What Is a Semi Trailer? Complete Guide by Nova Trailer
Introduction
A semi trailer is one of the most essential vehicles in modern transportation and logistics. It is designed to carry heavy loads efficiently and safely across long distances. At Nova Trailer, we specialize in manufacturing high-quality semi trailers that meet international standards for performance, durability, and safety.
What Is a Semi Trailer?
A semi trailer is a trailer without a front axle. It is connected to a tractor unit (truck head) through a fifth-wheel coupling. The front part of the semi trailer rests on the tractor, while the rear part runs on its own axles. This design allows for excellent maneuverability and weight distribution, making semi trailers ideal for carrying heavy or large loads.
How Does a Semi Trailer Work?
The semi trailer and the truck head together form a tractor-trailer combination. When coupled, the truck pulls the semi trailer and provides steering, power, and braking. The trailer carries the cargo. When uncoupled, the semi trailer stands on its landing legs, ready to be reattached to another truck if needed.
