Which of the following is a common type of heavy trailer?

A flatbed trailer is indeed a common type of heavy trailer, and its design offers significant versatility for transporting various loads. Flatbed trailers have a flat, level platform without sides or a roof, making them ideal for hauling oversized or heavy machinery, construction materials, and other large items that may not fit into enclosed trailers.

This open design allows for easy loading and unloading from any side, which is particularly useful when using forklifts or cranes. Additionally, flatbed trailers can accommodate a wide range of cargo with various tie-down points to secure the load, ensuring it stays in place during transit.

While other trailer types like refrigerator trailers, utility trailers, and car haulers serve specific purposes, the flatbed trailer is distinguished by its versatility and capacity to handle many loads, making it a staple in heavy transport logistics. Thus, the flatbed trailer is a prime example of a common heavy trailer.
