A trailer (also called a semi trailer) is a non-powered vehicle designed to be towed by a tractor truck, forming a complete road transport combination. It is a core piece of equipment for modern logistics, engineering transportation, and bulk cargo delivery, greatly improving transport efficiency, load capacity, and operational flexibility.
We offer a complete range of semi trailers designed for diverse transportation needs, from general cargo and containers to bulk materials, liquids, heavy machinery, and specialized vehicles. Each type is engineered with high-strength materials, reliable performance, and customizable configurations to suit global market standards. Below are our main trailer categories:
Lowbed Trailer
Lowbed trailers feature a low-profile deck structure, ideal for transporting oversized and heavy equipment such as excavators, loaders, cranes, bulldozers, and other engineering machinery. They offer easy loading, strong stability, and high load capacity for heavy-duty transportation.
Flatbed Trailer
Flatbed trailers provide a flat, open platform for convenient loading and unloading of general cargo, steel, building materials, containers, and packaged goods. With a simple and durable structure, they are widely used in road logistics and cross-border transportation.
Fuel Tanker Trailer
Fuel tanker trailers are specially designed for the safe transportation of diesel, gasoline, crude oil, and other petroleum products. Equipped with anti-explosion and anti-leakage systems, multiple compartments, and reliable valves, they ensure high safety and efficiency for liquid fuel delivery.
Cement Bulker
Cement bulker trailers are used for the pneumatic transportation of bulk cement, fly ash, lime powder, and other dry bulk materials. Their V-shaped or W-shaped tank design and reliable air compressor system ensure fast unloading and low residue.
Cargo Trailer
Cargo trailers are versatile for general goods transportation and are suitable for logistics, agriculture, and daily distribution. They provide reliable protection for various packaged and loose cargo with a stable structure and good adaptability.
Container Chassis
Container chassis are dedicated to transporting 20ft, 40ft, 45ft, and other standard containers. Widely used in ports, terminals, and container logistics, they feature locking devices to ensure safe and stable container delivery.
Dump Trailer
Dump trailers are equipped with a hydraulic lifting system for the automatic unloading of sand, gravel, coal, ore, construction waste, and other bulk materials. They are widely used on construction sites, in mines, and in infrastructure projects.
Car Carrier Trailer
Car carrier trailers are designed for transporting passenger vehicles, SUVs, and small commercial vehicles. With a multi-layer structure and fixed protection devices, they improve transport efficiency and ensure vehicle safety during transit.
ISO Tank
ISO tanks are used for transporting liquid chemicals, edible liquids, hazardous liquids, and other special materials under international container standards. They feature high sealing performance, corrosion resistance, and compliance with global transportation regulations.
Full Trailer
Full trailers have independent front and rear axles and are towed by a truck without a fifth wheel. They are flexible for short-distance transportation and can be used in factories, ports, and logistics parks.
Skeleton Semi Trailer
Skeleton semi trailers adopt a lightweight frame structure and are mainly used for container transportation. They reduce self-weight, increase effective load, and are highly cost-effective for port and logistics companies.
Side Wall Trailer
Side wall trailers come with detachable or fixed side panels and are suitable for bulk cargo, agricultural products, construction materials, and general goods. They prevent cargo from falling and improve loading safety.
LPG Tank Semi Trailer
LPG tank semi trailers are professional equipment for transporting liquefied petroleum gas. They use high-quality pressure vessels, safety valves, and anti-leakage systems to meet strict standards for gas transportation.
Heavy-Duty Steel Structure
Our semi trailers use high-strength Q345 steel with a reinforced frame design, ensuring high rigidity, stable load capacity, and a long service life.
High Load Capacity
We offer load capacity options ranging from 20 to 100 tons with an optimized structure, suitable for the transportation of heavy cargo, machinery, containers, and bulk goods.
Reliable Suspension & Axle System
Equipped with famous-brand suspension systems and axles (FUWA, BPW), our trailers provide stable performance, strong shock absorption, and safety on various road conditions.
Excellent Anti-Corrosion Treatment
By adopting a sandblasting and multi-layer painting process, our trailers achieve strong rust resistance and durability in harsh working environments.
Flexible Customization
We support full customization of size, axles, suspension, color, logo, and configuration to meet different market demands.
International Quality Certification
Our semi trailers comply with ISO 9001, CE, DOT, and other international standards, with strict quality testing to ensure safety and reliability.
Our semi trailers are widely used in global logistics, construction, mining, and chemical transportation, meeting the transportation needs of various heavy and bulk cargo.
