How Is Weight Distributed on a Semi Truck?

Semi-trucks are large haulage vehicles that are used to transport goods across long distances. Semi-trucks, also known as ‘18-wheelers’, ‘semis’, or ‘big rigs’, are commonly seen on the roads in North America. They are an essential part of many businesses, and as such it is important to understand how weight is distributed on a semi-truck.

When loading up a semi-truck with cargo, the weight must be distributed properly in order for the vehicle to be safely driven and for all laws and regulations to be followed. The total weight of the cargo must not exceed the Gross Combination Weight Rating (GCWR) of the semi-truck and trailer combination. The GCWR is the maximum allowable weight limit of both vehicles combined and is determined by subtracting the weight of the tractor from its maximum loaded capacity.

The most important factor when distributing weight on a semi-truck is ensuring proper axle loading. Axles must be loaded so that they do not exceed their individual Gross Axle Weight Ratings (GAWR).

The GAWR can be found in the vehicle’s owner’s manual or from its manufacturer. Exceeding this limit can cause serious damage to tires and axles, leading to costly repairs or accidents.

Weight should also be distributed evenly between both sides of the truck’s frame. This will keep it balanced and help prevent it from tipping over or being pushed off course by strong winds or steep inclines. In addition, weight should not be concentrated at either end of the trailer; this could cause difficulty when turning corners.

Conclusion:

Weight distribution on a semi-truck is an important factor in ensuring that it can safely transport cargo over long distances. All axles must not exceed their individual Gross Axle Weight Ratings (GAWR), while also being evenly distributed between both sides of the truck frame. This will help to keep it balanced and prevent any potential accidents due to heavy loads.
