3-axle a van semi-trailer is a type of trailer that is attached to the back of a truck. It has three axles that support six wheels and is designed for long-distance road transport. The three axles can be placed in different arrangements, such as 3x 2 or 3x 3. This type of trailer is used for various purposes, such as transporting cars, containers, and other goods.
There are different types of 3-axle a van semi-trailers, such as:
Reefer trailers
A reefer trailer is a type of semi-trailer that is designed to transport goods at controlled temperatures. This type of trailer is commonly used for food products such as meat, dairy, and vegetables. Reefer trailers have refrigeration units that can cool or freeze products to maintain their quality. These trailers also have insulation that prevents temperature fluctuations during transportation.
Car carrier trailers
Car carrier trailers are designed to transport vehicles such as trucks, SUVs, and vans. These trailers have ramps, special axle arrangements, and adjustable wheel straps that make loading and unloading vehicles easy. Car carrier trailers also have a secure system such as wheel nets and soft straps that secure the vehicles during transportation.
Container chassis trailers
Container chassis trailers are designed to transport shipping containers. These trailers have a flat and strong deck with multiple container mounting points. In addition, container chassis trailers are equipped with twist locks and container lashing points that secure the container during transportation.
Lowboy trailers
They are designed to transport heavy and oversized equipment such as construction, agricultural, and mining equipment. Lowboy trailers have a low deck height that allows for easy loading and unloading of equipment. They also have removable goosenecks and multiple axle configurations that provide better stability and weight distribution during transportation.
Here are the specifications of the 3-axle van semi-trailer:
Load capacity
Van semi-trailers have a maximum load capacity of up to 30 tons, which is equivalent to 66,140 pounds. The load capacity of the trailers is distributed evenly so that the axles and wheels do not suffer from damage when transporting cargo.
Overall weight
Vans have a gross weight of about 40 tons (88,185 pounds) or more, depending on the design and other specifications of the van semi-trailer.
Length, width, height
3-axle semi-trailers usually have a length of 13.6 meters, a width of 2.5 meters, and a height of 4 meters. The trailer has a large interior space to meet the requirements of transporting many goods for businesses.
Axles and wheels
3-axle semi-trailers are equipped with three axles, with each axle having a load capacity of 10 to 12 tons. Each axle is fitted with two wheels, so the total number of wheels on the semi-trailer is 6. The van's wheels are designed with high durability and heat resistance to ensure safety while driving on long roads.
Chassis
The semi-trailer chassis is designed with high-strength steel with a low weight. The chassis has a special design to reduce damage when transporting cargo. The chassis has a flat shape to provide more space for loading and unloading goods easily.
Hitch
The hitch of the van semi-trailer is located at the rear so that it can connect to the truck easily. The hitch is designed according to the international standard with high durability and safety.
To maintain a 3-axle van semi-trailer, users should pay attention to the following:
When selecting a 3-axle van semi-trailer for specific needs, consider the following factors:
Cargo Type and Size
Consider the type and size of cargo to be transported. A 3-axle refrigerated semi-trailer is ideal for transporting food products that require temperature control. A dry van trailer with a van design is suitable for general freight.
Towing Vehicle Compatibility
Ensure the semi-trailer is compatible with the towing vehicle in terms of weight capacity, hitch type, and trailer braking system. The towing vehicle should have enough power to tow the trailer safely, and the trailer should connect securely to the towing vehicle.
Weight and Capacity
Consider the trailer's Gross Vehicle Weight Rating (GVWR) and payload capacity. Ensure the trailer's weight and the cargo to be transported comply with local regulations and road restrictions. Overloading the trailer can affect safety, handling, and fuel efficiency.
Road Conditions and Terrain
Consider the road conditions and terrain where the trailer will be towed. For rough roads or off-road use, a semi-trailer with a rugged design and durable construction is suitable. In hilly or mountainous areas, a semi-trailer with good braking performance and load stability is required.
Loading and Unloading
Consider the loading and unloading methods and requirements. A semi-trailer with a low deck height and efficient loading/unloading equipment (such as ramps or tail lifts) is convenient for frequent loading/unloading operations. Ensure the trailer's design and features facilitate loading and unloading processes.
Security and Protection
Consider the security and protection needs of the cargo. A semi-trailer with good security features (such as locks, alarm systems) and protection against weather conditions (such as waterproof, UV-resistant materials) is essential for transporting valuable or sensitive goods.
Cost and Budget
Consider the initial cost of the semi-trailer, as well as maintenance, insurance, and fuel costs. Find a semi-trailer that fits the budget and provides an appropriate return on investment. Compare different models and brands to find the best value for money.
Brand and Supplier
Research the brand and supplier of the semi-trailer. Choose a reputable brand and reliable suppliers that provide quality products and good after-sales service. Read reviews and feedback from other customers to understand the quality and performance of the semi-trailer.
Legal Compliance
Ensure the trailer complies with all relevant regulations and standards, such as braking systems, lighting systems, reflectors, and more. Check the trailer's legal documents and certification to ensure it meets the requirements.
