Tanker Truck Dimensions
How long is a tanker trailer? Tanker trailers are generally 36 – 43ft long. There are other sizes, but should be within the standards set by the International Organization for Standardization (ISO). Tanker trailers of different lengths have different volumes. For example, a 36ft tanker trailer has a volume of 10500- 12500 gallons and we support customization within this range. Of course, the length of the tanker trailer is not limited to 43ft.
Reminder: If you have special needs, we can also make longer tanker trailers. But we don’t recommend it, as a longer semi-trailer means more difficult turns and a greater chance of an accident.

Lowbed Trailer Dimensions
Lowbed trailers are used to transport large and heavy equipment, and some customers are also used to transport containers. Length between 36-56ft (including ladder). The lowbed trailer has a strong carrying capacity and a low center of gravity, so it is suitable for transporting heavy-weight cargo. In order to lower the center of gravity, its cargo platform is designed to be lower than the gooseneck connecting the tractor. There are two types of low-bed semi-trailers: mechanical ladders and hydraulic ladders.
Dimensions of lowbed trailers in different lengths:
|Lowbed Trailer Dimensions||Total length(ft)||Width(ft)||Total height(ft)||Deck height(ft)||Tare weight(T)||Max payload|
Skeletal Trailer Dimensions

Taller like a fence cargo trailer, its fence structure can be as high as 13.8 feet. In fact, each kind of semi-trailer can be customized. Before starting production, we draw drawings according to the requirements of customers. After the customer confirms, we will manufacture semi-trailers according to the drawings.
When you are confused about how tall is a tractor trailer, you can use the table below to know what the height of different types of semi-trailers is.

Container semi-trailers such as skeleton semi-trailers and flat-bed semi-trailers are generally determined according to the size of the container to be transported. A standard container is 7.7 feet wide. If it is a non-standard customized container, we can also customize the width of the container semi-trailer for you within the standard range of the semi-trailer. There is also a semi-trailer whose width can be extended. A widener is installed on its side, and one side can expand the width of 25cm, and the width of the semi-trailer will be expanded by 50cm when the wideners on both sides are fully expanded.

How Heavy Is a Semi Trailer?
The main part of the semi-trailer is mostly made of carbon steel and weighs about 7-8 tons. The quality of the semi-trailer also has a certain relationship with its own weight. The heavier the semi-trailer, the stronger the structure and the higher the quality. However, if the self-weight of the semi-trailer is too heavy, it will reduce the cargo carrying capacity, increase fuel consumption, and reduce revenue.
Therefore, it is very important to design the structure of the semi-trailer reasonably.
In addition to carbon steel semi-trailers, there are also some semi-trailers made of aluminum alloy. The quality of this semi-trailer is lighter, but the price is also higher. For detailed information about semi-trailer weight, please read the table below:
|Skeleton Trailer||4.6 – 5.8|
|lowbed Trailer||6.1 – 13.5|
|Flatbed Trailer||5.0 – 8.3|
|Side Wall Trailer||5.3 – 8.5|
|Livestock Trailer||5.3 – 8.7|
