A heavy-duty truck is a large vehicle designed primarily for transporting goods and materials. These trucks typically have a gross vehicle weight rating (GVWR) of over 26,000 pounds, making them suitable for commercial use. They are commonly used in industries such as construction, logistics, and agriculture, where heavy loads are a regular requirement. Heavy-duty trucks come in various configurations, including tractor-trailers, dump trucks, and flatbeds. They are equipped with powerful engines and robust chassis to handle demanding tasks. Features like enhanced suspension systems and larger tires help improve stability and performance, especially when navigating rough terrains or carrying substantial loads.
