The frame provides the structural support for the trailer, while the axles and suspension system help distribute the weight of the cargo and provide a smooth ride. The brakes are essential for slowing down and stopping the trailer, and the tires are critical for maintaining traction on the road. The lights ensure that the trailer is visible to other drivers, especially at night, and the coupling device connects the trailer to the truck.

3. How often should semi-trailer parts be inspected?

Regular inspections of semi-trailer parts are essential to ensure that everything is in good working order. It is recommended to inspect the trailer before and after each trip, as well as perform more thorough inspections on a regular basis.
