What is the height limit for a 13-meter trailer?
2 Answers
For a 13-meter tractor, according to national regulations, the cargo height of a truck must not exceed 4.5 meters from the ground, so the general loading height is only about 3.0 meters. A 13-meter semi-trailer, as per national standards, typically has a maximum load capacity of 34 tons. Below is relevant information: 1. Characteristics of semi-trailers: A semi-trailer is a trailer with its axles placed behind the vehicle's center (when the vehicle is evenly loaded) and equipped with a coupling device that transmits horizontal and vertical forces to the tractor. It is a heavy-duty transport vehicle connected to the semi-trailer head via a kingpin. The national standard allows a total weight of 55 tons including the trailer's own weight, but the trailer's load capacity can reach up to 200 tons. 2. Classification of semi-trailers: Semi-trailers are generally three-axle trailers, categorized into types such as 11-meter warehouse-barrier semi-trailers, 13-meter warehouse-barrier semi-trailers, and low-flatbed semi-trailers. Vehicles with load capacities and dimensions similar to ordinary high-barrier trucks but weighing 15% or more lighter are defined as light-duty. 3. Load capacities of different vehicle types: A 6.8-ton self-weight vehicle can carry about 40 tons, and a 7.2-ton self-weight vehicle can carry about 50 tons.
From a safety perspective, the height limit for 13-meter trailers is set at around 4 meters on most roads in China. This standard isn't arbitrary—it's designed to prevent collisions with bridges, tunnels, or cable facilities, which could otherwise cause serious accidents or traffic jams. I remember once seeing a driver who didn't notice the height limit sign; the roof of his vehicle scraped against a bridge guardrail, costing thousands in repairs and resulting in fines and penalty points from traffic police. When driving, I always recommend checking the vehicle's height in advance. After loading the cargo, use a tape measure to check the distance from the ground to the roof to ensure it doesn't exceed 4 meters. Also, pay attention to height limit signs along the route, especially at highway entrances and ramps. Developing this habit can save you trouble and money while ensuring safer journeys.
