The capacities of trucks for different types of materials vary based on the truck type and the material's characteristics.
1. **Dump Trucks**: Typically used for loose materials like sand, gravel, or demolition waste. Their capacity is measured in cubic yards, ranging from 10 to 16 cubic yards for standard models. Heavier materials like gravel may reduce the volume capacity due to weight limits.
2. **Flatbed Trucks**: Ideal for large, heavy, or irregularly shaped items such as machinery or construction materials. Capacity is measured in weight (tons) rather than volume, with typical limits between 15 to 25 tons, depending on the truck size and axle configuration.
3. **Box Trucks**: Used for transporting goods that need protection from the elements, such as furniture or packaged goods. Capacity is measured in cubic feet, with common sizes ranging from 1,000 to 3,000 cubic feet. Weight limits also apply, typically around 7 to 10 tons.
4. **Tanker Trucks**: Designed for liquids or gases, with capacity measured in gallons or liters. Small tankers hold around 3,000 gallons, while larger ones can carry up to 11,600 gallons. The density of the liquid affects the weight capacity.
5. **Refrigerated Trucks**: Used for perishable goods, with capacity measured in cubic feet. Sizes range from 1,000 to 2,500 cubic feet, with weight limits similar to box trucks. Temperature control is a key feature.
6. **Logging Trucks**: Specifically for transporting logs, with capacity measured in weight (tons) and length. They can carry up to 40 tons, depending on the truck and log size.
Each truck type is optimized for specific materials, balancing volume and weight capacities to comply with legal and safety standards.
