A tri-axle dump truck can hold 10 to 16 cubic yards of material, which equals 14 to 22 tons depending on the material density.
A tri-axle dump truck is a common heavy-duty vehicle used in construction and material hauling. Its capacity depends on the material being transported, as different materials have different densities. On average, a tri-axle dump truck can carry between 14 to 22 tons of material, with the exact weight varying based on the specific material and truck configuration.
Material Capacity by Type
- Gravel: 14-18 tons (10-12 cubic yards)
- Sand: 15-20 tons (10-13 cubic yards)
- Topsoil: 12-16 tons (10-14 cubic yards)
- Crushed stone: 16-22 tons (12-16 cubic yards)
Tri-Axle vs Other Dump Truck Capacities
| Truck Type | Cubic Yards | Tons (approx.) |
|---|---|---|
| Standard Dump Truck | 10-14 | 12-18 |
| Tri-Axle Dump Truck | 10-16 | 14-22 |
| Tandem Axle | 8-12 | 10-16 |
| Quad Axle | 16-20 | 20-28 |
Factors Affecting Load Capacity
Several factors influence how much a tri-axle dump truck can carry:
- Material density and moisture content
- Truck bed dimensions and configuration
- State and local weight regulations
- Road conditions and terrain
- Legal axle weight limits
Legal Weight Considerations
Most states limit tri-axle dump trucks to 48,000-54,000 pounds (24-27 tons) gross vehicle weight. The actual payload capacity is typically 20-24 tons when accounting for the truck's own weight. Always check local regulations as they vary by jurisdiction.
