22 | Heavy-duty hauling, large-scale projects |
Calculating material needs for your project
To determine how many truckloads you need, divide your project's total cubic yardage by 15-17 (the tri axle capacity). For example, a 50-cubic-yard project would require approximately 3 truckloads. Always add 10% to your calculations to account for compaction and settling of materials like soil or gravel.
