G-Series Articulated Haulers Reinvent a Classic

The Volvo G-Series articulated haulers — including the A35G, A35G FS, A40G and A40G FS — are suited to a wide variety of applications in quarries, mining and earthmoving, according to the manufacturer.

The turbocharged six-cylinder Volvo engines have been redesigned to adhere to stringent Tier IV Final emissions regulations. The Volvo drivetrain and an inline dropbox designed for high ground clearance are purpose-built to ensure harmony and optimized performance. The drivetrain’s design delivers high rimpull, lowers fuel consumption and provides reliability in heavy-duty applications. Oil-cooled wet multiple disc brakes on the A35 and A40 models reduce maintenance costs and increase uptime, even on muddy or dusty job sites. The retardation system controls downhill hauling speeds using wheel brakes and the Volvo engine brake.

To keep the G-Series sure-footed in even the most demanding job sites, automatic traction control (ATC) and differential locks are standard. The ATC system automatically switches between drive combinations of 6 x 6 and 6 x 4 to ensure lower fuel consumption or maximum traction when needed. If necessary, all differentials can be 100 percent locked, causing all wheels to rotate at the same speed for maximized traction in slippery conditions.

With the A35G FS and A40G FS, full hydraulic suspension on all wheels increases productivity and makes for a more comfortable ride — not to mention performance and high hauling speeds in tough conditions, according to the manufacturer.

The A35G, A35G FS, A40G and A40G FS can be equipped with an onboard weighing system, which allows for precise machine productivity monitoring, helping to optimize payload and minimize wear, tire damage and fuel consumption. On FS models, the system uses full suspension pressure sensors to monitor weight, relaying information to load software integrated into the machine’s electronics. Indicator lights tell the hauler operator, as well as the operator of the loading unit, whether the hauler is at part or nominal load or whether it has been overloaded.

The maintenance-free rotating hitch that connects the tractor to the trailer enables high ground clearance, boosting accessibility and drivability in tough conditions and maximizing uptime.

The centrally positioned ROPS/FOPS-equipped Volvo Care Cab gives the operator a commanding view of the job site, and ergonomically positioned controls are designed for ease of use. An optional air-suspended seat, optional armrests and head restraints, and low noise levels further increase operator comfort and productivity.

Without a threshold to cross, the cab can be easily and safely entered through a wide-opening door. And the G-Series climate control system comes with the cleanest air filtration system in the industry for clearer breathing — even on dusty job sites.

Maintenance, Managed

The G-Series provides machine owners, operators and technicians with access to a wealth of data that promotes greater uptime — thereby lowering costs and increasing productivity. These machines come fitted as standard with CareTrack, the Volvo telematics system. Accessed remotely, CareTrack provides machine information such as fuel consumption and service reminders that allow improved planning and operation.

The machine monitors operation, and the MATRIS system collects this information, helping to optimize performance and fuel efficiency by tracking activity and identifying areas for improvement. It also allows machine owners to collect the same data as CareTrack, even if CareTrack is not available in their area. The Contronics system continuously monitors fluid levels and relays diagnostic information to a screen in the cab, providing warning messages to alert the operator to problems early on — reducing downtime and promoting operator safety.

G-Series articulated haulers are designed for safe and easy maintenance, with a front grill that swings down and functions as a service platform with anti-slip steps. The engine compartment has a 90-degree tilting hood for easy access to filters and service points. On the new models, the hydraulic tank, after-treatment system, muffler, fuel tank and refueling pipe have all been relocated to more intuitive locations, allowing for even easier maintenance.
