Measuring the wheelbase of a semi-truck is essential for many reasons such as determining the correct trailer length, calculating weight distribution, and ensuring compliance with federal and state regulations. It’s a simple process that requires some basic tools and attention to detail. In this article, we’ll guide you through the steps on how to measure semi-truck wheelbase.
Step 1: Park the Truck on a Flat Surface
To get an accurate measurement, park the semi-truck on a flat surface. Make sure the truck is level and straight before proceeding to the next step. This way, you’ll avoid any variations in the measurement due to uneven ground or a tilted truck.
Step 2: Locate the Center of the Front Wheel
The first thing you need to do is locate the center of the front wheel. Use a tape measure or a ruler to measure the distance from the center of the front wheel to the back of the truck’s cab. This is the distance between the front axle and the rear of the cab.
Step 3: Locate the Center of the Rear Axle
The next step is to locate the center of the rear axle. Measure the distance from the center of the rear axle to the center of the front axle. This is the wheelbase of the truck.
Step 4: Measure the Distance Between the Rear Axles
Some semi-trucks have more than one rear axle. If your truck has more than one rear axle, measure the distance between the centers of the two rear axles. This measurement is also important for weight distribution purposes.
Step 5: Check for Compliance with Federal and State Regulations
It’s essential to check if your semi-truck complies with federal and state regulations. Each state has different regulations regarding the maximum allowable length of a semi-truck and trailer. Also, the weight distribution must be within the legal limits. Check your state’s transportation department website or contact them to get the necessary information.
By following the above steps, you can measure the wheelbase of your semi-truck accurately. Remember to check the compliance with federal and state regulations to avoid any penalties.
