Different Types of Semi-Truck Axle Trailers

Now that we’ve answered, “How many axles does a semi-truck have?”, we want to go over the different types of semi-truck axle trailers. Truth be told, there are many different kinds, so we’re just going to go over some of the most common ones today. However, rest assured that when you opt for a new International truck from our inventory, it’ll have all the grunt you need to tackle almost any trailer. With that being said, let’s take a look at the different types of semi-truck trailer axles:

• Tandem Axles: You’ll find tandem axles on most semi-trailers. Tandem axles simply refer to the two axles spaced right behind one another. Most of the time, they’re about five feet apart and can sometimes be moved forward or backward to support weight where needed.
• Spread Axles: Spread axles are also known as split tandem axles. Semi-trailers with spread axles have single axles spaced out about 10 feet apart from each other.
• Lift Axles: Lift axles provide drivers with the ability to raise and lower the axle for easier control. Most lift axles use airbags or springs to lift and lower the axle.
• Triple Axles: Most commonly, you’ll see triple axle trailers on dump trucks. They likely include a tandem drive axle with an air-lift third axle, hence the name triple axle.
