Semi-trailers play a vital role in modern logistics and freight transportation. Different types of semi-trailers have their own uses and characteristics to adapt to diverse and complex transportation needs. Each type of semi-trailer will be introduced in detail below.
Flatbed Trailer
Features: Flatbed semi-trailer is a semi-trailer without walls and roof. It has the characteristics of simple structure and strong adaptability.
Application scenario: Mainly used for transporting various goods with unlimited length, width and height, such as construction materials, steel products and heavy machinery.
Technological development: In recent years, with the application of lightweight and strengthened materials, the load-carrying capacity of flatbed semi-trailers has been greatly improved.
Container trailer (Container Trailer) also known as skeleton vehicle
Features: Specifically designed for shipping containers, they generally have a locking device to secure the container.
Application scenarios: Widely used in international cargo transportation, port loading and unloading and long-distance logistics.
Technological developments: Modern container semi-trailers are often equipped with advanced GPS tracking and automatic braking systems.
Refrigerated Trailer
Features: There is a refrigeration device inside, which can maintain a stable low-temperature environment.
Application scenario: Used to transport frozen or refrigerated food, pharmaceutical products and other goods that require temperature control.
Technological Development: With advances in energy efficiency and refrigeration technology, modern refrigerated semi-trailers are more energy-efficient and environmentally friendly.
Tanker Trailer
Features: It has a well-sealed tank for loading liquid or gas or powder
Application scenarios: Mainly used for transporting petroleum, chemicals, liquefied gas, etc.
Technological development: Anti-corrosion, anti-leakage and multi-layer isolation technologies are often used to ensure the safety of goods.
Lowboy Trailer
Features: The body is low, suitable for loading high-height or heavy goods.
Application scenario: Commonly used to transport large equipment such as excavators, cranes, etc.
Technological development: New low-bed semi-trailers use high-strength steel and advanced suspension systems to improve safety and stability.
Dump Trailer
Features: The carriage can be tilted automatically or manually for unloading.
Application scenario: Mainly used for transporting earth, rock, ore and other bulk materials.
Technological development: Automatic unloading system and anti-skid design make operation more convenient and safe
Specialized semi-trailer
Features: Designed for specific goods or specific conditions, such as over-wide, over-height, over-weight or goods with special needs.
Application scenario: Mainly used to transport wind turbine blades, ship hulls, aircraft parts and other goods with special sizes or requirements.
Technology development: Modular and customizable designs are often used to adapt to various special needs.
Curtain-sider semi-trailer
Features: Featuring a sliding roof and side walls, it can quickly load and unload cargo while protecting it from the environment.
Application scenario: Suitable for situations where quick loading and unloading is required but goods need to be protected, such as electronic products, furniture, etc.
Technology Development: Modern fleet semi-trailers often feature high-strength materials and advanced automatic control systems.
Extendable Trailer
Features: The body can be extended to accommodate cargo of varying lengths.
Application scenario: transporting long goods such as long products, steel bars, and pipes.
Technological development: Advanced hydraulic system and structural design make the extension more stable while maintaining high load-bearing performance.
Summarize
There are many types of semi-trailers, each with its own characteristics and application scenarios. With the continuous development of the logistics and transportation industry, semi-trailers are gradually undergoing technological innovation and optimization to adapt to more complex and diversified transportation needs. From flatbed semi-trailers to special semi-trailers, from refrigerated transportation to heavy-duty cargo transportation, semi-trailers cover almost all the needs of modern logistics and freight and are an indispensable part of modern society.
