Which type of trailer has a ramp in the rear to assist with loading and unloading cargo?

Types of Trailers

A trailer is a non-motorized vehicle towed by a powered vehicle. There are several types of trailers designed for various purposes, each with its own unique features and functions.

1) Flatbed trailer

A flatbed trailer is a type of trailer with an open flatbed platform without sides or roof. It is commonly used for transporting oversized or irregularly shaped cargo that cannot fit inside a standard enclosed trailer.

2) Refrigerated trailer

A refrigerated trailer, also known as a reefer trailer, is designed to transport perishable goods at controlled temperatures. It is equipped with a refrigeration unit to maintain a specific temperature range during transit.

3) Enclosed trailer

An enclosed trailer is a fully enclosed trailer with walls and a roof, providing protection for the cargo from exposure to weather elements. It is commonly used for transporting sensitive or valuable cargo that requires secure and weatherproof transportation.

4) Utility trailer

A utility trailer typically has a ramp in the rear to assist with loading and unloading cargo. It is designed for versatility and convenience, making it easy to transport a range of items, including heavy or wheeled cargo.

Final answer:

A utility trailer typically has a ramp for loading cargo, and a trailer bouncing slowly likely indicates it is nearly empty, because an empty trailer has more suspension travel and bounces more.

Explanation:

The type of trailer that has a ramp in the rear to assist with loading and unloading cargo is typically a utility trailer. Utility trailers are designed for versatility and convenience in transporting a range of items, providing easy access through a ramp for heavy or wheeled cargo. As for the observation of a trailer bouncing up and down slowly on the highway, this behavior suggests that the trailer is likely nearly empty. A heavily loaded trailer would have less suspension travel due to the weight pushing down on it, making it less prone to bounce. In contrast, an empty or lightly loaded trailer has more suspension travel, and thus, it is likely to oscillate more when impacted by bumps or irregularities in the road surface.
