How is the Approved Load Capacity Calculated?

Approved load capacity can be checked on the vehicle's registration certificate. The approved load capacity refers to the inspection and regulation by traffic authorities of the maximum allowable load capacity for a vehicle on dry and hard roads, which is essentially the vehicle's tonnage, identical to the tonnage registered on the vehicle's registration certificate. More information on approved load capacity is as follows: 1. The total mass of a truck is the maximum loading mass when the vehicle is operating on the road. Different types of vehicles calculate total mass in different ways. The total mass of a truck is the curb weight (vehicle weight) + the weight of the driver and assistant + the weight of the cargo. Compared to the approved weight, the difference lies in that the total weight is the truck's weight plus the weight calculated from people and objects, while the approved weight is the capacity the truck can bear, i.e., its load-bearing capacity. 2. For nationally standardized or imported motor vehicles, the load capacity should be recognized according to the original vehicle's instruction manual. For modified motor vehicles, the load capacity should be determined by referring to the minimum values of engine power, chassis strength, tire load capacity, and the original vehicle's mass. The load capacity of trailers should be verified by referring to the method for modified vehicles.
As a small truck owner, the rated load capacity isn't something we calculate ourselves—it's predetermined by the manufacturer before the vehicle leaves the factory. Every time I haul cargo, I first check the number on the vehicle nameplate or the registration certificate—that's the maximum allowable load. For example, my truck is marked for 500 kg. Overloading makes the vehicle unstable, increases tire pressure (raising the risk of blowouts), and wastes fuel. Once, I overloaded with some construction materials, and the truck's braking response slowed dangerously on the highway—nearly causing an accident. Later, I got smarter: now I weigh the cargo with a simple scale before loading. If you're unsure about the load limit, ask a professional repair shop or check the manual—don't risk exceeding it. After adopting this habit, my truck's suspension system wears much less, extending its lifespan. Safety first—ensuring both people and the vehicle stay safe.
I've been driving trucks for transportation for many years, and the rated load capacity is our bottom line. It's not calculated by us, but determined by the manufacturer based on chassis design and testing. I strictly adhere to that value, otherwise, overloading leads to high fines if caught, and the vehicle wears out faster. My experience is to check the cargo weight before departure, not relying on visual estimation but using scales or volume conversion. When overloaded, steering becomes less responsive, especially on mountain roads where it's prone to losing control. I maintain my vehicle regularly to ensure the suspension and brakes are in good condition. Remember, compliant driving not only protects yourself but also takes responsibility for the road and other vehicles. Don’t overlook this in daily use; developing good habits makes the journey safer.
As a driving enthusiast, I understand that the rated load capacity is a safety indicator determined during vehicle design. It is established by manufacturers through structural tests such as load-bearing simulations, and cannot be directly calculated by users. We can only verify the figure through the nameplate or vehicle documentation. Overloading can damage the suspension and shorten the vehicle's lifespan. Maintaining a load within limits is crucial—safety should always come first.
