One of the most common trailers you might see out on the roads.

Length: 48’ – 53’ Long deck
Width: 8’ 6”
Height: Deck Height 60” (5’)
Weight Capacity: 48,000lbs

These are mainly used for hauling loads of material and equipment.

Also known as a Single Drop

Length: 48’ – 53’ most common. There are some variations though with these trailers ranging from 35’ – 63’ the top deck or neck will be typically 11’ long with the lower deck 37’ – 42’ and sometimes longer. Trailers can be Tandem or Tridem and that can change the allowable weight capacity.
Width: 8’ 6”
Height: Deck height 60” and the bottom deck typically 42”
Weight Capacity: 43,000lbs – 62,000lbs

The lower deck can accommodate loads that are too tall to be transported using a flatbed/highboy, but still, need the length. A good example would be, Telehandlers, Loaders, Construction Equipment. These trailers are easy to load and unload.

Also known as a lowboy, or double drop lowboy, and detachable’s

Length: 48’ Long, the upper decks typically 6’ – 10’ and the lower deck (bottom well) about 30’ – 32′
Width: 8’ 6”
Height: 18” to 24“
Weight Capacity: 43,000 lbs – 58’000lbs depending upon number of axles. Expendables can carry even greater weight and have longer wells.

The trailers can typically carry the tallest loads. These are used to haul Construction equipment, Wheel Loaders, Rock Trucks, Bulldozers, oversized/large vehicles, tanks, cranes etc. Typically, loading from the rear. Some Trailers will also feature ramps known as Beaver Tails. Attached at the rear of the trailer and stowed vertically.

Length: 24’ – 29’ main deck
Width: 8’ 6”
Height: 18” to 24“
Weight Capacity: 42,000 lbs – 150,000 lbs dependent on the Lowboy trailer and number of axles.

RGN’s can be double drops and lowboys, so RGN trailers do vary quite a bit. This type of trailer neck can be removed. Allowing the Semi Truck to detach from the trailer, lowering the trailer, so it can then act as a ramp. The equipment gets loaded at the front of the trailer and is very low. Typically, used to transport long heavy motorized equipment, such as Bulldozers or Excavators, for example.

You might hear the driver talk about booster jeeps. In short, when a driver is hauling a very heavy load, they are required to spread the weight in order to not damage the road or wreck their equipment. Using extra wheels or booster jeeps, allows the driver to safely haul heavy loads without breaking laws and, being unsafe, or damage the roads. These can attach to the semi-truck directly, then the loaded trailer attaches to the booster, you may even find another booster on the tail of the loaded trailer too.
