Semi-trucks offer multiple varieties of trailer options to choose from. The type of cargo needed to transport and the payload size determines the size and style of the trailer. The tractor unit or detachable front-axle assembly known as a dolly or a trail of another trailer supports a significant percentage of a semi trailer’s weight. When a trailer is uncoupled, it is equipped with landing gear to support it.
Most trailers have repositionable wheels that can be uninstalled to better distribute the load to bearing weight wheel components. Semi-trailers, which have both front and rear axles, are more commonly used for transport than full trailers. One of the semi’s best features is its ease of backing.
The tractor’s fifth wheel coupling connects the first semi-trailer to the power unit, while the converter trolly, already linked to the second semi-trailer, connects to the first semi-trailer with a drawbar. Check the complete list of semi-trailer types outlined below.
Types of trailers for semi-trucks
• Flatbed trailers
These trailers are popular and the most common semi-trailer use today. Flatbed trailers are primarily used for shipping construction material and various equipment. Several lengths and configurations of these trailers are only permitted to drive on turnpike or toll roads, which are significantly too long for most roadways. These trailers have a wood component for nailing down dunnage boards and an aluminum portion, allowing more material to be transported legally with overweight permits.
• Lowboy trailers
These trailers sit low to the ground, allowing them to carry very tall freight. It can transport legal weight up to 12 feet tall compared to other trailers. Lowboys tend to transport large equipment like bulldozers and industrial machinery. In addition to their weight, these trailers can carry a maximum weight of 40,000 pounds.
