Volvo CE has launched a new G Series of articulated dump trucks (ADTs) at ConExpo-Con/AGG 2014, fitted with Tier 4 Final/Stage IV-compliant engines.

Designed to adhere to the strict emissions laws that came into force in North America and Europe at the start of this year, the G Series consists of the 24 tonne capacity A25G; 28 tonne capacity A30G; 33.5 tonne capacity A35G and A35G FS; and the 39 tonne capacity A40G and A40G FS models.

All models boast Volvo CE’s new Stage IV/Tier 4 Final-compliant turbocharged six-cylinder engines, with gross power ranging from 235 kW to 350 kW.

Other on-board technology includes a retardation system to control downhill hauling speeds using wheel brakes and the Volvo engine brake, together with automatic traction control (ATC) and differential locks as standard.

The ATC system automatically switches between drive combinations of 6x6 and 6x4 to ensure lower fuel consumption or provide maximum traction when needed. If necessary, all differentials can be 100% locked, causing all wheels to rotate at the same speed for maximised traction in slippery conditions.

With the A35G FS and A40G FS, full hydraulic suspension on all wheels is said to increase productivity and make for a more comfortable ride, while the A35G, A35G FS, A40G and A40G FS models can be equipped with Volvo’s on-board weighing system.

This technology allows for precise machine productivity monitoring, and is said to help to optimise payload and minimise wear, tire damage and fuel consumption.

On FS models, the system uses full suspension pressure sensors to monitor weight, relaying information to 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 machines also come fitted as standard with CareTrack, Volvo CE’s telematics system. Accessed remotely, CareTrack provides machine information such as fuel consumption and service reminders that allow improved planning and operation.
