The back part of a semi truck is commonly known as the trailer or semitrailer. It is a large, flatbed trailer with no front axle that is attached to the semi truck cab (also known as the tractor) via an articulating connection.
The trailer and tractor form an articulated vehicle, allowing the two parts to move independently of each other while still being connected. This allows for maneuverability and stability on roads and highways.
Truck trailers come in all shapes and sizes, depending on the type of cargo they are designed to carry. Flatbed trailers are the most common type, but there are also specialty trailers such as tankers, reefers (refrigerated trailers), car carriers, lowboys, drop decks and many more. All of these types have their own specific purposes for carrying different types of cargo.
The trailer is controlled by the driver from inside the cab of the tractor through a fifth wheel connection. The fifth wheel is a mechanism that allows for movement between the tractor and trailer when turning or maneuvering. This connection point also helps to keep both parts in line when traveling down roads and highways.
Safety
The back part of a semi truck holds an important role in its overall safety. It is essential that all connections between the tractor and trailer be properly inspected before every trip to ensure they are secure. Properly maintained brakes on both parts are also essential to ensure safe operation while driving.
Conclusion
In conclusion, what do you call the back part of a semi truck?
The back part is commonly referred to as either a trailer or semitrailer and it attaches to the cab (or tractor) via an articulating connection point called a fifth wheel. This connection point allows for movement between both parts while still remaining secure during travel down roads and highways. Safety should always be taken into consideration when operating this type of vehicle by ensuring that all connections are tight and brakes are properly maintained.
