Everything You Need To Know About Semi Trailer Dimensions

With transport, dimensions are important both for the equipment being shipped, and the trailer hauling it. Based on the size, shape, and weight of the equipment, the best type of trailer is determined for safe transport. There are a wide variety of trailers, and each have their own specific set of dimensions. Knowing semi trailer dimensions helps determine what they can and can not transport. For instance, any equipment over 48,000lbs can not be transported on a standard flatbed trailer. Instead, a removable gooseneck (RGN) trailer may be more suitable for hauling, because it holds up to 150,000lbs.

Knowing the semi trailer dimensions, and their max weight, helps ensure that the equipment transport is done properly. When it comes to equipment transport, you always want to follow best practices and adhere to top safety standards for the best possible transport experience. Below, we’re going to discuss some common types of trailers, along with their dimensions, so you have a better understanding of which trailer type may be the best for your equipment transport.

The Most Common Types of Trailers and Their Dimensions:

Flatbed Trailer Dimensions

Flatbed trailers are one of the most common types of semi trailers used for equipment transport. They’re versatile in that they can carry an LTL load, such as a forklift or large pieces of machinery. When it’s an LTL load, this allows the driver to haul multiple freight from multiple clients, which can help reduce costs. Check out the flatbed trailer dimensions below.

Max Length: 53 ft.
Max Width: 8.5 ft.
