Dump trucks are some of the most used and useful heavy-duty vehicles seen on highways and construction sites. Although their function is quite simple, the number of different types of dump trucks in use is numerous, specialized for many different jobs and materials. Before purchasing a new or used dump truck, be sure to determine whether a standard type or a more versatile articulated design will be the best choice for your intended use.

Articulated Dump Truck – Beginnings

Also known as an articulated truck, this new type of dump truck design arose out of necessity when the regular design of these vehicles did not meet the needs of working on certain types of terrain. Construction companies were increasingly forced to redesign this useful work truck as it was found to be limited when it came to maneuvering on a construction site consisting of deep or uneven ground contour, hills, mounds or similar obstacles that prevented the normal use of a vehicle with a standard structure that transports tons of material.

Some early versions of dump trucks were designed to be joined in the middle so that the vehicle was not a complete, inflexible unit; then Volvo designed the first ADT which went into commercial production in 1959. The trucks were developed with the main drive axle repositioned at the rear of the tractor to provide maximum traction and excellent manoeuvrability. Steered by a hydraulic system with levers instead of a steering wheel, turning and moving over rough or mountainous terrain was made much easier with this particular axle location, and the result was a two-part joint vehicle that was more stable and less rigid. .

Articulated Dumpers – Current Design

With improvements in vehicle and equipment technology, the ADT has been transformed into a rugged, versatile and powerful vehicle that is much easier to use than its predecessors – this dynamic work vehicle can get in, out and over almost any type of terrain. . . Modern versions are built today not only by Volvo, but also by Terex, Caterpillar, John Deere, Moxy, and a few other dump truck manufacturers. These vehicles are typically four-wheel drive, manual or automatic, and ride on large construction-ready knobby tires that can traverse deep and slippery surfaces. A transmission shaft is used that is articulated through joints provided with grooves; newer models are made with stick or conventional steering.

Having the increased driveability isn’t the only improvement seen with the ADT. They can be equipped with different types of dump decks, from standard to side dumpers, scraper decks and other specialized types that will suit the different needs these trucks must handle.

Articulated Dumpers – Main Benefits of Use

The practical benefits of an ADT over conventional rigid frame dump trucks are numerous. Although conventional trucks can carry ever-increasing loads, doing so can be dangerous and inefficient if the vehicle is unable to navigate the job site terrain. Preventing truck accidents, getting stuck and being unable to maneuver around tight turns, corners, hills, valleys and other obstacles with this style of drivetrain and design is truly possible, taking much of the risk out of the work these vehicles normally do, as well as increase efficiency in the workplace. Although a typical ADT does not haul as much as conventional models, it is still more efficient when you take into account the potential for the issues listed above, as well as increased fuel use when negotiating a larger, heavier truck through job sites. on difficult terrain.

ADTs may not be needed as much on smaller job sites or to transport material longer distances; however, those companies facing difficult work situations will benefit greatly from adding an ADT to the work fleet. In fact, history has taken an ordinary dump truck and produced a hard-working, ground-covering version of the articulated dump truck.
