Volvo puts own stamp on grader

Volvo has completed the integration of the Champion brand of motor graders, bought five years ago, with the launch of its new B-series. The new machines feature Volvo's own engines, transmission, and a redesigned cab.

In the seven machine range are two all-wheel drive graders, including the 16.6t G746B, according to Volvo the most powerful all-wheel drive grader in the industry with a maximum power output of 181kW. There are also five tandem drive machines ranging from 14t to just under 20t.

Two engines are used in the range - 7.1 litre and 9.6 litre stage II compliant diesels - with outputs from 105kW to 181kW and equipped with Volvo's variable horsepower system. These engines are said to match fuel efficiency with high torque at low revs to facilitate control across all speeds.

Transmission is via the proven Volvo 8400 box with eight forward and four reverse ratios including five speeds below 17.7km/h (11mph), a high-speed road maintenance gear, a snow-ploughing speed and a gear for high-speed roading.

Disengaging the drive to the front wheels is done at the flick of a switch and the machines can be operated in creep mode (where only the front wheels are driven) at speeds of up to 3.2km/h (2mph).

Inside the redesigned cab, the seat and control pedestal can be adjusted independently, while the controls and gauges are arranged in a 90û arc to the front and right of the operator.

The Contronic Monitoring System used on Volvo's wheeled loaders, excavators and ADT's has also been adapted for use on the graders and has become the nerve centre of the machine.
