Off-Road Hauling

Off-road trucks haul material where highway trucks cannot operate. Articulated dump trucks lead the class, carrying loads across soft, steep, and unimproved ground.

Articulated Dump Truck

Cómo funciona

The articulation joint lets the front and rear frames roll independently, keeping six driven wheels in ground contact where a rigid chassis would lift wheels and lose traction. Payloads in the 25-45 t range travel from cut to fill over grades and surfaces that would stop an on-road truck.

Tipos y variantes

Articulated Dump Truck: Off-road hauler with a pivoting frame that carries material over rough or soft ground.
Truck Unloader: Conveyor or elevator system that unloads bulk material from trucks.

Cómo elegir

ADTs earn their place when haul roads are soft, steep, or temporary — mass excavation, mine and quarry support, and wet-season earthmoving. Payload class is matched to the loading tool's cycle so the excavator or loader fills a truck in an efficient number of passes; on firm, established haul roads, rigid or on-road trucks may move material at lower cost.

Preguntas frecuentes

What is the difference between an articulated and a rigid dump truck?

The center hinge. An ADT flexes to keep all wheels driving over rough, soft ground; rigid haulers carry more on well-built haul roads but demand them.

Where do articulated trucks fit on an earthmoving job?

Between the loading tool and the fill or stockpile — hauling mass excavation, structural fill, and topsoil over ground too poor for highway trucks.

Can off-road trucks work on wet sites?

That is their design case: all-wheel drive, flotation tires, and frame articulation keep them productive in mud and on grades where other haulers bog down.
