Whether you are in the transportation industry or just curious about these massive vehicles on the road, understanding what a semi-trailer is and how it operates can be beneficial. This comprehensive guide to semi-trailers will cover the basics, including the different types, their components, and their functions.

 

Types of Semi-Trailers

 

1. Low flat semi-trailers

These types of semi-trailers are designed for transporting loads that are low to the ground. Low flat semi-trailers are commonly used to transport heavy machinery, construction equipment, and other large objects. They have a very low ground clearance and are often equipped with hydraulic lifts to help raise and lower the trailer as needed.

 

2. Enclosed semi-trailers

As the name suggests, enclosed semi-trailers have an enclosed body that provides protection to the cargo during transportation. These trailers are commonly used for transporting fragile items, perishable goods, and valuable merchandise. They are equipped with climate control systems that help maintain a consistent temperature throughout the journey.

 

3. Flatbed semi-trailers

Flatbed semi-trailers are the most commonly used types of semi-trailers. They consist of a flat platform that is mounted on a trailer chassis. These trailers are commonly used for transporting goods that can be loaded and unloaded from the top or sides. Flatbed semi-trailers are commonly used for transporting building materials, vehicles, and heavy machinery.

Components of a Semi-Trailer

 

1. Axles

Semi-trailers have two or more axles that help distribute the weight of the cargo. Axles are equipped with brakes that are activated by the driver through the brake pedal.

 

2. Suspension

Semi-trailers have a suspension system that absorbs shocks and vibrations during transportation. The suspension system consists of leaf springs, airbags, or a combination of both.

 

3. Landing Gear

The landing gear is located at the front of the trailer and is used to support the weight of the trailer when it is not connected to a truck. It consists of two metal legs that are lowered to the ground and raised when the trailer is connected to a truck.

 

Functions of a Semi-Trailer

 

1. Transportation

The primary function of a semi-trailer is to transport goods from one location to another. Semi-trailers are capable of carrying large quantities of cargo efficiently and cost-effectively.

 

2. Storage

Semi-trailers are also used as temporary storage units for goods during transportation. They provide a secure location to store goods before they are unloaded at their final destination.

 

3. Advertising

Semi-trailers are often used as mobile billboards to advertise products or services. Companies can wrap their trailers with graphics and branding that can be seen by thousands of people on the road.

In conclusion, semi-trailers come in various shapes and sizes to meet different transportation needs. Every type of semi-trailer has a unique design and is used to transport specific types of cargo.
