Bell ADTs are equipped for heavy-duty downhill hauling on mass earthmoving projects

For RTG Investment and Agua Construction, breaking ground on their first project in the United States marks an exciting new chapter for their global real estate development business. With successful developments across Europe and Asia, RTG's latest venture brings them stateside to a sprawling 1,000-acre site where they are developing approximately 315 homes. To complete the earthworks phase on this vast project, they have purchased four Bell Trucks America B45E articulated dump trucks (ADTs).

The conductor of this major earthmoving effort is Artavazd Stepanyan, construction manager for RTG Investment and Agua Construction. Tasked with managing the groundwork for this large-scale project, Stepanyan knew the success of the job would rely heavily on selecting the right heavy equipment for the job, which led him to find his local Bell Trucks dealer, Powerscreen of California, Nevada & Hawaii.

The right machines

Faced with the challenge of moving huge volumes of dirt and rock from the top of the project's hilly terrain down to the lower lots where compaction and grading are critical, Stepanyan made the strategic decision to purchase the four Bell B45E ADTs. "These trucks are a major part of our project," Stepanyan says. "They are responsible for hauling material from the top of the hills down to the lower sections where we need that material for compaction."

A standout feature to Artavazd is the Fleetm@tic payload monitoring system that provides ease of calculating and keeping track of the cubic yards that are moved daily by the trucks.

High-performance hauling

The Bell B45E ADT has become known for its outstanding performance, fuel efficiency, and smart design, making it the ideal choice for demanding earthmoving tasks like those at RTG's development site. Key features of the Bell B45E include its nominal payload of 90,390 pounds, 523 hp at 1,700 rpm from a six-cylinder Mercedes-Benz off-highway diesel engine, Allison transmission for smooth, reliable power delivery, and 6 to 7 percent lower cost per ton compared to previous D series models. This optimized power-to-weight ratio, along with excellent fuel efficiency, gives the B45E a clear edge when it comes to large-scale hauling operations. Another feature that caught Artavazd's attention was the truck's on-board monitoring systems. "It's very important for me to be able to monitor the fuel burn levels we are doing, and that information is easily accessible on the B45Es," he notes.

Dealer expertise 

Artavazd knew he needed dependable, high-capacity equipment and a trusted partner who could support RTG's first U.S. project. That's where Tom O'Malley of Powerscreen of California, Nevada & Hawaii came in.

"Tom is a great guy," Stepanyan says. "He spent the time explaining why the B45E ADT was the right choice for our project. He has been fast to respond whenever there is any issue with the trucks, and I know I can trust him."

With strong dealer support and high-performing machinery on their side, RTG Investment and Agua Construction are well-positioned to bring their first U.S. development to life successfully and efficiently.
