How to Ship an Articulated Dump Truck: Complete Transport Guide

Articulated Dump Truck Specifications by Model

ADTs are manufactured by Caterpillar, Volvo, Komatsu, Bell, and Doosan, with specifications varying significantly by model and payload class:

Model	Payload Class	Empty Operating Weight	Length	Width	Height
Cat 725	25 ton	~50,000 lbs	32 ft 5 in	9 ft 6 in	11 ft 3 in
Cat 730	30 ton	~51,831 lbs	34 ft	9 ft 8 in	11 ft 6 in
Cat 745	45 ton	~72,995 lbs	37 ft	10 ft 2 in	12 ft
Volvo A30G	30 ton	~48,500 lbs	33 ft	9 ft 4 in	11 ft 2 in
Komatsu HM300	30 ton	~50,700 lbs	33 ft 6 in	9 ft 6 in	11 ft 4 in

Note: Always verify exact specifications for your specific machine — options, liners, tailgates, and fuel levels significantly affect actual transport weight.

Why ADTs Almost Always Require Permits

Articulated dump trucks exceed standard legal limits in multiple dimensions:

• Width: Most ADTs are 9.5–10.5 ft wide — well over the 8.5 ft legal limit. Oversize permits are required in all states.
• Weight: ADTs at 50,000–73,000 lbs empty exceed the 80,000 lb GVW threshold when loaded on a trailer. Overweight permits are required for most configurations.
• Height: ADTs at 11–12 ft tall are within legal height limits (13.5 ft federal standard) when loaded on a lowboy with an 18–24 inch deck height, resulting in a total height of approximately 12.5–13.5 ft.

Trailer Selection for Articulated Dump Trucks

• RGN (Removable Gooseneck) Trailer: The preferred option for operational ADTs. The detachable gooseneck allows the ADT to be driven directly onto the trailer deck, eliminating the need for ramps. This is the safest and most efficient loading method for ADTs.
• Lowboy Trailer: An alternative to RGN for ADTs. The low deck height (18–24 inches) keeps the total loaded height within legal limits. Loading requires ramps, which must be rated for the ADT's weight and approach angle.
• Multi-Axle RGN: Required for larger ADTs (Cat 745 class at ~73,000 lbs) to distribute weight within state bridge formula requirements. A 5-axle or 7-axle configuration may be needed depending on state requirements.

The Articulation Joint: Critical Securement Requirement

The articulation joint between the cab and dump body is the most important securement consideration for ADT transport. During transport, the articulation joint must be locked to prevent the machine from "jackknifing" on the trailer:

• Steering-frame lock: Most ADTs have a manufacturer-provided steering-frame locking device (a pin or bar) that locks the articulation joint in the straight-ahead position. This device must be installed before loading.
• Verify lock installation: Confirm the steering-frame lock is properly installed and secured before the machine is driven onto the trailer. An unlocked articulation joint can cause the machine to shift dangerously during transport.
• Manufacturer instructions: Follow the specific manufacturer's instructions for steering-frame lock installation. Procedures vary by brand and model.

Dump Body Preparation

The dump body must be properly prepared before transport:

• Empty the body: The dump body must be completely empty and free of debris, dirt, or aggregate. Residual material adds weight and can fall during transport, creating a road hazard.
• Lower the body: The dump body must be fully lowered to the transport position. A raised dump body significantly increases the machine's height and center of gravity.
• Secure the tailgate: Lock the tailgate in the closed position to prevent it from opening during transport.

Tie-Down Requirements for ADTs

FMCSA regulations require proper load securement for ADTs:

• Minimum 4 chains or straps — two at the front frame and two at the rear frame
• Use manufacturer-designated tie-down points on the main frame only
• Chain working load limits must total at least 50% of the cargo weight
• For a 50,000-lb ADT, minimum total chain WLL is 25,000 lbs
• Wheel chocks placed in front of and behind all tires

Non-Operational ADT Transport

Non-operational ADTs that cannot be driven onto the trailer require crane or winch loading. This adds cost and complexity to the transport. When requesting a quote for a non-operational ADT, inform IronHaul of the machine's condition so we can dispatch the appropriate loading equipment.

IronHaul Logistics transports articulated dump trucks of all sizes and brands nationwide. We handle all permits, coordinate pilot cars, and ensure proper articulation joint locking before every move.
