Purpose and Use Case
Single axle tractors, commonly day cabs with one drive axle (single screw), are gaining attention for towing construction equipment such as 10-ton shovels and skid steers. Operators seek cost-effective, manageable rigs that can haul loads approximately 30,000 to 35,000 pounds combined with trailers weighing around 10,000 pounds. This approach is driven by the high costs and limited availability of tandem axle tractors or heavy duty dual-drive trucks.
Advantages of Single Axle Tractors
Operators often pair single axle tractors with lightweight step deck or lowboy trailers capable of carrying the equipment and attachments in one trip, streamlining logistics and reducing downtime.
Terminology
Many contractors report great satisfaction with single axle tractors for hauling smaller construction machinery cost-effectively. Operators emphasize precise load planning, use of tri-axle trailers, and appropriate suspension setups to optimize performance and safety. For urban jobs or regional hauling, a single axle rig strikes a good balance between capability and costs.
Conclusion
Choosing a single axle tractor for hauling 10-ton shovels and skid steers offers an affordable, fuel-efficient, and nimble solution for many construction transport needs. While it demands careful attention to load limits and stability, the benefits in reduced acquisition cost and operating expenses make it a pragmatic choice for contractors focusing on moderate weight hauled equipment and maneuverability in tighter work environments.

Advantages of Single Axle Tractors
- Lower Purchase and Operating Cost: Single axle tractors are generally cheaper both new and used, offering savings compared to tandem axle or twin screw units.
- Fuel Efficiency: Reduced mechanical drag and fewer drivetrain components result in 2.5-5% fuel savings compared to tandem setups.
- Improved Maneuverability: Smaller size and reduced axle count enhance urban and tight-area navigation.
- Simplicity: With fewer parts, maintenance and repairs can be less expensive.
- Adequate for Moderate Loads: Compatible with tri-axle trailers, single axle tractors can legally haul payloads up to approximately 65,000 lbs gross combined weight (GCW), meeting many construction transport needs.
- Weight Limits: Single axle tractors limit gross vehicle weight and place greater load on the single drive axle (often limited to 20,000 lbs), requiring careful load distribution.
- Reduced Stability: On uneven or rough roads, lack of a tandem drive axle can result in less stability and traction.
- Application Suitability: Best suited for linehaul or medium-distance hauling; heavy off-road use or very heavy loads still favor dual or tandem drive configurations.
- Tire Wear: Higher load concentration can cause increased tire wear without proper management or axle weighting.

Terminology
- Single Screw: A truck with a single drive axle.
- Dually: Truck with dual rear wheels on each side of the drive axle.
- Tri-Axle Trailer: Trailer with three axles allowing greater load distribution.
- Gross Combined Weight (GCW): Combined weight of the truck, trailer, and payload.
- Load Distribution: Proper allocation of weight across axles to meet legal and safety standards.
