- The type of trailer: There are different weight limits for different types of trailers, such as flatbed trailers, box trailers, and tanker trailers.
- The axle weight: The maximum weight that can be placed on each axle of the trailer is also regulated.
- The gross vehicle weight rating (GVWR): This is the maximum total weight of the trailer, including the weight of the trailer itself and the weight of the cargo it is carrying.
- The road conditions: The maximum weight may also be affected by road conditions, such as steep grades or narrow roads.
In the United States, the maximum weight that can be legally loaded into a trailer for a run is typically set by state regulations. These regulations vary from state to state, so it is important to check the specific regulations for the state in which the trailer will be operated.
As an example, here are the maximum weight limits for some common types of trailers in the state of California:
- Flatbed trailer: 80,000 pounds
- Box trailer: 80,000 pounds
- Tanker trailer: 90,000 pounds
It is also important to note that there may be additional weight restrictions for certain types of cargo, such as hazardous materials. It is the responsibility of the carrier to ensure that the weight of the cargo does not exceed the legal limits.
