How high is a 13-meter trailer from the ground?
2 Answers
For a 13-meter tractor-trailer, according to national regulations, the cargo height of a truck should not exceed 4.5 meters from the ground. Therefore, the general loading height is only about 3.0 meters. Below is additional information: Truck: A truck, also known as a lorry, refers to a vehicle primarily used for transporting goods. Sometimes it can also refer to a vehicle capable of towing other vehicles, falling under the category of commercial vehicles. Generally, trucks can be classified into heavy-duty and light-duty based on their weight. The width of such vehicles is typically 2.4 meters. The maximum cargo weight for these vehicles is around 30 tons. Trailer: A trailer refers to a vehicle that is towed by a motor vehicle but has no power-driven device of its own. It consists of a combination of one motor vehicle (such as a truck, tractor, or forklift) and one or more trailers. Introduction: Trucks and tractors serve as the driving sections of a vehicle combination, known as the main vehicle. The towed sections are called trailers. They are an important type of vehicle for road transportation, and using vehicle combinations is one of the most effective and straightforward methods to enhance economic efficiency. They offer advantages such as speed, mobility, flexibility, and safety, and can easily facilitate sectional transportation.
I've been driving tractor-trailers for over a decade. The ground clearance of a 13-meter trailer's chassis is typically maintained between 40 to 60 centimeters, which is the most common range. The exact height depends on the vehicle's condition, such as the tire model and whether the tire pressure is sufficient. Smaller tires or lower pressure will cause the height to drop somewhat. The suspension system is also crucial—new springs with the right stiffness maintain stable height, while worn ones tend to sag. On long hauls, I pay special attention to this clearance. If it's too low when encountering potholes or construction zones, the chassis might scrape; if too high, it affects stability. I recommend checking tire pressure and suspension after each loading, keeping it around 50 cm for optimal balance. This ensures both fuel efficiency and safety, with no worries about bridge clearances. Regular maintenance helps prevent unexpected damage.
