A tractor unit, a detachable front-axle assembly known as a dolly, or the tail of another trailer support a major percentage of a semi-weight. The trailer's When a trailer is uncoupled, it is usually equipped with landing gear (legs that may be lowered).

Many trailers have relocatable (repositionable) wheels that can be completely uninstalled to better distribute the load to bearing wheel weight components. Semi-trailers, which have both front and rear axles, are more popular 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 dolly, which is already linked to the second semi-trailer, is connected to the first semi-trailer with a drawbar. A list of the various types of semi-truck trailers can be seen below.

Types of trailers

     ● Flatbed trailers

Several lengths and configurations are only permitted to drive on turnpike/toll roads, which are significantly too long for most roads. The body and frame might be one of three general designs: full steel, generally with wood planks, is the heaviest and most durable.

The ever-popular steel frame and aluminum bed combination. These have a wood component for nailing down dunnage boards, as well as an aluminum portion. Which is the lightest, allowing more material to be transported legally without the need for overweight permits?

● Lowboy trailer

A lowboy is a semi-trailer with two deck height drops one after the gooseneck and another before the wheels. In comparison to other trailers, this permits the deck to be incredibly low. It can transport legal loads up to 12 feet (3.66 meters) tall, whereas other trailers can't. Lowboys are used to transport big equipment like bulldozers and industrial machinery.

Lowboys are made to carry a lot of weight. Lowboy trailers with two axles can carry a maximum weight of 40,000 pounds. Lowboys can cost up to 80,000 dollars depending on how many axles are used.

Operating lowboy trailers may necessitate additional licenses. Regulations set forth by the state or municipality should be rigorously adhered to.

● Reefer trailer

Refrigerated trailers are essentially dry van trailers with a refrigeration system and insulation to keep the products inside fresh. Semi-trailers of this sort are primarily used to transport frozen foods and produce. Pharmaceuticals are sometimes transported in reefer trailers. Refrigerated trailers have the same maximum weight as dry vans

Reefer trailers can carry up to 45,000 pounds of cargo. The maximum length of a refrigerated trailer is 48 to 53 feet.

● Step deck trailer

The main difference between step-deck semi-trailers and flatbed trailers is that the maximum fright height must be less than 10 feet. Step decks were created to transport items that a flatbed trailer couldn't. The majority of this is due to height constraints.

A step-deck or drop-deck trailer is another name for it. Lengths of 48 to 53 feet are the maximum permissible dimensions. The maximum width of a step-deck trailer is 8.5 feet, while the maximum allowable freight height is 10 feet. The greatest weight that can be supported by the step-deck is 48,000 pounds.
