This section will review various types of semi-trucks, such as single-axle and double-axle trucks, and their respective hauling limits.

Understanding the hauling limits of different semi-truck types equips truck drivers and transportation companies to select an appropriate truck for their specific transportation needs. This ensures that the selected truck remains compliant with weight regulations, maintains safety on the roads, and promotes efficient transportation.

Single Axle Semi Trucks: Load Limitations

Single-axle semi-trucks, often used as delivery trucks, have a lower hauling capacity, typically up to 20,000 pounds, making them suitable for smaller shipments and shorter distances. These trucks are generally lighter than their double-axle counterparts and are subject to different weight restrictions, such as a maximum weight capacity of 20,000 pounds and an average length of 19 feet 6 inches. When carrying an empty trailer, single-axle semi-trucks are even more fuel-efficient and easier to maneuver. To ensure compliance with regulations, it’s important to consider the semi truck weigh before hitting the road.

Despite having a lower hauling capacity than double-axle trucks, single-axle semi-trucks still play an important role in the transportation industry. Their suitability for smaller shipments and shorter distances makes them a valuable asset for businesses that require efficient transportation for lighter loads.

Double Axle Semi Trucks: Enhanced Carrying Power

Double-axle semi-trucks, also known as heavy duty trucks, have the following advantages:

They can carry more weight, up to 34,000 pounds, making them ideal for larger shipments and long-distance transportation.
The weight distribution across multiple axles allows for a larger portion of the load to be supported by the truck’s frame.
The use of double tires in the rear of the truck provides enhanced stability and traction, further contributing to its carrying capacity.

Understanding the hauling limits of double-axle semi-trucks helps truck drivers and transportation companies to select the right truck for their specific transportation needs. This ensures that the selected truck remains compliant with weight regulations, maintains safety on the roads, and promotes efficient transportation for heavier loads.
