How to Ship an Articulated Dump Truck: Complete Transport Guide
Articulated dump trucks (ADTs) are among the most challenging pieces of construction equipment to transport — they're long, wide, heavy, and their articulated frame means they can't simply be chained down like a rigid machine. A Caterpillar 725 ADT, for example, measures 32 ft 5 in long, 9 ft 6 in wide, and 11 ft 3 in tall at an operating weight of 50,000 lbs — well into oversize territory. Larger models like the Cat 745 stretch to nearly 38 ft long and weigh over 73,000 lbs. Getting an ADT from point A to point B requires the right trailer, the right permits, and a carrier who understands the machine's unique loading requirements.
Articulated Dump Truck Dimensions and Weight Ranges
ADTs vary significantly by model and manufacturer. Here are representative specs for common models:
| Model | Length | Width | Height | Operating Weight |
|---|---|---|---|---|
| Cat 725 | 32 ft 5 in | 9 ft 6 in | 11 ft 3 in | ~50,000 lbs |
| Cat 725C2 | 34 ft 7 in | 9 ft 8 in | 12 ft 5 in | ~50,795 lbs |
| Cat 745 | 37 ft 11 in | 11 ft 1 in | 12 ft 5 in | ~73,553 lbs |
| Volvo A40G | ~38 ft | ~10 ft 6 in | ~12 ft | ~75,000 lbs |
| John Deere 410E | ~35 ft | ~10 ft | ~11 ft 6 in | ~55,000 lbs |
Most ADTs exceed the 8.5 ft federal width threshold, making oversize permits mandatory in every state. Larger models like the Cat 745 at 11 ft 1 in wide require two pilot cars in most states.
Trailer Requirements for ADT Transport
The articulated frame of an ADT creates unique loading challenges. The machine cannot be loaded with the frame locked in a straight position — the hitch point must be properly supported during transport to prevent frame stress. Key trailer considerations:
- RGN (Removable Gooseneck): The preferred trailer for most ADTs. The detachable neck allows the machine to drive on under its own power, which is critical for ADTs — their articulated steering makes crane loading difficult and risky. An extendable RGN (29–53+ ft) accommodates the length of larger models.
- Lowboy: Can be used for ADTs that can be loaded with a crane or ramps, but the articulated frame makes this more complex. The low deck height (18–24 inches) is essential for keeping total load height within permit thresholds.
- Deck Length: Larger ADTs (Cat 745, Volvo A40G) at 37–38 ft require an extendable RGN or a stretch lowboy to accommodate the full machine length.
Permit Requirements for ADT Transport
Because virtually all ADTs exceed 8.5 ft in width, oversize permits are required in every state traversed. Width-based permit requirements:
- 8.5–12 ft wide: Oversize permit required; no escort in most states.
- 12–14 ft wide: One pilot car required in most states.
- Over 14 ft wide: Two pilot cars required in most states; some states require a law enforcement escort.
Weight-based permits are required when GVW exceeds 80,000 lbs. A Cat 745 at 73,553 lbs operating weight plus a 40,000 lb trailer tare weight easily exceeds this threshold, requiring axle weight distribution analysis and potentially additional trailer axles.
Loading and Tie-Down Considerations
Proper loading of an ADT requires attention to the articulation joint. Best practices:
- Drive the machine onto the RGN under its own power — this is the safest and most common method.
- Lock the articulation joint before securing the machine. Most ADTs have a frame lock pin or bar for transport.
- Use a minimum of 4 chains (Grade 70 or higher) with binders, placed at the manufacturer's designated tie-down points — typically the front axle area and rear frame.
- Lower the dump body to its lowest position to reduce height and center of gravity.
- Remove any attachments (rock ejectors, tailgates) that add width or height if they push the load into a higher permit tier.
Cost Factors for ADT Transport
ADT transport costs are driven by machine size, distance, permit complexity, and escort requirements. Larger machines (Cat 745, Volvo A40G) at 11+ ft wide require two pilot cars, which can add $400–$800 per day to the move cost. Multi-state moves require individual permits for each state, typically $150–$300 per state. Fuel surcharges and accessorial fees (loading assistance, tarping) also apply.

Common questions
What trailer do I need to ship an articulated dump truck?
An RGN (Removable Gooseneck) is the preferred trailer for most ADTs. The detachable neck allows the machine to drive on under its own power, which is important because the articulated frame makes crane loading difficult. An extendable RGN accommodates larger models like the Cat 745 at nearly 38 ft long.
Do articulated dump trucks require oversize permits?
Yes. Virtually all ADTs exceed the 8.5 ft federal width threshold — a Cat 725 is 9 ft 6 in wide, and a Cat 745 is 11 ft 1 in wide. Oversize permits are required in every state traversed, and loads over 12 ft wide require pilot cars.
How do I secure an articulated dump truck for transport?
Lock the articulation joint using the manufacturer's frame lock pin or bar before loading. Use a minimum of 4 Grade 70 chains at the designated tie-down points (front axle area and rear frame). Lower the dump body to its lowest position to reduce height and center of gravity.
How much does it cost to ship an articulated dump truck?
Cost depends on machine size, distance, and permit requirements. Larger ADTs over 12 ft wide require pilot cars ($200–$400 per escort per day). Multi-state permit costs typically run $150–$300 per state. Contact IronHaul for a specific quote based on your machine's dimensions and route.
Can a Cat 745 articulated dump truck be shipped on a standard lowboy?
A Cat 745 at 37 ft 11 in long and 11 ft 1 in wide requires an extendable RGN or stretch lowboy. Standard 48 ft lowboys may not accommodate the full length, and the 11 ft width requires two pilot cars in most states.
