ADTs: compare specs, models, and performance

While the tasks of ADTs may seem simple (move material from point A to point B), the options that go into selecting the right machine can have an outsized impact on the machine's productivity, uptime, and longevity, all of which are significant to your bottom line. 

ADTs combine the functions of hauling, transporting, and dumping heavy loads — usually in challenging environments like construction, mining, and quarrying. These machines can often be favourable to rigid dump trucks due to their manoeuvrability in rough terrain and keeping wheels grounded for traction, excelling in steep grades. 

However, models can vary greatly in size, operating weight, turning radius, suspension type, and even in boosted safety features. Compare the latest ADTs from top manufacturers in North America with our comprehensive spec guide and see how each model stacks up in terms of performance. 

1. Liebherr 

Liebherr's ADT is engineered for productivity, durability, and performance in the most demanding off-road conditions. The TA 230 Litronic is the first model in the lineup and represents Liebherr's entry into the ADT market. It combines high payload capacity, powerful driveline technology, and intelligent assistance systems to support safe, efficient haul operations across a variety of industries including construction, mining, and quarrying.

2. Volvo Construction Equipment 

Volvo Construction Equipment fully revamped its ADT lineup in 2025. An updated frame and body design sheds material farther from the truck, minimizing the support equipment needed.

A new electronic system on all models and a new transmission on the largest models reduce fuel consumption, and the drivetrain can be adapted to future technologies. Terrain memory, automatic drive, 100 percent differential locks, an all-terrain bogie, and hydro-mechanical steering provide traction and stability.

Volvo Dynamic Drive offers predictive gear selection that adapts to conditions, and downhill speed control supports safety and comfort. The cab is quieter and more spacious, with improved visibility and comforts like a temperature-controlled storage box, Bluetooth connectivity, and USB charging ports. Maintenance is safer and faster thanks to longer service intervals and easier component access.

3. Caterpillar

Caterpillar's seven ADT models are engineered for harsh job sites across the globe, including soft terrain and rugged haul roads.

The EJ models include an ejector system that enhances productivity by allowing continuous material discharge without lifting the bed. Design priorities emphasize uptime, operator comfort, safety, and intuitive operation. Each truck is equipped with standard features that reduce operator input, such as assisted hoist, stability assist, and automatic retarding control.

The next-generation 725, 730, 730 EJ, and 735 models add advanced technology, including dynamic rollover protection, auto wait brake, push-to-start ignition, LED lighting, updated keypads, and an optional object detection system with multi-view camera. These upgrades aim to improve operational safety, ease of use, and throughput in high-volume environments.  

4. John Deere Construction & Forestry 

John Deere currently offers four ADT models. This lineup offers a wide range of payload capacities and delivers the power and torque for exceptional power-to-weight ratios that allow operators to work efficiently.

The full lineup features on-board diagnostics that help the operator monitor the health and productivity of their machine. In addition, smart features such as auto-differential lock, tire-pressure monitoring, and on-board payload weighing help boost productivity and uptime while helping to keep operating costs down.

5. DEVELON

DEVELON offers two ADT models in North America. These trucks are designed for demanding hauling on construction sites, for road projects, and in mining and quarrying environments. 

DEVELON ADTs feature a front-mounted turning ring coupled with a free-swinging rear tandem gear-driven bogie. This ensures maximum ground contact for smooth rides and optimal traction on rough and soft terrains.

The trucks' limited-slip differentials further enhance power transfer to the wheels with the best grip. A self-leveling front suspension is another key feature of DEVELON ADTs. The hydro-gas system provides enhanced shock absorption, contributing to a smoother ride and improved operator comfort.

DEVELON ADT cabs are designed for comfort, featuring air conditioning, heated air suspension seats, precise steering, good visibility, and low noise levels. The trucks are equipped with a vehicle control unit for displaying critical information on an in-cab monitor.

6. Rokbak

Rokbak's two ADTs are built to handle tough conditions across a variety of applications, including construction, quarrying, and mining.

These haulers combine strength, simplicity, and smart design to deliver high productivity with low operating costs. Both haulers are engineered for demanding off-road environments, offering excellent traction, stability, fuel efficiency, and low total cost-of-ownership.

Equipped with powerful engines and durable drivetrains, Rokbak ADTs provide consistent performance on steep grades, soft ground, and rough terrain. They also feature spacious, comfortable, ergonomic cabs with intuitive controls, enhancing operator safety and efficiency.

7. Komatsu

Komatsu's two ADTs are built for tough construction and mining applications. Standard features include Komatsu Traction Control System (KTCS), which automatically manages inter-axle locking and braking for improved traction.

K-ATOMiCS transmission technology and hydro-pneumatic suspension help deliver a smoother ride. Komtrax telematics is standard with no subscription fees for the life of the machine. Options include Komatsu Care programs, extended coverage, and a range of equipment and tire upgrades.

8. HD Hyundai Construction Equipment North America

Hyundai offers two ADTs. The HA30 offers a compact design ideal for tighter job sites. It is manoeuvrable with a high power-to-weight ratio and excellent fuel efficiency.

Its front-mounted differential and transmission allow for a tight turning radius and enhanced stability. The larger HA45 is built for heavy-duty hauling, featuring a reinforced frame and higher load capacity without compromising agility.

Both models come standard with Hyundai's Hi MATE telematics system for remote diagnostics and fleet management. These ADTs offer ergonomic cabs, simplified maintenance, and safety innovations including anti-slip control and hill-start assist.

9. Hydrema

Hydrema manufactures a range of compact articulated dump trucks and one full-size ADT, the 922G series, which is available in several variants. The 922G has a 20-ton capacity with dual axles at the rear and a 314-hp engine, offering an optimized power-to-weight ratio for demanding construction applications.

Hydrema's articulated design delivers excellent manoeuvrability and stability on challenging terrain and inclines. All models feature easy operator access, efficient maintenance design, and integrated telematics for fleet tracking. 

10. Bell Equipment

Bell Equipment's technologically advanced ADT range is offered globally with 10 variations available, including three 4x4 models and seven 6x6 models. Powered by Mercedes-Benz engines, Bell ADTs are compatible with hydro vegetable oil without the need to change components and service intervals.

Bell incorporates its own on-board weighing and telematics system, Fleetm@tic. Using accurate on-board weighing data, Fleetm@tic provides load and production figures, along with other useful information.

Features promoting safer operation include Hill Hold and Tip Safe. They prevent rollback on slopes and rollovers due to tipping at unsafe angles. Bell ADTs integrate with third-party proximity detection systems (PDS) and collision avoidance systems as standard, as well as autonomous and remote-control systems.
